I used to be a big believer in supplementing with fish oils until I started doing some research on the stuff. I found Prof Brian Peskins article on how fish oils are not the all what they are cracked out to be. It made sense, so I decided to buy 3 months supply of YES Peos. I was a bit skeptical but after a month of use I started to feel like I had more energy throughout the day, my skin improved and my hair looked a lot healthier. I now purchase the PEOS on a regular basic and recommend to all my friends.
