By the time you reach 25, your body naturally begins to lose collagen-the super-protein that makes up more than 75% of your skin, hair, nails, bones, and muscles. As these natural gatekeepers of hydration, structure, and elasticity decline, you may start to notice dark circles and thinning hair. Chocolate Milk Collagen is rich, creamy, and reminiscent of a classic hot chocolate, only with a twist and at a fraction of the sugar amount. Mix it with hot milk for a cozy treat or with ice-cold water for a refreshing chocolate milk.
