Solgar North Atlantic Kelp Tablets Review

Kelp is derived from the sea. It is a naturally rich source of iodine, which is an essential component of the thyroid hormone that plays a role in growth, development and control of metabolic rate. The iodine from Kelp helps to support healthy thyroid hormone levels. Thyroid hormone also helps regulate the function of mitochondria, which are the energy-producing components of cells.
