For a well-rounded starting point, I’d put MegaFood Blood Builder first for its vegan formula and supporting nutrients; NOW Supplements Iron 18 mg is a simpler, lower-dose option, while Thorne Iron Bisglycinate stands out for shoppers focused on a chelated form. The main tradeoffs are iron dose, ingredient complexity, pill size, and whether you prefer capsules, tablets, liquid, or gummies. A higher dose is not automatically a better match, since individual needs vary and too much iron can be harmful. I compare all 15 options by formula, usability, and fit so you can narrow the field—read on for the full breakdown.

Key Takeaways
- MegaFood Blood Builder leads for a balanced vegan formula, while its mini-tablet and larger-bottle versions suit different swallowing and supply preferences.
- NOW Supplements Iron 18 mg and Amazon Basics Vegan Iron 18 mg keep the formula simpler and the dose lower than many 25–65 mg options.
- Chelated bisglycinate choices, including Thorne, PlantFusion, and Future Kind, appeal to buyers prioritizing iron form over a whole-food blend.
- The lineup spans capsules, tablets, mini tablets, liquid, and gummies, but alternative formats may involve tradeoffs in dose clarity, added ingredients, or serving convenience.
- Nature’s Bounty Iron 65 mg has the highest listed dose in this group; that makes clinician guidance especially relevant rather than making it a default pick.

More Details on Our Top Picks
NOW Supplements Iron 18 mg, 120 Vegetarian Capsules
NOW Supplements Iron pairs an 18 mg dose with Ferrochel iron bisglycinate, making it a measured, simple choice for adults seeking a vegan iron supplement without added vitamins or food blends. Its capsule form and stated exclusions—including dairy, eggs, gluten, nuts, and soy—may suit shoppers managing common dietary restrictions. Compared with Nature’s Bounty Iron, which supplies 65 mg of elemental iron as ferrous sulfate, this is the lower-dose option and may be a better fit for someone who does not want that higher amount unless advised by a clinician. The tradeoff is a shorter supply than Amazon Basics Vegan Iron’s 195 capsules, and the formula lacks the vitamin C, B12, and folate found in MegaFood Blood Builder. Choose it for a focused bisglycinate formula, not an all-in-one blend.
Pros:- 18 mg iron per serving from Ferrochel iron bisglycinate
- Vegan vegetarian capsules
- Free from dairy, eggs, gluten, nuts, and soy, according to the product information
- Non-GMO, Halal, Kosher, and GMP Quality Assured classifications
Cons:- Does not include vitamin C, B12, or folate
- 120 capsules are fewer than Amazon Basics Vegan Iron’s 195-capsule bottle
- The supplied information does not specify a daily serving schedule
Best for: Adults seeking a vegan 18 mg bisglycinate supplement with a short list of stated allergen exclusions.
Not ideal for: Shoppers who want iron paired with vitamin C, B12, or folate, or who need a clinician-directed higher dose.
- Iron per serving:18 mg
- Iron form:Iron bisglycinate (Ferrochel)
- Quantity:120 capsules
- Capsule type:Vegetarian
- Dietary exclusions listed:Dairy, eggs, gluten, nuts, and soy
- Classifications:Non-GMO, Halal, Kosher, GMP Quality Assured
Our verdict“Pick NOW Supplements if you want a vegan 18 mg bisglycinate formula with stated allergen exclusions and no extra blend ingredients.”
Nature’s Bounty Iron 65 mg, Ferrous Sulfate 325 mg, 100 Tablets
Nature’s Bounty Iron stands apart in this lineup for its 65 mg of elemental iron per tablet, supplied as 325 mg ferrous sulfate. That makes it a distinctly higher-dose option than NOW Supplements Iron at 18 mg or MegaFood Blood Builder at 26 mg; the difference matters because buyers should not treat these amounts as interchangeable. Its focused tablet formula does not add the vitamin C, B12, and folate included in MegaFood Blood Builder, so it suits someone whose clinician has recommended this type and amount of iron rather than a buyer seeking a broad blend. The product details list 100 tablets but provide little information about dietary certifications, allergens, or tablet excipients. I would choose it only when the higher elemental-iron amount matches specific guidance, not as a casual step up from a lower-dose vegan supplement.
Pros:- Provides 65 mg elemental iron per tablet
- Identifies the iron source as 325 mg ferrous sulfate
- 100 tablets per package
- Straightforward formula focused on iron
Cons:- The supplied product details do not confirm that the tablets are vegan
- Its 65 mg dose is substantially higher than the 18 mg NOW and Amazon Basics options
- No added vitamin C, B12, or folate is listed
Best for: Adults whose healthcare professional has recommended a 65 mg elemental-iron tablet and who want a simple ferrous sulfate formula.
