I hear and read about supplements every day. This article from Natural News I read a while back, ordered the product and I have to say am enjoying the benefits. At the bottom of the article is an ebook to download which gives you all the information regarding the benefits of Astaxanthin you would ever want to know. If you got to http://www.vitacost.com/ the product is very affordable and one I would recommend.
