S.B.
I would be very careful about "free trial offers" you pay the $4.95 and two weeks later they will charge your credit card $79.95 unless you cancel within 2 weeks after receiving product. The terms and conditions are usually hidden. I had to learn the hard way and the only way I got them to credit my account was to threaten legal action and contact the BBB. It might be better to go to a health food store and try it and it will probably be a lot cheaper.