Not ideal for: Shoppers choosing a vegan supplement who need confirmed vegan status, or those seeking a lower-dose bisglycinate formula or added nutrients.
- Brand:Nature’s Bounty
- Elemental iron per tablet:65 mg
- Ferrous sulfate per tablet:325 mg
- Form:Tablet
- Count:100 tablets
Our verdict“Choose this only if you need a 65 mg ferrous sulfate tablet and have confirmed both the dose and vegan suitability for your needs.”
MegaFood Blood Builder Iron Supplement, Vegan, 90 Tablets
MegaFood Blood Builder earns its place for combining 26 mg of iron with vitamin C, folic acid, and B12 in a one-tablet serving. That gives it a broader nutrient profile than NOW Supplements Iron, which focuses on bisglycinate, and more support ingredients than Amazon Basics Vegan Iron’s 18 mg capsule. The product information says it can be taken any time of day, including on an empty stomach, which may appeal to buyers who want fewer timing constraints. It is also vegan and Non-GMO Project verified, with a stated list of common allergens it excludes. The tradeoffs: its iron amount is higher than the 18 mg options, it is intended for adults rather than children, and the added nutrients may be unnecessary for someone who wants iron alone. This is the most rounded pick here, not the simplest.
Pros:- 26 mg iron per one-tablet serving
- Includes vitamin C, folic acid, and vitamin B12
- Product information says it can be taken on an empty stomach
- Vegan, Non-GMO Project verified, and free from several listed common allergens
Cons:- Not intended for children
- Provides more iron than the 18 mg NOW Supplements and Amazon Basics options
- Added nutrients may not suit buyers seeking a minimal-ingredient iron supplement
Best for: Adults who want a vegan iron tablet with vitamin C, folic acid, and B12 in a single serving.
Not ideal for: Children, adults seeking an iron-only formula, or shoppers who prefer a lower 18 mg dose.
- Iron per serving:26 mg
- Serving size:1 tablet
- Count:90 tablets
- Added nutrients:Vitamin C, folic acid, and vitamin B12
- Dietary suitability:Vegan, vegetarian, kosher
- Certification:Non-GMO Project verified
- Testing:Tested for 150 chemical substances
- Listed exclusions:Gluten, dairy, eggs, tree nuts, peanuts, soy, fish, shellfish, and sesame
Our verdict“Choose MegaFood Blood Builder if you want a vegan adult formula that combines iron with vitamin C, folic acid, and B12.”
Amazon Basics Vegan Iron 18 mg, 195 Capsules
Amazon Basics Vegan Iron is the practical pick for shoppers who want a once-daily 18 mg bisglycinate capsule in a larger bottle. Its 195-capsule count is a clear advantage over NOW Supplements Iron’s 120 capsules and Garden of Life Vitamin Code Raw Iron’s 30, while the 18 mg amount matches NOW’s dose. That makes it a straightforward alternative to MegaFood Blood Builder for buyers who do not want added vitamin C, folate, or B12. The formula is vegan and gluten free, and the product information says it is made without artificial colors, flavors, or chemical preservatives. A meaningful caveat is storage: heat or sunlight exposure may damage the product, so it needs suitable storage. Its manufacturing details are provided, but the supplied data do not list certifications such as Non-GMO Project verification.
Pros:- 18 mg iron per serving as ferrous bisglycinate
- 195 capsules, with a stated six-month supply at the listed daily serving
- Vegan and gluten free
- Made without artificial colors, flavors, or chemical preservatives
Cons:- Heat or sunlight exposure may damage the product
- Does not list vitamin C, B12, or folate
- The supplied information does not list third-party dietary certifications
Best for: Adults who want an 18 mg vegan bisglycinate capsule and value a larger bottle for a daily routine.
Not ideal for: Shoppers who want a multi-nutrient formula, a small bottle for occasional use, or a product less sensitive to heat and sunlight exposure.
- Iron per serving:18 mg
- Iron form:Ferrous bisglycinate
- Quantity:195 capsules
- Supply:Six months when taken daily at the listed serving size
- Dietary features:Vegan, gluten free
- Manufacturing:GMP facility in the USA; US and imported ingredients
- Storage caution:Heat or sunlight exposure may damage the product
Our verdict“Choose Amazon Basics Vegan Iron for a larger supply of simple 18 mg bisglycinate capsules, provided you can store it away from heat and sunlight.”
