Aloha, I'm a geneticist and I'm tangentially interested in supplements and natural living. I've tried about, erm, a gazillion products and most of them I never re-order. But there are several that I have found to work, and work well. So if you're interested in my opinions, please feel free to peruse my reviews and look for items that I have given four- or five-stars — those are the products that actually work and that I order again and again from iHerb. Mahalo nui loa, and aloha!
