I swear by this stuff! I don’t take a lot of supplements because I believe you can get most of it through food. But, Vital Proteins will not be going anywhere! This stuff is magic. For those who don’t know what collagen is, it is a protein in the body that is connective to the tissues. Collagen is good for the gut, muscles, hair, skin, and nails- and I can happily say I’ve seen a difference in all those areas. My top favorites are the original collagen and their matcha.