Garden of Life Vitamin Code Raw Iron Supplement, 30 Capsules
Garden of Life Vitamin Code Raw Iron suits buyers who want iron packaged with a wide range of supporting ingredients rather than a minimal capsule. Each serving provides 22 mg of iron alongside vitamin C, B12, folate, probiotics, digestive enzymes, and 23 powdered organic fruits and vegetables. Compared with the more focused 18 mg NOW Supplements Iron, this is a much broader blend; compared with MegaFood Blood Builder, it adds probiotics, enzymes, and produce powders but provides less iron per serving. The capsule can also be opened and mixed with water or juice, offering another way to take it. That flexibility comes with tradeoffs: the 30-capsule bottle is smaller than the other featured bottles, and the extra ingredients may be unnecessary for shoppers who only want iron. Its vegan, Non-GMO Project Verified, and NSF Certified Gluten-Free credentials help define its appeal.
Pros:- 22 mg iron with vitamin C, B12, and folate
- Includes probiotics, digestive enzymes, and 23 powdered organic fruits and vegetables
- Capsule contents may be mixed with water or juice
- Vegan, Non-GMO Project Verified, and NSF Certified Gluten-Free
Cons:- 30 capsules provide a smaller bottle count than the other featured options
- The broad ingredient blend may not suit buyers seeking iron alone
- The 22 mg amount may not match every individual’s needs
Best for: Adults who want a vegan iron capsule with added vitamins, probiotics, enzymes, and fruit and vegetable powders, plus the option to mix its contents into a drink.
Not ideal for: Shoppers who want an iron-only formula, a longer bottle supply, or a dose selected to meet individual clinical needs without extra ingredients.
- Iron per serving:22 mg
- Serving size:1 capsule
- Count:30 capsules
- Additional nutrients:Vitamin C, vitamin B12, folate, probiotics, and digestive enzymes
- Produce ingredients:23 powdered organic fruits and vegetables
- Dietary features:Vegan, RAW
- Certifications:Non-GMO Project Verified, NSF Certified Gluten-Free
- Directions:Adults take 1 capsule daily, with or without food; contents may be mixed with water or juice
Our verdict“Choose Garden of Life Vitamin Code Raw Iron if you want a vegan iron supplement with added nutrients and drink-mixable capsule contents, rather than a minimal formula.”
PlantFusion Vegan Iron Supplement with Ferrochel, 25 mg, 90 Capsules
PlantFusion pairs 25 mg of Ferrochel iron with folate and vitamin B12, making it a practical choice for shoppers who want those nutrients alongside their iron in one capsule. The once-daily serving is simpler than MegaFood Blood Builder, which calls for two mini tablets, and the formula also avoids gluten, dairy, and soy. Unlike Thorne Iron Bisglycinate, which focuses on iron and sport certification, PlantFusion’s selling point is its added B-vitamin combination. The tradeoff is that the listed formula does not include vitamin C, unlike NATURELO Vegan Iron, and its 25 mg iron dose may not match every person’s needs. I would choose it for a compact daily routine, not as a substitute for individualized advice about iron intake.
Pros:- Supplies 25 mg of iron as Ferrochel ferrous bisglycinate per capsule
- Includes folate and vitamin B12 in the same formula
- One capsule daily is simpler than MegaFood Blood Builder’s two-tablet serving
- Vegan and free of gluten, dairy, and soy
Cons:- Does not list vitamin C, unlike NATURELO Vegan Iron
- The 25 mg dose may not suit every individual’s iron needs
- A 90-capsule bottle provides a fixed supply with no smaller-count option listed
Best for: Adults seeking a vegan, once-daily iron capsule that also supplies folate and vitamin B12 and avoids gluten, dairy, and soy.
Not ideal for: Shoppers who specifically want vitamin C included with iron, or people whose clinician has recommended a different iron dose.
- Iron:25 mg per capsule as Ferrochel ferrous bisglycinate
- Folate:667 mcg DFE (400 mcg folic acid)
- Vitamin B12:25 mcg as cyanocobalamin
- Serving size:1 capsule daily
- Capsules per bottle:90
- Dietary attributes:Vegan, non-GMO, gluten-free, dairy-free, soy-free
- Other formulation details:No artificial colors, flavors, or preservatives
Our verdict“Choose PlantFusion if you want a single daily vegan capsule combining iron, folate, and B12, but compare its dose with professional guidance.”
