Most effective form of Glucosamine Sulfate I have tried

Posted by Reviewer2284171 on Jun 23, 2009

Natural Factors Glucosamine Sulfate is the most effective form of this product I've ever used. My sacrum "went out" several years ago and after many chiropractic adjustments was still sensitive and I had to be very careful how I sat and what I sat on. After taking Natural Factors Glucosamine Sulfate, my sacrum feels stronger and does not slip out of alignment. I have tried other brands, but Natural Factors seems to go right to work quickly. iHerb.com is highly reliable and fast at getting your order to you. I will definitely be ordering from them again.
