Morning Ning~
I did google Ancient Nutrition...I'm impressed with the ingredients and price. The fact that they do make an unflavored type is interesting to me. It's a bit more expensive than the Coreage...with approx. 18 more grms per container. It also contains all 5 of the same 'types' as Coreage. There are many of these Collagens out there now...I've tried a few..my problem is that I like to use it in my coffee and some of these just don't dissolve well..which wouldn't be a problem in a smoothie. If you've tried this brand..let us all know what you think...much appreciated! Good health to us all!