MegaFood Blood Builder Iron Supplement, 72 Mini Tablets
MegaFood Blood Builder combines 26 mg of iron with vitamin C, folic acid, and B12, so it covers more supporting nutrients than the iron-only focus of Thorne Iron Bisglycinate. Its mini tablets may be easier to swallow than standard-size tablets, and the product is described as suitable to take on an empty stomach. The main catch is the serving: two mini tablets per dose, while PlantFusion provides its iron, folate, and B12 in one capsule. MegaFood also lists testing for 150 chemical substances, a useful point for buyers who value screening details. It is not intended for children, and a multi-nutrient formula may be unnecessary if a clinician has recommended iron alone or a different combination.
Pros:- Combines 26 mg of iron with vitamin C, folic acid, and vitamin B12
- Mini-tablet format may suit people who dislike larger pills
- Described as suitable for taking on an empty stomach
- Lists testing for 150 chemical substances
Cons:- Requires two mini tablets per serving
- Not intended for children
- Adds several nutrients that may not be needed by people seeking iron alone
Best for: Adults who want iron, vitamin C, folic acid, and B12 together and prefer mini tablets over larger pills.
Not ideal for: Children, people who want a one-pill serving, or shoppers seeking an iron-only formula such as Thorne Iron Bisglycinate.
- Form:Mini tablets
- Count:72 tablets
- Iron per serving:26 mg
- Iron form:Iron bisglycinate
- Key added nutrients:Vitamin C, folic acid, vitamin B12
- Serving directions:Take 2 mini tablets with a beverage
- Dietary suitability:Vegan and kosher
- Testing:Tested for 150 chemical substances
Our verdict“Pick MegaFood Blood Builder if you want a multi-nutrient iron formula in mini tablets and are comfortable taking two per serving.”
NATURELO Vegan Iron Supplement with Vitamin C and Organic Whole Foods, 90 Count
NATURELO stands out for pairing ferrous bisglycinate with vitamin C, appealing to buyers who want both in one vegan supplement. That combination gives it a different emphasis from PlantFusion, which includes folate and B12 but does not list vitamin C, and from Thorne, whose supplied product details focus on iron and sport certification. The formula also avoids gluten, soy, coloring, preservatives, and flavoring, with manufacturing in a GMP-certified facility. The information provided does not state the iron amount per serving, however, which makes it harder to compare dose-for-dose with the 25 mg options from PlantFusion, Thorne, and Solgar. I would favor it for its ingredient pairing, but not for anyone who needs a clearly specified iron dose before choosing.
Pros:- Pairs ferrous bisglycinate chelate with vitamin C
- Vegan and non-GMO
- Free of gluten and soy
- Made without coloring, preservatives, or flavoring
Cons:- The supplied product details do not state the iron amount per serving
- Suitability may vary by individual, so the formula is not a one-size-fits-all choice
- Does not list folate or B12, unlike PlantFusion and MegaFood Blood Builder
Best for: Vegan adults who want vitamin C included alongside chelated iron and prefer a formula without gluten, soy, colors, preservatives, or flavoring.
Not ideal for: Dose-focused shoppers who need a stated iron amount to compare against a clinician’s recommendation or products such as Solgar Gentle Iron.
- Iron form:Ferrous bisglycinate chelate
- Added nutrient:Vitamin C
- Count:90
- Dietary attributes:Vegan, non-GMO, gluten-free, soy-free
- Manufacturing:Made in a GMP-certified facility
- Coloring and preservatives:No coloring or preservatives
- Flavoring:No flavoring
Our verdict“Choose NATURELO if vitamin C alongside chelated iron matters more to you than having a clearly stated iron dose or added B vitamins.”
Thorne Iron Bisglycinate, 25 mg, 60 Capsules
Thorne offers a clearly stated 25 mg of elemental iron per capsule in bisglycinate form, with NSF Certified for Sport verification for label compliance and banned-substance screening. That makes it the most directly sport-focused option in this group, unlike Solgar Gentle Iron, which emphasizes a larger 180-capsule supply, or MegaFood Blood Builder, which adds vitamin C, folic acid, and B12. Thorne’s narrower formula suits buyers who want a straightforward iron capsule rather than a blend of supporting nutrients. Its tradeoff is the shorter 60-capsule count and the absence of added nutrients listed in MegaFood or PlantFusion. The description characterizes the iron form as non-constipating, but individual responses can differ; buyers should still match the dose to their needs.
Pros:- Provides 25 mg of elemental iron per capsule
- Uses iron bisglycinate, described as well absorbed and non-constipating
- NSF Certified for Sport for label compliance and banned-substance testing
Cons:- The 60-capsule count is lower than Solgar Gentle Iron’s 180 capsules
- No added vitamin C, folate, or B12 is listed
- The 25 mg dose may not fit every individual’s needs
Best for: Vegan athletes or tested-sport participants seeking a specified 25 mg iron capsule with NSF Certified for Sport screening.
