Bladderwrack is a natural form of iodine. This supplement is great for thyroid health.

It has a the california prop 65 warning, which i did not feel was safe to use. The capsules are pretty thick also, so if you can't take thick pills, these are not for you.

My hands and fingers loosen up and i could play guitar better than i ever have. Great to include in an anti-inflammatory arsenal. My standby for pain.
