Yes, however...: "normal" levels often aren't optimal levels. Many people have trouble converting T4 to T3 (liothyronine) & thus need T3 (liothyronine) too. Please ask your doctor to check free T3 (liothyronine) (& ideally reverse t3). People may not feel good until T3 (liothyronine) is in the upper half of the normal range. If your dr. Won't prescribe it, find one who will! kelp is ok but may not be enough. See http://www.Stopthethyroidmadness.Com/t4-only-meds-dont-work/.

Controversial answer... T3 levels vary widely. Kelp is not likely to help.

No kelp: The most common cause of hypothyroidism in developed countries is hashimotos thyroiditis. Taking iodine, as in kelp, makes this worse. There is a small percentage of people with hypothyroidism that feel better on T3 (liothyronine) (due to decreased T4 to T3 (liothyronine) conversion in the brain, not elsewhere). Taking T3 (liothyronine) will not help you lose weight any better. You need to eat less and exercise to lose weight.