Not ideal for: Shoppers who want vitamin C, folate, or B12 included, or those prioritizing a larger bottle like Solgar’s 180-capsule supply.
- Form:Capsules
- Count:60 capsules
- Elemental iron:25 mg per capsule
- Iron form:Iron bisglycinate
- Certification:NSF Certified for Sport
- Certification scope:Testing for label compliance and banned substances
Our verdict“Thorne is the clearest fit for sport-tested buyers who want a defined 25 mg bisglycinate capsule without extra nutrients.”
Solgar Gentle Iron 25 mg, 180 Vegetable Capsules
Solgar Gentle Iron combines 25 mg of iron per serving with a 180-capsule bottle, making it the standout choice here for buyers who want a larger supply of a straightforward vegan formula. Its chelated iron is described as gentle on the stomach and non-constipating, while the ingredient exclusions include gluten, wheat, dairy, soy, yeast, sugar, sodium, artificial flavors, sweeteners, and colors. Compared with Thorne Iron Bisglycinate, Solgar offers three times as many capsules, but Thorne adds NSF Certified for Sport testing. Unlike PlantFusion and MegaFood Blood Builder, Solgar does not list folate, B12, or vitamin C. The larger count is useful only if the dose suits you; iron supplementation is not appropriate for everyone, so this is not a reason to take iron without guidance.
Pros:- Provides 25 mg of iron per serving in a chelated formula
- 180 vegetable capsules offer a larger supply than Thorne’s 60-capsule bottle
- Described as gentle on the stomach and non-constipating
- Vegan and free of gluten, wheat, dairy, soy, yeast, sugar, sodium, and listed artificial additives
Cons:- Does not list vitamin C, folate, or B12, unlike MegaFood Blood Builder
- A large bottle may be a poor fit if the dose is not suitable or tolerated
- Iron supplements may not be appropriate for everyone
Best for: Vegan adults who want a larger bottle of 25 mg chelated iron and do not need added vitamin C, folate, or B12.
Not ideal for: People seeking a multi-nutrient formula, sport certification, or a dose selected without clinical guidance.
- Form:Vegetable capsules
- Quantity:180 capsules
- Iron per serving:25 mg
- Iron formula:Chelated
- Dietary suitability:Vegan and gluten-free
- Free of:Wheat, dairy, soy, yeast, sugar, sodium, artificial flavors, sweeteners, and colors
- Stomach tolerance description:Designed to be gentle on the stomach and non-constipating
Our verdict“Choose Solgar for a larger supply of straightforward vegan chelated iron, provided its 25 mg serving matches your needs.”
Deva Nutrition Vegan Chelated Iron with Vitamin B-12, 29 mg, 90 Tablets, 2-Pack
The two-pack format makes this a practical pick for someone who wants a ready supply of vegan iron, while the 29 mg dose sits above MegaFood Blood Builder’s 26 mg per serving. Its amino acid chelate form and added B-12 distinguish it from simpler iron-only options, though the listing does not specify other nutrients such as vitamin C. Vegan Society registration offers a clear dietary credential, and the coated tablets are described as easy to swallow. Their 5/16-inch width may help with swallowing, but such small tablets can be harder to pick up or handle. I’d choose Deva for the two-pack and B-12 combination, not for a broad nutrient blend or a liquid format like MaryRuth’s.
Pros:- Amino acid chelated iron, with 29 mg per serving
- Includes vitamin B-12
- Vegan Society registered
- Two bottles provide 90 tablets each
Cons:- The 5/16-inch tablets may be difficult for some people to handle
- No vitamin C is listed among the included nutrients
- The listing does not state a specific adult age range or dosage schedule
Best for: Vegan adults who want a two-pack of chelated iron tablets with added B-12 and a clear vegan certification.
Not ideal for: People who have trouble handling very small tablets, or buyers seeking vitamin C in the same formula.
- Iron:29 mg
- Iron type:Amino acid chelate
- Added nutrient:Vitamin B-12
- Form:Coated tablets
- Quantity:90 tablets, 2-pack
- Tablet width:5/16 inch
- Dietary attributes:Vegan and vegetarian; registered by the Vegan Society
Our verdict“Choose Deva if you want a vegan-certified two-pack of chelated iron with B-12 and can comfortably handle small tablets.”
