Kelp is high in iodine, which must be present for proper glandular function and metabolism. The thyroid gland depends upon minerals, especially iodine, to function properly and to secrete adequate amounts of thyroxine and triiodothyronine. These hormones influence metabolic rate and body temperature, as well as regulate protein, fat, and carbohydrate utilization in cells. They are also responsible for maintaining growth hormone secretion, the growth of bones, heart rate, force and output; central nervous system health, and helping muscles stay toned and strong.

Kelp is a very rich single source of natural vitamins and minerals, including essential trace minerals. It also contains iron, sodium, phosphorus and calcium, as well as magnesium and potassium. Kelp is a source of vitamins A, B1, B2, C, D and E, plus amino acids. Because kelp's nutrients come in a natural form, they are easily assimilated by the body.
