Collagen levels in our bodies decrease with age, which can cause many of the typical symptoms of aging. NeoCell Super Collagen + Vitamin C & Biotin uses hydrolyzed, grass-fed collagen types 1 and 3 in just three tablets per day to increase your body's production of collagen. Some of the amino acids required by our bodies to produce collagen and other proteins, such as keratin, which is found in our hair and nails, are supplied by hydrolyzed collagen. This non-GMO formula's hydrolyzed, grass-fed collagen has 19 amino acids to support the skin's dermal layers. Biotin promotes healthy hair and nails, and vitamin C helps create collagen and offers antioxidant support.
