CAS No.: 472-61-7 Molecular formula: C40H52O4 Molecular weight: 596.86 Molecular Structure: Product Specification: 1%, 2%, 3% Astaxanthin Powder 5% Natural Astaxanthin Oleoresin Product Introduction Astaxanthin, a member of the carotenoid family, is an oxygenated red-orange pigment. Professor Basil Weedon was the first to map the structure of astaxanthin. Astaxanthin is found in microalgae, yeast, salmon, trout, shrimp, crustaceans, and other sources. However, Haematococcus pluvialis appears to be the best source of astaxanthin. Astaxanthin cannot be synthesized by human and it must be provided in the diet. Astaxanthin has been proven to be one of the most powerful anti-oxidants yet discovered. University study shows Astaxanthin to be up to 550 effective than Vitamin E and 4 times than lutein in various antioxidant capacities.It freely crosses the blood-brain and blood-retina barriers to provide powerful support for eye and nervous system health. Moreover, increasing evidence suggests that Astaxanthin has extremely useful characteristics in scavenging of active oxygen, immune stimulation, cancer prevention and so on. Preclinical studies demonstrate that astaxanthin is safe and no known side effects. Physiological Functions 1. Powerful antioxidant effects. 2. Increase strength and endurance 3.
