Iron Gummies: How Much Iron They Deliver vs the RDA (2026)
Not medical advice. This summarizes published trials, NIH intake references, the labels manufacturers file with the NIH, and current Amazon prices. Iron deficiency is diagnosed and treated with a blood test and a clinician; supplement only when you know you are low.
Quick answer
An iron gummy is a maintenance dose, and the label census says exactly how small. On the 15 iron gummy labels filed with the NIH, the median serving delivers 10 mg of elemental iron, 20% of servings reach the 18 mg RDA for menstruating women, and none reaches the 27 mg of pregnancy. Repletion protocols run 60 to 100 mg every other day, 3 to 10 times a gummy serving.
A gummy suits someone filling a gap in a normal diet, not someone treating a deficiency, and every bottle carries the FDA child-poisoning warning for a reason. Across 66 Amazon listings, 50% are sold for kids and 86.4% add vitamin C. Per 18 mg the gummy we pick, Vitamatic Vegan Iron 20 mg with Vitamin C Gummies, costs $0.30, 5.6× the bisglycinate capsule we rank. See the census →

Product links go to Amazon and we may earn a commission if you buy. It never changes which product we pick or what we say about it. How we choose.
Doses are the elemental iron row on each product’s NIH label or listing; prices are the current Amazon price for the exact container. Cost per 18 mg is the price per serving divided by the iron per serving, times 18. Cheapest first.

Vitamatic Vegan Iron 20 mg with Vitamin C Gummies is the cheapest per 18 mg and its NIH label states 20 mg of iron as ferrous fumarate with vitamin C per 2 gummies, at 5 g of sugar a serving. Nature Made Iron 18 mg Gummies with Vitamin C delivers the RDA exactly from a national brand. Lifeable Kids Iron Gummies 10 mg with Vitamin C is the children’s line, 10 mg per 2 gummies; a child’s iron dose is a clinician’s call. The capsule comparison, NOW Foods Iron 36 mg Double Strength, is a single 36 mg bisglycinate capsule for $0.11, twice the RDA in one unit and the form the bisglycinate guide ranks for tolerability.
We read 15 iron gummy labels: what a serving delivers
Original research Every iron gummy label we could enumerate in the NIH Dietary Supplement Label Database on 2026-09-21: 45 labels whose physical form is a gummy or jelly and whose panel carries an iron row, of which 15 are sold as iron (30 prenatal, multivitamin, CBD and other gummies with some iron in them are excluded); all 15 carry an elemental iron quantity per serving. 13,636 iron-containing labels of any form are on the market. It is a small shelf, and the numbers below are read with that in mind.
The median serving delivers 10 mg of elemental iron and the median day the same 10 mg; a quarter of labels deliver 8 mg or less a day. Servings run from 4 to 20 mg. 20% of servings reach 18 mg; none reaches 27 mg, so no gummy label we read covers the pregnancy RDA in one serving. Every label declares a sugars row (100%), and none is sugar-free. 46.7% set their Daily Value column for children 4 and older alongside adults.
| Item | Value ( mg) |
|---|---|
| Gummies, lower quarter | 8 mg |
| Gummies, median day | 10 mg |
| Highest gummy serving | 20 mg |
| RDA, menstruating women | 18 mg |
| RDA, pregnancy | 27 mg |
| Adult upper limit | 45 mg |
| Repletion, low end (alternate days) | 60 mg |
On a shelf of 15 labels the upper quartile, the form shares and the vitamin C pairing did not survive the split-half test and are not printed. What survives is negative: ferrous sulfate, the form with the documented side-effect penalty, appears on none of them.
How we read the labels and the listings, and what did not hold
Method: 45 labels retrieved from the NIH Dietary Supplement Label Database on 2026-09-21 by paging its ranked search for iron gummy terms and keeping only labels whose filed physical state is “Gummy or Jelly” and whose panel carries an iron row; 15 sold as iron were analysed and 15 carried an elemental iron quantity for the Supplement Facts serving (the row named “Iron” is the elemental amount; a row named for a salt is never credited). Daily dose is that quantity multiplied by the label’s maximum daily servings. Every figure was recomputed in two halves of the corpus split by label-id parity: 9 of 24 checks agreed within tolerance; only those are printed. Not printed (15): p75 daily mg; median mg per gummy; share at least 10 mg per serving; share below 10 mg per serving; share at least 18 mg per day; median gummies per day; share directing 3+ gummies/day; form or brand declared share; median sugars g/day (declaring); kids-line share; accidental-overdose warning stated share; bisglycinate share; ferrous fumarate share; ferric / pyrophosphate share; vitamin C paired share. The serving range is an observed extreme, not a validated statistic. The Amazon listing census (66 listings, ASIN-parity split): 16 of 21 held; not printed (5): ferrous_fumarate_pct, for_women_line_pct, gentle_claim_pct, multi_blend_pct, two_plus_gummies_pct. Open data at /iron/gummies.json (CC BY 4.0). What it cannot tell you: how well any gummy’s iron is absorbed, whether the gummy matches its label, or anything about brands that have not filed with the NIH.
