Custom Collagen is one of the original collagen companies and an industry leader with over 40 years of experience with collagen products. Collagen naturally contains 18 essential amino acids and is packed with 10 grams of protein per serving. As early as age 25, our body’s natural collagen production starts to decrease. Taking a collagen supplement replaces that lost collagen. You will look and feel younger as collagen is known for decreasing fine lines and wrinkles, improving joint function and flexibility, and enhancing hair and nail health. Our Beef Collagen Peptides products are made from grass fed, pasture raised cattle and are free from pesticides, hormones, antibiotics, GMO, gluten, soy, and dairy, and is the only certified Clean Collagen® on the market.
