Now with 5 full milligrams of natural Astaxanthin and augmented by our exclusive carotenoid co-factor blend (featuring Organic Spirulina, Lutein and Lycopene), Purity's new Asta FX Plus -- delivers 25% more Astaxanthin -- than our regular AstaFX formulation. Astaxanthin, a natural carotenoid that gives wild salmon its appealing orange color, is poised to become the next "Superstar Antioxidant." A close relative of the more familiar Beta Carotene and Lutein, Astaxanthin is vastly more powerful at knocking out free radicals! Astaxanthin has been heralded for its benefits for muscle endurance, visual acuity, skin health, immune function and cardiovascular health. Astaxanthin is superior to many other antioxidants, including Vitamin C! An increasing body of research shows how Astaxanthin can be used to support skin health, vision, cardiovascular health and many other important areas of health.* Astaxanthin helps shield fatty components of cell membranes from oxidation (referred to as "lipid peroxidation"). This important property makes Astaxanthin a highly beneficial carotene for cardiovascular health, which relies on maintenance of healthy cell membranes. Astaxanthin is especially effective at neutralizing "singlet oxygen," a reactive form of oxygen raises oxidative stress in the system.* Over two decades of research have yielded a wealth of scientific data about the role of Astaxanthin in supporting the eyes and vision, skin health and physical endurance. While protecting the retina from oxidative stress, studies show Astaxanthin can help support visual accommodation, the ability of the eye to refocus on objects at different distances. Astaxanthin also seems to help reduce everyday visual fatigue from computer use. The skin enjoys benefits from Astaxanthin's protective effect; Astaxanthin helps skin resist the impact of UV light and maintain its youthful qualities and elasticity. Astaxanthin has scientifically demonstrated applications in sports nutrition as well.
