Astaxanthin is a powerful antioxidant and free radical scavenger. Oxidative stress occurs when the production of harmful molecules called “free radicals” reach levels beyond the normal protective capacity of our antioxidant defenses.
Normally, the body can handle free radicals if enough antioxidants are available, however when we have an abundance of free radicals it may be worth considering increasing our consumption of antioxidants. An antioxidant is a substance that can give an electron to the unstable free radical atom and stop the chain reaction and, in turn, the damage. Well known antioxidants include Vitamins A, C, E, Beta Carotene, and now, the superantioxidant
A randomized double-blind study evaluated Astaxanthin’s effects on oxidative damage to fatty acid membranes, the study concluded that Astaxanthin supplementation lead to significantly reduced oxidized fatty acids. In another study conducted at the Faculty of Pharmaceutical Sciences, University of Tokushima, Japan. Astaxanthin was found to be twice as effective as Beta-Carotene at inhibiting oxidative damage to lipids (that form cell membranes). The study concluded that Astaxanthin’s unique chemical structure makes it a particularly potent tool for trapping free radicals.