MegaFood Blood Builder Iron Supplement, 180 Tablets
Blood Builder’s 180-tablet bottle suits adults who prefer one larger supply over buying smaller bottles. Each serving has 26 mg of iron bisglycinate alongside vitamin C, folic acid, and B-12, making it a more rounded formula than Deva’s 29 mg iron-and-B-12 option. The stated directions allow one tablet any time of day, even on an empty stomach, which may fit people who find supplement timing inconvenient. The tradeoff is that this remains an adult formula, not a household choice for children; MaryRuth’s liquid, by contrast, is listed for ages four and up. The supplied description gives no clinical trial results, so I’d judge it by its listed ingredients and directions rather than assume a particular outcome.
Pros:- 26 mg of iron bisglycinate per serving
- Includes vitamin C, folic acid, and B-12
- Listed for use any time of day, including on an empty stomach
- Vegan, kosher, and non-GMO Project verified
Cons:- Not intended for children
- No detailed clinical trial results are provided in the description
- A 180-tablet bottle may be more supply than someone wanting a smaller trial quantity needs
Best for: Adults seeking a larger bottle of vegan iron with vitamin C, folic acid, and B-12, plus flexible timing.
Not ideal for: Parents looking for one iron product for children, or shoppers who want clinical trial evidence in the product information.
- Brand:MegaFood
- Iron per serving:26 mg
- Iron form:Iron bisglycinate
- Key nutrients:Vitamin C, folic acid, and vitamin B-12
- Form:Tablets
- Count:180 tablets
- Directions:1 tablet any time of day
- Dietary attributes:Vegan, kosher, and non-GMO Project verified
- Intended use:Adults
Our verdict“Pick this bottle if you’re an adult wanting a substantial supply of vegan iron with several supporting nutrients in one tablet.”
MaryRuth’s Liquid Iron Supplement for Adults and Children, Vegan, 15.22 fl oz
MaryRuth’s liquid format is the clearest alternative for people who dislike swallowing tablets or want a product listed for both adults and children ages four and up. It uses Ferrochel ferrous bisglycinate chelate and has a berry flavor, whereas MegaFood Blood Builder is a tablet with a specified 26 mg iron serving and a blend of added nutrients. The liquid may be easier to measure and swallow, but the supplied product details do not give an iron amount per serving, so buyers cannot compare its dose directly with the 29 mg Deva tablets or other dose-listed options here. Its dietary exclusions—dairy, nuts, gluten, and sugar—may suit some households, though it is not suitable for children under four.
Pros:- Liquid format can be easier to swallow and measure than tablets
- Listed for adults and children ages four and up
- Uses Ferrochel ferrous bisglycinate chelate
- Vegan and free of dairy, nuts, gluten, and sugar
Cons:- Iron amount per serving is not provided in the supplied product details
- Not suitable for children under four
- Berry flavor may not suit people who prefer unflavored supplements
Best for: Households with adults or children ages four and up who prefer a berry-flavored liquid to iron tablets.
Not ideal for: Buyers who need a clearly stated iron amount per serving for dose comparison, or caregivers of children under four.
- Volume:15.22 fl oz
- Form:Liquid
- Iron source:Ferrochel ferrous bisglycinate chelate
- Flavor:Berry
- Age suitability:Adults and children ages 4 and up
- Dietary attributes:Vegan, non-GMO, dairy-free, nut-free, gluten-free, and sugar-free
Our verdict“Choose MaryRuth’s if liquid delivery and age-four-and-up suitability matter more than having a listed iron dose for comparison.”
Vegan Iron Gummies for Adults and Kids, Peach, 90 Count
Peach-flavored pectin gummies offer a chewable alternative to the tablets in this roundup, with 10 mg of iron per serving from ferrous fumarate. That amount is lower than the stated 26 mg in MegaFood Blood Builder and 29 mg in Deva, so this pick is better for buyers whose preferred format and added nutrients matter more than matching those listed iron amounts. It also includes vitamin C, vitamin A, folic acid, zinc, and several B vitamins, giving it a broader ingredient list than the iron-and-B-12 combination in Deva. One practical gap remains: the description does not specify the serving size or age range despite the adults-and-kids title, so I would verify directions before choosing it for a child.
Pros:- Chewable peach flavor offers an alternative to tablets and liquid
- Provides 10 mg of iron per serving
- Includes vitamin C, vitamin A, folic acid, zinc, and B vitamins
- Pectin-based and listed as vegan, non-GMO, gluten-free, and soy-free

Our verdict“Choose these gummies if a peach-flavored chewable and a broad supporting-nutrient blend appeal more than a higher listed iron amount.”
