Riboflavin, also known as vitamin B2, is a water-soluble vitamin that is essential for converting carbohydrates, proteins and fats into energy.
Riboflavin is naturally present in the horse’s diet at high levels in alfalfa and clover and slightly lower in grass hays. Riboflavin is also produced by fibre fermentation in the hindgut.
Like with most B vitamins, riboflavin deficiency and toxicity are very rare and have not been reported in horses.
The microbes in a horse’s hindgut are able to synthesize riboflavin, and requirements are easily met with the addition of hay and grain.
Symptomatic riboflavin deficiency is so rare, that signs are not reported in horses even when fed diets that are lacking in this vitamin.
The supplementation of riboflavin and other B vitamins can help to supply optimal levels and allow the horse to perform at its full potential, especially in certain situations.
Horses consuming low-quality hay, those under high stress, on antibiotics or that have compromised hindgut fermentation may require supplements with B-vitamins.
