A capsule format with a stated per-serving amount, which is what makes intake trackable against the iodine upper limit rather than estimated by the spoonful.
A stacked blend rather than a single-ingredient bottle: sea moss sits alongside black seed oil, ashwagandha, ginger, turmeric, burdock and added vitamins C and D3, taken as two capsules a day. Because the label sells the combination, the sea moss share of each serving is not broken out, so this suits wanting one bottle rather than a measured sea moss dose.
Each of the 40 servings is broken out on the label as 1200 mg sea moss, 1200 mg bladderwrack and 225 mg burdock root, with organic, vegan, gluten-free and non-GMO sourcing. Publishing per-serving numbers instead of one blend total is what lets you compare it against another bottle or keep track of iodine intake.
USDA Organic certification plus third-party batch testing, with the two-capsule serving broken out as 500 mg sea moss, 500 mg bladderwrack and 400 mg burdock root across a 60-capsule month. The capsules can also be pulled apart and the powder stirred into food if swallowing them is the sticking point.
The cheapest way into the standard sea moss, bladderwrack and burdock combination at 120 capsules, lab tested and free of gluten, wheat, yeast, milk and artificial sweeteners. The listing does not publish per-serving milligram amounts, so treat it as a way to try the category rather than to track a specific dose.
The same USDA Organic Power By Naturals formula as the single bottle, bought as a two-pack that covers two months. Worth it only once a first bottle has told you the iodine load agrees with you, since sea moss tolerance is usually a first-month question.
