Sea Moss Gummies: What a Serving Actually Delivers (2026)
Not medical advice. This summarizes the labels manufacturers file with the NIH, what Amazon listings claim, and current Amazon prices. Sea moss has no clinical trial behind it in any form; see the dosage guide for why.
Quick answer
A sea moss gummy delivers tens of milligrams of extract, not thousands. On every NIH label that states both numbers, the “Irish Sea Moss 1,750 mg” headline row sits above a nested “Irish Sea Moss Extract 87.5 mg” row: a 20:1 equivalent. The “3,000 mg” on the front is the raw-seaweed weight three extracts are said to stand for, per two gummies, with 2 to 4 g of sugar.
There is no studied dose to reach, so the questions are what the panel states and what it costs. Across the 64 Amazon listings we read, 82.8% add burdock, 37.5% are “N-in-1” blends, 14.1% claim third-party testing, and only 10.9% explain that their milligrams are an equivalent. The gummy we pick, Vitamatic Sea Moss Gummies with Bladderwrack & Burdock, states 87.5 mg of extract on its NIH label for $0.33 a serving. See the labels →

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.
Amounts are what each product’s NIH label or Amazon listing declares for the Supplement Facts serving; where the label carries a raw-equivalent headline, the table shows the extract row underneath it. Prices are the current Amazon price for the exact container. Cheapest serving first.

 Bucklebury Wild Crafted Irish Sea Moss Gummies | $0.93 | 87.5 mg extract / 2 gummies (NIH label) | 1,750 mg headline (20:1) | 30 | $27.99 | Amazon |
Two products sit at the top for different reasons. Vitamatic Sea Moss Gummies with Bladderwrack & Burdock is the cheapest serving and the only one whose NIH label we could read row by row: 87.5 mg of extract behind a 1,750 mg headline. Secret Element Sea Moss Gummies 65 mg prints 65 mg of sea moss per serving on the listing itself, with no equivalent arithmetic and no added sugar. Irish Sea Moss Capsules appears below as the capsule comparison.
Every sea moss gummy label filed with the NIH: 7 labels, one pattern
Original research The NIH Dietary Supplement Label Database holds 7 sea moss gummy labels on the market (0 declare any mineral row; 0 declare iodine), against 64 sea moss gummy listings on Amazon. Too few labels exist for a validated census, so the table below prints the labels themselves, as facts, and the shelf statistics come from the listing census further down.
| Label | Serving | Headline row | Extract row | Ratio | Sugars |
|---|---|---|---|---|---|
| Country Farms NIH 329294 | 2 Gummy(ies) × 1/day | Irish Sea Moss 2,000 mg | Irish Sea Moss Extract 100 mg | 20:1 | 4 g |
| Double Wood Supplements NIH 315694 | 2 Gummy(ies) × 1/day | Irish Sea Moss 1,750 mg | Irish Sea Moss Extract 87.5 mg | 20:1 | 3 g |
| Bucklebury NIH 331446 | 2 Gummy(ies) × 1/day | Irish Sea Moss 1,750 mg | Irish Sea Moss Extract 87.5 mg | 20:1 | 3 g |
| Vitamatic NIH 283079 · front says 3,000 mg | 2 Gummy(ies) × 1/day | Irish Sea Moss 1,750 mg | Irish Sea Moss Extract 87.5 mg | 20:1 | 3 g |
| Infinite Age NIH 336560 · front says 3,000 mg | 2 Gummy(ies) × 1/day | none (extract only) | Irish Sea Moss Extract 87.5 mg | not declared | |
| Atlantic Naturals NIH 333818 | 2 Gummy(ies) × 1/day | none (extract only) | Irish Moss Extract 50 mg | 3 g | |
| Nutriissa NIH 310218 · front says 2,840 mg | 2 Vegan Gummy(ies) × 1/day | Irish Sea Moss 1,600 mg | no extract row | 2 g |
All 4 labels that print both numbers use the same 20:1 relationship. Country Farms (NIH 329294) lists Irish sea moss 2,000 mg over an extract row of 100 mg; Bucklebury (NIH 331446) lists 1,750 mg over 87.5 mg, and the two labels that skip the headline simply declare the extract. The extract per two-gummy serving runs from 50 to 100 mg across the 7; sugars run 2 to 4 g. The arithmetic is the same one this site’s magnesium gummies page found for “600 mg” citrate: the front quotes the bigger number, the panel holds the smaller one, and both are technically true.
Why it is built this way is the mass budget. A gummy weighs two to three grams, most of it pectin, sugar and water; a gram or more of dried seaweed powder would not gel, so manufacturers use a concentrated extract and print the seaweed it came from. That is legitimate labelling, but it means a “3,000 mg” gummy and the 1,200 mg-of-powder capsule we track are not the same product at different prices; they are different products.
We read 64 Amazon listings: what sea moss gummies claim
Because the NIH database is thin, the shelf statistics come from Amazon itself: the first three result pages for eight sea moss gummy searches, deduplicated by ASIN and filtered to gummies sold as sea moss (64 listings, 47 brands), each classified by regex on the title and feature bullets. Every figure below was recomputed in two halves split by ASIN parity and only figures that agreed within tolerance are printed.
| Item | Value (%) |
|---|---|
| Adds burdock root | 82.8% |
| Vegan / pectin stated | 76.6% |
| "N-in-1" blend | 37.5% |
| Third-party testing claimed | 14.1% |
| Explains mg as an equivalent | 10.9% |
| "3000 mg" in the title | 9.4% |
| "92 minerals" claim | 6.2% |
The typical listing is a 2-gummy serving from a 60-count bottle at about $22.99. Among listings that state a milligram figure for sea moss, 71.4% claim at least 500 mg and 28.6% claim less; the labels above show that a claim in the thousands is an equivalent and a claim in the tens is the extract, which is why the two groups exist. Only 10.9% of listings say so. “92 minerals” appears on 6.2% of listings; no label we read declares more than the three botanicals and the sugar.
