Andrew Lessman's ASTAXANTHIN is uniquely designed to deliver a pure, concentrated source of natural Astaxanthin, which is perhaps nature's most powerful anti-oxidant carotenoid. Astaxanthin is derived from aquatic algae and it is responsible for the rich reddish-pink color observed in many aquatic species including salmon, crab, lobster, shrimp, krill and even the flamingo, whose diet is abundant in Astaxanthin-producing algae. Astaxanthin-rich foods are principally fish, shellfish and crustaceans who consume Astaxanthin-rich organisms, however Astaxanthin's most pure and plentiful source is the microalgae Haematococcus pluvialis, which is the natural source used to make this product. Astaxanthin has been consumed for centuries, but has only recently gained recognition for its beneficial properties. Recent research indicates Astaxanthin is many times more powerful an anti-oxidant than Beta-Carotene, Lutein, Lycopene and Zeaxanthin, and up to hundreds of times more powerful than Vitamin E! Astaxanthin helps to protect cells and cell membranes from oxidative damage and it can cross the blood-brain barrier enabling it to lend support to the delicate tissues of the nervous system and brain. It also helps to promote the health of the tissues of the eye, enhancing visual acuity and eye function. Astaxanthin's wide-ranging supportive benefits also extend to the heart, liver, breast and immune system. To assure you the greatest benefits possible, we use only the most well-researched, pure, highest quality, contaminant-free source of natural Astaxanthin.
