Riboflavin (Vitamin B2) - Feed Ingredient

Vitamin B2, also known as Riboflavin, is a water-soluble vitamin that is essential for energy metabolism in horses. It plays a vital role in the conversion of carbohydrates, fats, and proteins into energy, and is also involved in the maintenance of healthy skin, eyes, and nervous system function.

In equine diets, Vitamin B2 is often supplemented to ensure adequate levels, particularly in horses with increased energy demands or those on a restricted diet. While horses can synthesize some riboflavin in their hindgut, supplementation may be necessary to support optimal health and performance. Vitamin B2 is commonly found in feed ingredients such as alfalfa, green leafy vegetables, and certain grains.

The following equine feeds, supplements and products contain Riboflavin (Vitamin B2) as an ingredient.
