Analysis

Bladderwrack is a type of seaweed that has been used for a long time to support the thyroid gland. This capsule provides 150 mcg of iodine from a leaf extract, which is the standard daily amount most people need. It is a natural approach to helping your body manage energy through thyroid hormone production.

It is a focused formula with no extra ingredients, which is great if you already take a multivitamin and just want more iodine. The price is reasonable for a two-month supply. This fits well for someone looking for a botanical source of minerals.
