Been using collagen for over a year now, tried over a half a dozen different ones, that all say this and that. Decided to do some homework and really start looking into what our bodies needed vs what these companies were saying/offering. It's pretty simple, so once I figured that out, I tried a couple basic brands and I have been using this one brand for about 3 months now. LOVE IT!!!! I use it in my coffee every morning. No taste, no clumps, no monthly subscriptions, no change in price, you can purchase it just about anywhere & best of all.....it has only the things your body "REALLY' needs each day & isn't full of a bunch of other crap that you either don't need or will get you hooked on buying it over and over again. I will not only buy again when I run out but would gladly recommend to my friends and family.
