Why supplement?
Marked asPrimarySupporting
Supports thyroid-hormone synthesis
Brown algae, kelp, and kombu carry iodine in a food matrix; follicles still organify iodine into T4 and T3. Species and sea area can make content differ widely. People watching thyroxine feedstock most often match this food iodine from seaweed; kelp and kombu content can differ a great deal by sea area.
Supports the developing brain and basal metabolism
Seaweed food iodine is likewise a structural element of the hormone. Early-childhood brain development and adult heat production both rely on follicles making iodine into T4 and T3. Coastal diets have more seaweed; inland diets without iodization more often show this feedstock gap, and inland diets without iodization more often expose a feedstock gap.

What to watch
Cautions
