Cholecalciferol (Vitamin D3) - Feed Ingredient

Cholecalciferol, commonly known as Vitamin D3, is a fat-soluble vitamin that plays a crucial role in calcium and phosphorus metabolism. It is synthesized in the skin of horses when exposed to ultraviolet (UV) light from sunlight. In dietary form, cholecalciferol is typically derived from animal-based sources such as fish liver oil or produced via plant sterols

In equine nutrition, Vitamin D3 is essential for bone health, as it facilitates calcium absorption in the intestines and supports skeletal development. Horses with limited access to sunlight, such as those stabled indoors for extended periods, may require dietary supplementation to prevent deficiencies. A deficiency in Vitamin D3 can lead to impaired bone mineralization.

The following equine feeds, supplements and products contain Cholecalciferol (Vitamin D3) as an ingredient.
