Opti-Coat is a nutritional equine supplement that includes high concentrations of fatty acids, biotin, selenium, and vitamin E in a highly palatable liquid form. It provides the key nutrients for the growth of healthy, lustrous hair, mane and tail. The sebum stimulates the skin oils where each hair is coated, causing them to lay flat and giving them shine and luster. Sufficient sebum is necessary to help lubricate the skin, forming an oily protective barrier, which also inhibits the growth of harmful microorganisms. The stimulation of sebum can be done by brushing, but most importantly by the addition of the key nutrients in the horses diet. Opti-Coat supplies these nutrients.
