Fucus Vesiculosus
Fucus vesiculosus is a brown seaweed that’s rich in iodine, polysaccharides (such as fucoidan), alginic acid, and various minerals. These compounds support thyroid hormone function, have antioxidant effects (protecting cells from oxidative stress), and may benefit skin by improving elasticity and reducing thickness with topical use. Some human studies also suggest that dietary intake can lengthen menstrual cycles and alter hormone levels (lowering estrogen and increasing progesterone) in pre-menopausal women.
