Bio-Hoof Nutri-Bites make top dressings a thing of the past with their tasty, apple-flavored supplement. Their formula includes elevated levels of biotin and zinc along with other essential amino acids including methionine and lysine, which work together to provide the essential amino acids and nutrients that your horse needs for strong and hooves and a healthy coat. Biotin is a water soluble B vitamin. This means that it cannot be stored in your horse's body fats, so it must be present in the daily diet. Biotin is necessary because it acts as a co-factor in many of the body's enzymatic reactions. It is essential for the production of fatty acids and proteins. Biotin deficiencies can cause many skin and coat issues, such as dry, scaly skin, lesions, and sparse hair growth. It can also cause brittle, cracking hooves and has been associated with hoof deformities such as dishing and low heels. Zinc is essential for healthy skin. It promotes wound healing and also acts as an astringent. Research has shown that it minimizes hoof abscesses and diseases and can support dramatically improved hoof condition, such as cracking ,infection, and texture. Methionine is an amino acid that must be provided in the diet, some of which is converted into cystine in your horse's tissues. Methionine and cystine both contain sulfur, an element that is essential in the formation of keratin, a fibrous protein that makes up the wall of the hooves. Keratin is made up of sulfur-containing amino acids that, once infused with keratin, become the cells of the hoof wall. The amount of keratin is one of the factors that determines how tough the hoof horn is, and varies in each animal. Nutri-Bites are formulated to promote healing and facilitate high-quality hoof growth. They can be used to address and correct the problems in a horse's hoof, including dishing, toe cracks, white line disease, thrush and many other common problems.