Future Kind Iron Supplement with Vitamin C, Chelated Bisglycinate, 30 Capsules
Future Kind keeps the formula focused: one daily capsule supplies iron bisglycinate and 50 mg of vitamin C from acerola cherry. That straightforward routine contrasts with MegaFood Blood Builder, which adds folic acid and B-12, and with the larger 180-tablet MegaFood bottle. Future Kind’s 30-capsule count gives a month of daily servings according to the suggested use, but it offers less supply than either MegaFood or Deva’s two-pack. The listing states iron at 100% of the daily value rather than giving a milligram amount, which makes direct dose comparisons with the 26 mg MegaFood and 29 mg Deva products harder. I’d favor it for buyers who want a vegan capsule with vitamin C, not those who need a more fully described nutrient blend.
Pros:- Chelated iron bisglycinate
- Includes 50 mg of vitamin C from acerola cherry
- Suggested use is one capsule daily
- Vegan formula
Cons:- Iron is listed as 100% DV rather than a milligram amount
- 30-capsule count provides less supply than MegaFood’s 180-tablet bottle
- Does not list folic acid or B-12 among its nutrients
Best for: Vegan adults who want a one-capsule-a-day bisglycinate formula with vitamin C from acerola cherry.
Not ideal for: Shoppers who need the iron amount stated in milligrams for direct comparison, or who want folic acid and B-12 included.
- Form:Chelated iron bisglycinate
- Iron per serving:100% DV
- Vitamin C per serving:50 mg from acerola cherry
- Suggested use:1 capsule daily
- Capsule count:30
- Dietary type:Vegan
Our verdict“Pick Future Kind for a simple vegan daily capsule with vitamin C, provided a DV-based iron listing is enough for your comparison needs.”
How We Picked
I compared each product on factors that affect everyday use: stated iron amount, disclosed iron form, vegan suitability, added nutrients, serving format, and the clarity of the formula. I gave more weight to options that make it easier to match the supplement to a specific need than to products that simply provide more iron. Capsules and tablets can offer straightforward dosing, while liquid and gummies may help people who have difficulty swallowing but can bring different serving and ingredient tradeoffs.
The ranking reflects distinct buyer use cases, not a claim that one supplement is right for everyone. Broadly useful formulas rank ahead of more specialized or higher-dose choices; simpler lower-dose products remain strong alternatives for buyers who want fewer extras. I also account for the fact that product names and listed amounts alone cannot establish an individual’s iron needs, absorption, or tolerance. Since these 15 products are reviewed separately, this structure assigns comparative roles without claiming direct testing or medical outcomes.
Factors to Consider When Choosing Vegan Iron Supplements
Choosing a vegan iron supplement is less about finding the largest number on the label and more about matching dose, form, and format to your circumstances. I’d use the points below to frame a shortlist, then check the full Supplement Facts panel and discuss supplementation with a qualified health professional when appropriate.
Match the Dose to a Real Need
Labels in this roundup range from 18 mg to 65 mg of iron, so the products are not interchangeable simply because they all contain iron. Your need can depend on factors such as diet, life stage, health conditions, and lab results; a general multivitamin or supplement routine may also contribute iron. Avoid choosing by the largest dose or doubling up on products to compensate for uncertainty. Ask a clinician whether testing or a specific dose makes sense, especially if you have been told you have iron deficiency or take other supplements. A lower-dose product may be easier to fit into an existing routine, but it is not automatically sufficient for every person.
Read the Iron Form and the Full Label
Products may list forms such as ferrous sulfate, bisglycinate, or chelated iron, while blends can pair iron with vitamins or whole-food ingredients. The form tells you something about the formulation, but it does not by itself predict how well a particular person will tolerate or absorb it. Check the elemental iron amount per serving rather than relying on a compound’s total weight or the front-label number. Then review the complete ingredient list for allergens, sweeteners, flavorings, and nutrients you already get elsewhere. This step matters most when comparing a simple capsule with a more elaborate blend.
Choose a Format You Can Take Consistently
Capsules and tablets are compact and tend to make serving information easy to compare, but swallowing them may be a barrier for some people. Mini tablets can reduce that obstacle without changing the basic pill-taking routine. Liquid iron and gummies offer different textures and may suit people who avoid pills, yet their serving size, flavor, sugar or sweetener content, and storage instructions deserve a close read. Do not assume a child-oriented or adult-and-child label means the same serving is right for every age. The most practical format is the one you can take as directed while keeping the dose clear.
