Astaxanthin is an extremely powerful carotenoid from the microalgae Haematococcus pluvialis, which is one of the richest sources of natural astaxanthin. It is reddish in pigment and it is what gives crustaceans, such as krill, lobster, shrimp, and salmon, their vibrant pink color. Astaxanthin is a uniquely structured, long-chain molecule that enables it to provide superior membrane protection, and it is considered to be substantially stronger than all other well-researched antioxidants. Its impressive antioxidant properties benefit the body in many ways, which include offering support for cardiovascular, gastrointestinal (GI), skin, and eye health.* The astaxanthin in this product is extracted directly from microalgae using a solvent-free technology that ensures maximum control and purity, and allows for optimal bioavailability and stability.
