A friend told me Astaxanthin is 6,000x more potent than Vitamin C, stops chelation of metals in the brain and helps skin ageing; so thought I should look into this antioxidant.

NIH study I mentioned where Astaxanthin inhibits collagenases; potent antiwrinkle and antioxidant effect; and UV-induced immunosuppression
