The key to healthy skin, lustrous hair, and strong nails is to build them from the inside out utilizing key nutrients. The Hair, Skin, and Nails (RF), is designed to help support healthy hair, skin, and nails by providing the widest range of essential nutrients including vitamins, minerals, and amino acids. The body then incorporates these nutrients in a series of complex biochemical and physiological processes which result in healthier hair, skin, and nails. The true strength and quality of the hair, skin, and nails is built from inside the body out. Hair, Skin, and Nails (RF) helps support the production of specialized proteins such as collagen, elastin, and keratin: all important structural components. Included in the formulation are vitamin C, copper, and zinc, which are all essential for the synthesis and repair of collagen: important for healthy, strong, vibrant skin. Zinc has been shown to be helpful for cell growth, repair, and function, particularly in the cells of the skin. This formulation is rich in sulfur-containing ingredients, such as MSM, Lcysteine, and methionine; all of which help contribute to the strength and stability of the underlying structure of hair, skin, nails, and other body tissue. Important in the formulation is biotin, one of the B-complex vitamins, essential for the metabolism of fatty acids, nutrients necessary for maintaining healthy hair and soft, moist skin. Hair, Skin, and Nails (RF) contains powerful antioxidants vitamins C and E and the mineral selenium, all of which help protect the skin against harmful UV light damage and other sources of oxidative or free radical damage. Finally, this formulation contains Horsetail extract, which provides silicon, an important structural component of skin, hair, and nails. Hair, Skin, and Nails (RF) may be a useful dietary adjunct for individuals who wish to support healthy hair, skin, and nails.
