How much iodine is in the sea moss?

It varies depending on the batch, but whatever the amount is, it is not the same as taking the same amount as isolated straight iodine drops which is toxic. The iodine in seaweed is bound with other minerals and cofactors, like Algin, that keep it in balance. Normal healthy people usually are fine with a couple spoonfuls of gel daily, but people with THYROID issues should be careful. Sea moss is naturally rich in iodine, which can be helpful for people with Iodine deficiency but for people with autoimmune or overactive thyroid, iodine can make things worse and should be avoided, especially in excess. Sea moss has a moderate amount of iodine so it depends on how much you take. Small amounts are sometimes fine, but each person is different. If you are experiencing throat swelling, then definitely stop! Kelp by the way is usually much higher in iodine than sea moss, so avoid kelp also. Do not take if you have -Hashimoto’s (autoimmune hypothyroid) -Graves’ disease or hyperthyroidism -nodules / goiter -already taking iodine supplements or kelp -on thyroid medication (Levothyroxine, etc.)
