Hello! I am a mom of two sons, 20 and 22 years old in great health. I am an avid health enthusiast and I've been studying health for at least 20 years, trying different supplements and learning from naturopathic and holistic doctors as well as allopaths. I also work in the health area as a medical secretary for many years. I know what works and I think I can help you make the right decision on which supplement to buy from iherb. I've been buying from iherb for years and they just get better and better!