How we read the listings and the labels, and what did not hold
Method: 64 listings retrieved from Amazon.com search results through the Creators API on 2026-09-21 (queries: sea moss gummies; irish sea moss gummies; sea moss bladderwrack burdock gummies; organic sea moss gummies; sea moss gummies for kids; sea moss gummies 3000mg; sea moss gummy vitamins; sea moss elderberry gummies), deduplicated by ASIN and kept only when the title names sea moss or Irish moss and a gummy or chew; each classified by regular expressions over the title and feature bullets. A listing census measures what sellers claim, not what a gummy contains. Every figure was recomputed in two halves split by ASIN parity: 12 of 21 checks agreed (shares within 8 points, medians within 25%); only those are printed. Not printed (9): bladderwrack_pct, iodine_stated_pct, sugar_free_pct, kids_line_pct, vitamin_added_pct, declared_mg_pct, median_declared_mg, at_least_hi_pct, two_plus_gummies_pct. The 7 NIH labels were enumerated from the NIH Dietary Supplement Label Database by paging its ranked search for sea moss gummy terms and keeping labels whose filed physical state is “Gummy or Jelly” and whose panel carries a sea moss row; with 7 labels no split-half statistic is possible, so they are printed label by label and no share is claimed for them. The data is published as open data at /sea-moss/gummies.json (CC BY 4.0). What it cannot tell you: the iodine content of any product, whether the gummy matches its label, or anything about brands that have not filed with the NIH.
Gummy vs capsule: the honest comparison
The capsule we rank on the best sea moss page, Irish Sea Moss Capsules, delivers 1,200 mg of sea moss powder per 2 capsules for $0.22 a serving (90 servings at $19.95). The gummy we pick costs $0.33 a serving for 87.5 mg of a 20:1 extract, which its label equates to 1,750 mg of seaweed. Taken at face value the gummy delivers more seaweed-equivalent per serving at 1.5× the price; taken literally it delivers a few dozen milligrams of extract plus 3 g of sugar. Neither number has a trial behind it.
Who a sea moss gummy makes sense for
A gummy suits someone who will not swallow capsules or make gel, who wants a small daily amount rather than grams of seaweed, and who reads the panel: choose one that states an extract or per-serving amount (Secret Element Sea Moss Gummies 65 mg and Vitamatic Sea Moss Gummies with Bladderwrack & Burdock both do), count the sugar (2 to 4 g per serving on the labels we read) as a small sweet, and treat “92 minerals” as marketing. Several listings are labelled for children 4 and up; a child’s dose of any seaweed product is a clinician’s call because iodine tolerable limits for children are far below the adult 1,100 mcg.
A gummy does not suit anyone trying to reach a “dose” of sea moss, because none exists in the literature, or anyone who wants a known iodine intake: 0 of 7 labels declare it, the iodine in red seaweed varies by species, region and season (PMID 32803579; PMID 29548461), and commercial seaweed products almost never print a number (PMID 28231201). Anyone with a thyroid condition, on thyroid medication, or pregnant should read the safety page first. The small extract amount in a gummy is, if anything, the format’s point in its favour on iodine.
Frequently asked questions
How much sea moss is in a sea moss gummy?
Less than the front of the bottle suggests. On the NIH labels we read, a two-gummy serving carries 50 to 100 mg of sea moss extract; the "1,750 mg", "2,000 mg" or "3,000 mg" on the front is the weight of raw seaweed that extract is said to be equivalent to (a 20:1 ratio on every label that states both numbers). Read the Supplement Facts panel for the row that says "extract".
What does "3000 mg" mean on a sea moss gummy?
On the labels that spell it out, it is the sum of raw-herb equivalents for three ingredients, not the amount in the gummy. Vitamatic's label (NIH 283079) says "3,000 mg" on the front and lists 1,750 mg Irish sea moss, of which 87.5 mg is the extract, plus bladderwrack and burdock, per two gummies. 10.9% of the 64 Amazon listings we read use "equivalent" or ratio wording; most just print the big number.
Do sea moss gummies contain iodine?
Seaweed does, but no sea moss gummy label we read declares an iodine amount: 0 of 7 NIH labels list iodine (0 list any mineral row at all). The iodine in red seaweed varies by species, harvest and processing, and the adult upper limit is 1,100 mcg a day. A 20:1 extract at 50-100 mg is a small amount of seaweed, which is the one reassuring thing about the format, but "92 minerals" is a claim, not a panel.
Are sea moss gummies as good as sea moss gel or capsules?
They are a different product. A capsule or gel delivers raw sea moss by the gram; a gummy delivers a few dozen milligrams of an extract plus 2 to 4 grams of sugar. Per serving the gummy we rank costs 1.5x the capsule we track. There is no clinical trial of sea moss in any form, so neither has a studied dose to reach; what you can check is that the panel states an extract amount and that the sugar suits you.
Which sea moss gummies are best?
Vitamatic Sea Moss Gummies with Bladderwrack & Burdock: 87.5 mg of sea moss extract per 2 gummies on its NIH label, the lowest cost per serving of the gummies we track at $0.33. Secret Element Sea Moss Gummies 65 mg states 65 mg of sea moss per serving on the listing with no equivalent claim and no added sugar, at $0.33 a serving.
