Sea Moss and Iodine

The NIH lists the recommended iodine intake for adults as 150 mcg per day. The adult upper limit is 1,100 mcg per day from all sources, including food, drinks, and supplements.
If you are pregnant, breastfeeding, have thyroid disease, or take thyroid medication, speak with a healthcare professional before using sea moss regularly.
How Much Sea Moss Should You Take?
A common serving size for sea moss gel is 1 to 2 tablespoons per day, but the best serving size depends on the product, your diet, and your health needs.
