Collagen is the "glue" that helps hold our joints and tendons together and gives skin its strength and elasticity; it's found in abundance in our muscles, bones, skin, blood vessels, digestive system and tendons. As we age, our body's natural production of collagen slows down and other lifestyle factors (such as a diet high in sugar, smoking or sun exposure) can further deplete the collagen levels in the body. Adding collagen powder to a smoothie is a good way to boost your collagen intake, but it's also a great way to get some extra protein in your diet. Two scoops provide an additional 18 grams of protein, and the powder easily mixes into smoothies, coffee or even baked goods, making this a simple way to improve skin quality, digestion and athletic performance and recovery.
