These contain mostly collagen protein, which is an incomplete protein, meaning they don't have all the amino acids we need. And it's just not absorbed well. Therefore you won't really get much protein out of them. They are a very poor choice for a protein supplement.
(indicates that they have used the product)It comes in 2 flavors..Blue Raspberry (I like better)and Fruit Punch. 25gms of protein, 100 cals in 3 ozs, easy to finish quickly. It is kind of syrupy but is sugar and fat free. I take 1 vial to work each night and it is almost half of my daily req
They usually go fast at my local vitamin shoppe..but I order them online now.
