I have been reading lots of research that claims Astaxanthin is 800x more powerful an antioxidant than CoQ10, and that it has great potential benefits for PWPS. The studies indicate that it supports brain function, eye sight and is being studied to treat Alzheimer's as well. This is the stuff that is responsible for the pink coloring found in salmon and krill..and is what flamingos eat that makes them pink. As a side benefit, is is also an internal protection against the effects of sun exposure to skin. I have just begun to try it myself...so far...my skin has not turned pink!
