Sea Moss Gummies: What a Serving Actually Delivers (2026)
Most sea moss gummies hold 50 to 100 mg of sea moss extract, not the 1,750 or 3,000 mg on the front. The best one is MaryRuth’s Sea Moss Gummies: 50 mg of Irish moss with no added sugar, $0.83 a day at the brand’s price. A two-capsule serving holds far more extract for less money.

Why we pick it It names its seaweed, Irish moss (Chondrus crispus), and states 50 mg a serving with no “equivalent” math. It has no added sugar. And the brand says an outside group, the Clean Label Project, certified it after testing for contaminants.
What you give up 50 mg is a small amount: a Double Wood Irish Sea Moss serving holds 1,200 mg of extract for less money. The brand posts no lab numbers and no iodine figure.
Which sea moss gummy is right for you?
Most sea moss gummies add bladderwrack and burdock and some sugar. Read the extract line on the label, not the front.
Want more sea moss per gummy?
Two Bucklebury gummies hold 87.5 mg of Irish moss extract, which the front of the bottle calls 1,750 mg (a 20:1 equivalent), plus bladderwrack and burdock root. Bladderwrack is a brown seaweed, usually higher in iodine. It has 3 g of sugar a serving. The brand says “lab tested” but posts no report.

Want more sea moss for less?
Take a capsule. Two Double Wood capsules hold 1,200 mg of Irish moss extract, with no sugar, and the brand posts a lab report for heavy metals in its batch. It is our pick on the best sea moss page.

Sea moss gummies we compared, ranked
We rank by what the label tells you (the seaweed named, an amount with no equivalent math, sugar), then any testing the brand names, then cost a day at the brand’s own price. All three are 60 gummies, 2 a day.

What the labels really say
The NIH keeps a database of supplement labels, and it holds 7 sea moss gummy labels. 4 of them show the same thing: a big “Irish Sea Moss” number on top, and a much smaller extract amount under it.
| Brand | Top line | Extract | Sugar |
|---|---|---|---|
| Country Farms | 2,000 mg | 100 mg | 4 g |
| Double Wood Supplements | 1,750 mg | 87.5 mg | 3 g |
| Bucklebury | 1,750 mg | 87.5 mg | 3 g |
| Vitamatic | 1,750 mg | 87.5 mg | 3 g |
| Infinite Age | No top line | 87.5 mg | Not listed |
| Atlantic Naturals | No top line | 50 mg | 3 g |
| Nutriissa | 1,600 mg | No extract line | 2 g |
Every label that prints both numbers uses a 20:1 ratio: 87.5 mg of extract is sold as 1,750 mg of sea moss. Not one of the 7 labels lists iodine.
We also read 64 Amazon listings for sea moss gummies (on September 21, 2026). 83% add burdock root, and only 11% say their milligrams are an equivalent.
Iodine and who should skip them
Not one NIH label lists iodine, and none of the 3 we compare posts a number. Many add bladderwrack, a brown seaweed usually higher in iodine. Adults should stay under 1,100 mcg of iodine a day (NIH). Ask your doctor first if you have a thyroid condition, take thyroid medicine, or are pregnant or breastfeeding, and before giving them to a child. More on sea moss safety.
Questions people ask
How much sea moss is in a sea moss gummy?
Less than the front says. On the NIH labels we read, two gummies hold 50 to 100 mg of sea moss extract. The “1,750 mg” or “2,000 mg” is the weight of raw seaweed that extract is said to equal (20:1).
What does "3000 mg" mean on a sea moss gummy?
It is not the amount of sea moss. On Vitamatic’s NIH label, the front says 3,000 mg, but the sea moss line is a 1,750 mg “equivalent” made from 87.5 mg of extract, and its Amazon listing also names bladderwrack and burdock.
Do sea moss gummies contain iodine?
Seaweed always holds some, but none of the 7 NIH labels we read lists an iodine amount. Many gummies add bladderwrack, a brown seaweed usually higher in iodine. Adults should stay under 1,100 mcg a day.
Are sea moss gummies as good as sea moss gel or capsules?
They hold much less. A two-capsule serving holds about 1,200 mg; most gummy servings hold 100 mg or less of extract, plus sugar. No form of sea moss has been tested in people for its claimed benefits.
Which sea moss gummies are best?
MaryRuth’s Sea Moss Gummies. It names its seaweed, has no added sugar, and the brand says it is Clean Label Project certified.