Treat Added Nutrients as a Formula Choice
Some options combine iron with vitamin C, B vitamins, or whole-food ingredients; others focus on iron alone. Added nutrients may suit shoppers who want a combined formula, but they can complicate the label and overlap with a multivitamin or other supplements. Compare each added ingredient with what you already take instead of treating a longer ingredient list as an automatic advantage. If you have dietary restrictions or sensitivities, inspect flavorings, coatings, and excipients as well as the headline ingredients. Simpler formulas can make it easier to identify what you are taking, while blends may reduce the number of separate products in a routine.
Plan Around Timing, Interactions, and Tolerance
Iron can interact with some medicines and minerals, and individual tolerance varies, so follow the product directions and ask a pharmacist or clinician about timing if you take medication. Calcium supplements, antacids, and some other products may affect how iron is absorbed when taken together. Some people also experience digestive discomfort, which can influence whether a high-dose or more complex product is a practical fit. Do not change a prescribed regimen or use a supplement to self-treat persistent symptoms without medical advice. A workable schedule and dose matter more than a theoretically attractive label.
Compare Supply Size With Serving Directions
A bottle’s capsule or tablet count does not tell you how long it will last until you check the serving size and directions. A larger count can be useful for a stable routine, but it is a poor match if you are still confirming your dose or tolerance. Multi-packs and large bottles can also be inconvenient if you need to change products after professional advice. Check expiration dates, storage requirements, and whether the serving instructions suit your schedule. I’d prioritize a format and quantity that support consistent, label-directed use over bulk alone.
Frequently Asked Questions
Should I choose an 18 mg supplement or a higher-dose option?
That depends on your individual iron status and the reason you are considering a supplement, not on which number looks more substantial. This lineup ranges from 18 mg options to a 65 mg product, so check the elemental iron amount per serving and compare it with any iron already in your diet or supplements. A higher dose may be appropriate in some circumstances, but it can also raise the chance of unwanted effects and is not a default upgrade. If you suspect deficiency, ask a healthcare professional about testing and a suitable plan before starting a high-dose product. Do not combine iron products unless you have been advised to do so.
Does vegan iron need to include vitamin C?
No, vitamin C is not a requirement for a supplement to be vegan or to contain iron. Several products in this roundup include vitamin C or other added nutrients, while simpler formulas focus more narrowly on iron. Whether a combined formula suits you depends on your diet, existing supplements, and preferences. Check the label for the amount of each nutrient and avoid accidentally duplicating ingredients across products. If you take medication or have a health condition, ask a clinician or pharmacist whether a particular combination is suitable.
Which format should I choose if I have trouble swallowing pills?
Look first at the mini-tablet, liquid, and gummy formats in this roundup, then compare their serving directions and ingredient panels. A smaller tablet may preserve a familiar pill routine, while liquid and gummies avoid swallowing a capsule but can differ in flavor, serving volume, and added ingredients. Do not assume gummies provide the same iron amount per serving as capsules; verify the label directly. For liquid products, check measuring directions so the dose is repeatable. If the difficulty swallowing pills is new or persistent, seek medical advice rather than relying only on a format change.
Can I take an iron supplement with my multivitamin or medication?
Possibly, but first check whether the multivitamin already contains iron and compare the combined amount with your clinician’s advice. Iron can affect the absorption of some medicines, and other minerals or products may also influence timing. The product label may provide directions, but a pharmacist can check your specific medication list and suggest a safe schedule. Keep a record of all supplements rather than judging each bottle separately. Do not change prescribed medication timing or dosage without professional guidance.
Is a larger bottle or multi-pack a better choice?
It can be convenient once you know the product, dose, and format suit your routine, but quantity alone does not make a supplement a better fit. Check how many servings the bottle contains, since a stated capsule count may not equal the same number of days. A large supply is less flexible if you are trying iron for the first time, changing your regimen, or monitoring tolerance with a clinician. Store the product as directed and check its expiration date. For a new routine, a manageable supply can make it easier to reassess before committing to more.
Conclusion
Best overall: I’d start with MegaFood Blood Builder for shoppers who want a vegan formula with added nutrients and several format or bottle-size variations. Best value: Amazon Basics Vegan Iron 18 mg is the straightforward pick for someone who wants a lower-dose capsule format, while NOW Supplements Iron 18 mg offers another simple alternative. Best premium: Thorne Iron Bisglycinate suits buyers who prioritize a clearly named chelated form. Best for beginners: NOW’s 18 mg option is a more measured starting point than the 65 mg Nature’s Bounty product, though a clinician should guide supplementation when deficiency is suspected. Best for specific needs: choose MegaFood’s mini tablets or MaryRuth’s liquid if swallowing pills is a barrier, and reserve the higher-dose products for a plan matched to your needs. My main recommendation is to confirm the dose and timing with a healthcare professional rather than selecting by label strength alone.
