In humans, Astaxanthin is used as an antioxidant supplement, and as such, is 10 times more potent than other carotenoids. It's also thought to be good for the cardiovascular and immune systems. Some research also suggests it can alleviate oxidative stress to the eyes and brain.
Of particular importance is the natural red pigment astaxanthin (ASX) abundant in both salmon and in crustaceans such as shrimp and crab. ASX has a powerful antioxidant effect, and is capable of penetrating the blood-brain barrier, entering the brain, where it acts directly on nerve cells. ASX is also known to have a neuroprotective effect.
