    The Importance of Vitamin C for Horses Nutrition

    Vitamin C, also known as ascorbic acid, plays a vital role in a horse's body, including antioxidant properties, hormone synthesis, bone calcification, collagen synthesis, and immune system function. Although horses can synthesize vitamin C from glucose within their bodies, under certain conditions such as hot weather, stress, rapid growth, old age, and inflammation, they may require additional vitamin C to meet their needs. Unlike humans, horses cannot store vitamin C in their bodies, so they need a continuous supply of vitamin C. Supplemental sources of vitamin C, such as fresh fruits and vegetables or specific equine supplements, can ensure adequate vitamin C intake in horses under certain circumstances.

    Sources of Vitamin C for Horses

    Hay and grains are not good sources of vitamin C for horses. Hay contains almost no vitamin C because it is unstable when stored. Therefore, horses may require supplemental sources of vitamin C to meet their needs under certain conditions. Fresh fruits and vegetables, such as apples, carrots, and oranges, are excellent sources of vitamin C. However, it is important to feed them in moderation, as excess feeding can lead to digestive upset. Specific equine supplements are also available in the market to ensure adequate vitamin C intake in horses. Careful consideration should be given to the sources of vitamin C to avoid overfeeding and ensure optimal health for horses.
