Primal Kitchen Collagen Peptides are the perfect supplement to enhance the body’s natural ability to repair joints, tendons and muscles, and to support healthy skin, hair and nails. Unflavored and easily dissolved in hot or cold liquids, Primal Kitchen Collagen Peptides can be conveniently added to your morning coffee, mid-meal shakes or smoothies and baked goods. Collagen is the most abundant protein in the human body, comprising around a quarter of your overall protein makeup and as much as 80% of the protein in your skin alone. Not only does collagen keep skin elastic and hair strong, but it is also critical for the functionality of joints and connective tissue. We source only the highest quality grass-fed collagen and have rigorous heavy metal testing in place to ensure the integrity and quality of our products.
