Hand-picked Bladderwrack sea vegetable formula enhances metabolic balance. This is the type of seaweed used to enhance the metabolism in type O and modulate the immune system in types O and B. This is a hard to identify species; Dr. D’Adamo uses a trained marine botanist to identify and harvest his. Many “kelp” and “bladder wrack” supplements are not Fucus vesiculosis and are not as effective. Fucus blocks many lectins from attaching to type O cells. Our Fucus product is the highest quality organic freeze dried and unlike the tinctures high in fucose.
