Vitamin A Supplement - Feed Ingredient

Vitamin A supplement is an essential feed additive used to support vision, immune function, reproduction, and cellular growth in horses. Vitamin A is a fat-soluble vitamin that is commonly provided in the form of retinyl acetate and retinyl palmitate. Since horses and other animals cannot synthesize vitamin A on their own, supplementation is necessary, especially when access to fresh forage is limited.

Commercial vitamin A supplements are typically produced through chemical synthesis or extracted from natural sources such as fish liver oil.

In horses, vitamin A plays a crucial role in maintaining eye health, supporting epithelial tissue integrity, and aiding immune function. Deficiency can lead to night blindness, rough skin, and increased susceptibility to infections. However, excessive supplementation can be toxic, leading to symptoms such as bone abnormalities and liver damage.

The following equine feeds, supplements and products contain Vitamin A Supplement as an ingredient.
