I recommend Nutrii Collagen Grass Fed Hydrolyzed Peptides
Since I started taking this Collagen, I have experienced great improvement with the pain on my knee.  My hair is soft and getting thicker which is why I tried the product to begin with.  I have also noticed weight loss since I am not eating constantly.  I have just completed my third bottle and I can see significant changes with my hair, skin and weight.  It is worth the money and I definitely recommend it because it works.
