BOOST METABOLISM AND ENERGY. Collagen protein is critical to a healthy metabolism. Amino acids such as glycine can boost metabolism and increase energy levels. It also helps in muscle development which burns more calories than fat.
REJUVENATE YOUR SKIN, HAIR AND NAILS NATURALLY. Collagen production declines as we get older, resulting in wrinkles and less elastic skin. Increasing collagen levels can help your skin look firmer, smoother and more youthful. It can also help maintain sleek, shiny hair and stronger nails.
