Fucus vesiculosus , also known as kelp, is a brown seaweed that has air vesicles that contribute to its buoyancy. This algae is found in Brittany in particular, as well as on the French coast and in the North Sea.
Kelp contains polysaccharides, including 15% alginic acid, as well as laminarin and fucoidin, which have immunostimulant properties. This seaweed also contains minerals (iodine, calcium, potassium, iron, sodium, phosphorus), numerous vitamins and amino acids, including the so-called "essential" ones. Iodine is involved in the proper functioning of thyroid hormones. Consuming iodine can help prevent hypothyroidism.
In addition, the polyphenols in kelp including phlorotanins, are responsible for its antioxidant effect.
- Kelp is a brown seaweed rich in iodine and polysaccharides. Fucoidanes and phlorotanins have antioxidant properties that reduce oxidative stress on the cells.
- The polysaccharides contained in this algae are involved in stimulating the cells of the immune system.
