By the time you reach 25, your body begins to lose collagen-the super-protein that makes up over 75% of your skin, hair, nails, bones, and muscles. As collagen declines, you may start to notice wrinkles, dark circles, and thinning hair. This Korean Collagen Broth has all of the flavor and nutrients of real fish stock, without any of the hard work, and it can be used as a base for comforting Korean dishes or enjoyed by itself as a flavorful, protein-packed soup.
