Sea Moss & Bladderwrack Supplement 200 Capsules

Wildcrafted Irish sea moss (Chondrus crispus) and bladderwrack (Fucus vesiculosus), two whole-plant sea vegetables in one capsule, known in Spanish as musgo marino irlandes. Each 3-capsule serving delivers 900 mg of Irish moss and 900 mg of bladderwrack, 300 mg of each per capsule. 200 vegetable capsules per tube, about a 2 month supply at 3 per day. Third party tested, no fillers or additives.

What is in it, tested and disclosed

The minerals are the seaweed's own, not added. An independent lab tested a serving in December 2025 and found 561 mcg of naturally occurring iodine (374% of the daily value, still within the NIH adult upper limit of 1,100 mcg per day) and 2 mg of iron (11% of the daily value, a good source of iron). See our full lab results.

Iodine supports normal thyroid function and healthy skin.* Iron supports red blood cell formation and helps reduce tiredness and fatigue.* Sea moss and bladderwrack also naturally provide other minerals, including calcium, magnesium and potassium, which support normal muscle and nerve function.*

Why capsules instead of gel?

No soaking, no blending, no taste, and the same serving every time. Capsules travel well and take seconds, which makes a daily sea moss habit easy to keep.

Quality you can check

The sea moss and bladderwrack are wildcrafted, harvested from the cold North Atlantic, manufactured in the USA, and tested by an independent lab for identity, microbials, and heavy metals. Vegan capsules (vegetable cellulose).

How to take

As a dietary supplement, take 3 capsules daily. Store tightly closed in a dry place at room temperature.

Frequently asked questions

What is sea moss and bladderwrack good for?
They are mineral-rich sea vegetables, not medicines. The minerals are real: iron for red blood cells and iodine, which your thyroid uses.* For the deeper story, read our guides to bladderwrack benefits and sea moss and the thyroid.

How much iodine is in a serving?
561 mcg per 3-capsule serving, confirmed by independent lab testing. That is a high-iodine product, which is why we include the warning below. See our full lab results.

What is the difference between sea moss and bladderwrack?
Sea moss is a red seaweed and bladderwrack is a brown one, and bladderwrack typically runs higher in iodine. They have been paired in Caribbean and Irish tradition for generations, which is why we combine them in one capsule.

When should I take the capsules?
Any time that helps you stay consistent; many people take them in the morning, with or without food. For the morning versus evening breakdown, read our guide to the best time to take sea moss.

Do you sell raw sea moss too?
Yes. If you prefer soaking and blending your own gel at home, we also carry wildcrafted raw sea moss. The capsules are the same whole plant, already measured and ready to take.

Where can I buy sea moss and bladderwrack?
Right here. We ship worldwide, with orders leaving in 1 to 2 business days.

How do I take these capsules?
As a dietary supplement, take 3 capsules daily. Each serving delivers 900 mg each of sea moss and bladderwrack (300 mg of each per capsule). The 200 count bottle is about 67 servings, roughly a 2 month supply.

What nutrients are naturally found in sea moss and bladderwrack?
They naturally contain iodine, iron, calcium, magnesium, potassium, and zinc, along with vitamin C and several B vitamins. The minerals are the seaweeds' own; nothing is added.

Are these capsules vegan, and what else is in them?
Yes. The capsules contain wildcrafted sea moss and bladderwrack in a vegetable cellulose capsule, with no fillers, additives, or mixing agents. Every batch is third party tested for identity, heavy metals, and microbials.

Are these sea moss capsules organic or wildcrafted?
Wildcrafted. Sea moss grows wild in the ocean, so organic certification does not apply to it; ours is harvested by hand from cold Atlantic waters rather than grown on ropes in pools. Every batch is third party tested.

Is 561 mcg of iodine a lot?
It is 374% of the Daily Value, which sounds high but sits well under the adult upper intake level of 1,100 mcg per day set by the NIH. For perspective, published research estimates that in Japan, where seaweed is an everyday food, average iodine intake runs between 1,000 and 3,000 mcg per day. If you have a thyroid condition or take thyroid medication, talk with your healthcare provider before use.

What is sea moss and bladderwrack? Are they the same thing?
No, they are two different sea vegetables. Sea moss (Chondrus crispus), also called Irish moss, is a red seaweed from cold Atlantic waters. Bladderwrack (Fucus vesiculosus) is a brown seaweed from the same coastlines. Both have long histories of traditional use, and this supplement combines them in equal parts.

What are the benefits of sea moss and bladderwrack capsules?
These seaweeds are naturally rich in minerals. Each 3 capsule serving provides 561 mcg of iodine (374% DV) and 2 mg of iron (11% DV). Iodine supports normal thyroid function and healthy skin,* and iron supports red blood cell formation and helps reduce tiredness and fatigue.*

Sea moss gel or capsules, which should I choose?
They are the same seaweed in different forms. Gel is stirred into drinks and food, and you can make it at home from our raw sea moss or our Irish sea moss powder. Capsules hold the dried whole plant, with no soaking, no blending, no taste, and the same measured amount every time.
