Astaxanthin and vitamin C work together to promote healthy immune system function and provide powerful antioxidant support. Astaxanthin is one of the most potent antioxidant carotenoids and plays an important role in protecting cells from oxidative damage. Because it can cross the blood-brain and blood-retina barriers, it can deliver antioxidant protection to our eyes, brain, and nervous system. Astaxanthin also supports endurance and health and promotes healthy skin. Vitamin C is a water-soluble antioxidant that helps scavenge free radicals, provides cellular protection, and regenerates other antioxidants. The synergistic blend of astaxanthin and vitamin C offers whole body health benefits and can help support a healthy balance between oxidative stress and antioxidant defense within our body.
