Learned alot about Astaxanthin this weekend visiting a friends house for the weekend. They own and operate an business that harvest astaxanthin. Becaues of its’ ability to pass the blood brain barrier, it has the ability to have health benefits to nerve tissue that other supplements can not. I encourage all of us to learn more about this incredibly powerful antioxidant. To date, science has not been able to find any known bad effects of taking this supplement. Feel free to read more on Astaxanthin.
