Vitamins

Vitamins are organic compounds required in small amounts to support various physiological functions in horses. They are classified into two categories: fat-soluble vitamins (A, D, E, and K) and water-soluble vitamins (B-complex vitamins and vitamin C). Each vitamin plays a distinct role in metabolism, growth, immune function, and overall health.

Horses typically obtain vitamins from fresh forages, but they are often added to feeds and supplement formulations to ensure adequate intake when horses are consuming preserved forages such as hay.

The following equine feeds, supplements and products contain Vitamins as an ingredient.