The doses that matter, and why a gummy is not a treatment
The NIH references are 8 mg a day for men and post-menopausal women, 18 mg for menstruating women and 27 mg in pregnancy, with a tolerable upper limit of 45 mg a day for adults from all sources; the dosage guide sets them out by age and sex. A gummy serving at the median 10 mg is a top-up for a diet that is nearly there. Repletion is a different arithmetic. Each oral dose of iron raises hepcidin, the hormone that shuts absorption down, for about a day, so daily and twice-daily dosing absorbs a smaller fraction of each dose than it should (PMID 26289639); in two randomized trials in iron-depleted women, giving the same supplement on alternate days raised fractional absorption compared with consecutive days (PMID 29032957). Modern protocols therefore use roughly 60 to 100 mg of elemental iron every other day, which is 6 to 10 median gummy servings at once, with the sugar that comes with them.
Form matters less than dose in a gummy, but ferrous sulfate causes significantly more gastrointestinal side effects than placebo in a systematic review and meta-analysis (PMID 25700159); the gummies we read use ferric pyrophosphate or ferrous fumarate instead, and the sulfate vs bisglycinate comparison covers the chelated form that only 22.7% of listings use.
We read 66 Amazon listings: what iron gummies claim
The first three result pages for eight iron gummy searches, deduplicated by ASIN and filtered to gummies sold as iron (66 listings, 51 brands), classified by regex on the title and bullets, recomputed in two halves by ASIN parity; only figures that held are printed.
| Item | Value (%) |
|---|---|
| Adds vitamin C | 86.4% |
| Sold for kids | 50% |
| Adds B12 or folate | 48.5% |
| Sugar-free | 27.3% |
| Names bisglycinate | 22.7% |
| Third-party testing claimed | 12.1% |
| Mentions the overdose warning | 1.5% |
The typical listing is a 60-count bottle at about $19.99; 62.1% state an iron figure, and among those the median claim is 25 mg with 80.5% at 18 mg or more. The listings run higher than the NIH labels: the median listing claim of 25 mg is above the highest serving on any filed label (20 mg), because the Amazon shelf carries high-dose gummies that have not filed with the NIH. The label census is what has been filed; the listing census is what is being sold; and any gummy serving above 45 mg is above the adult upper limit in one serving.
The child warning on every bottle, in the label’s own words
US law requires a specific warning on iron-containing supplements (21 CFR 101.17(e)), and the labels file it. Lifeable's NIH label (313369) reads: Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. Keep this product out of reach of children. In case of accidental overdose call a doctor or poison control center immediately.
A gummy is the format designed to taste like a sweet, and the 90-gummy bottle of the children’s line we track holds 450 mg of iron. Store it as medicine, not as vitamins on the counter. The NIH upper limit for children is 40 mg a day; a children’s line at 10 mg per serving sits well under it, and a clinician sets any dose beyond food.
Who an iron gummy makes sense for, and who should not buy one
Buy a gummy if your target is the RDA or a fraction of it, you will not swallow a tablet, and you know from a blood test that you are not deficient: a menstruating woman topping up a diet that is nearly there, a vegetarian whose ferritin is fine, a teenager with a clinician’s nod. Choose one that states the elemental milligrams on the panel (Vitamatic Vegan Iron 20 mg with Vitamin C Gummies and Nature Made Iron 18 mg Gummies with Vitamin C both do), take it away from calcium and coffee, and count the 5 g of sugar a serving as a small sweet.
Do not buy a gummy to correct a diagnosed deficiency or anemia: the trial-backed protocols use 60 to 100 mg every other day, the gummy shelf tops out at 20 mg a serving on the NIH labels, and the anemia and low-ferritin guide covers what works. Do not take iron without a test if you are a man or post-menopausal, because iron accumulates. Pregnancy needs 27 mg, which no gummy serving we read supplies; the iron for women page has the options.
Frequently asked questions
How much iron is in an iron gummy?
On the 15 NIH iron gummy labels we read, a serving carries 4 to 20 mg of elemental iron with a median of 10 mg, and the median day is the same 10 mg because most labels direct one serving. 20% of servings reach the 18 mg RDA for menstruating women; none reaches the 27 mg pregnancy RDA. A gummy is a maintenance dose, not a repletion dose.
Can iron gummies treat iron deficiency or anemia?
Not at the doses on the labels. Modern repletion protocols use roughly 60 to 100 mg of elemental iron every other day, because each dose raises hepcidin and blunts absorption of the next; alternate-day dosing absorbed more per dose in iron-depleted women. The largest gummy serving we read was 20 mg. If a blood test shows deficiency, the dosage guide covers capsule and liquid options at repletion doses; treatment is a clinician's call.
Are iron gummies safe around children?
Every iron supplement sold in the US must carry the FDA warning that accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6, and must be kept out of reach. Gummies taste like sweets, which is the whole concern: the 90-gummy bottle of the children's line we track holds 450 mg of iron. 50% of the 66 Amazon listings we read are sold for kids; only 1.5% mention the warning in their listing copy, though it is on the label.
Which form of iron is in gummies?
Mostly not the gentle one. Ferric pyrophosphate and ferrous fumarate dominate the NIH labels we read; on Amazon 22.7% of listings name bisglycinate. 86.4% of listings add vitamin C. Ferrous sulfate, the form with the documented GI side-effect penalty in a meta-analysis, appeared on none of the gummy labels we read.
Which iron gummies are best?
Vitamatic Vegan Iron 20 mg with Vitamin C Gummies: 20 mg of elemental iron per 2 gummies on its NIH label, the cheapest per 18 mg of the gummies we track at $0.30. Nature Made Iron 18 mg Gummies with Vitamin C delivers the 18 mg RDA exactly at $0.50. If you need more than the RDA, the capsule we rank, NOW Foods Iron 36 mg Double Strength, costs $0.05 per 18 mg and $0.11 for its 36 mg capsule.
