Fun fact – the way we keep our horse these days can contribute towards deficiencies in fat soluble vitamins. This is very common. Here is some recent research that confirms:

Vitamin A: Up to 85% of horses can be deficient in vitamin A during winter and spring, especially if they don’t have access to fresh pasture and are fed on stored or poor-quality hay. (https://bit.ly/4cPT5Du)

Vitamin D: Horses that don’t graze-like many stabled or racehorses-are much more likely to have low vitamin D levels. Unlike humans, horses can’t make vitamin D from sunlight and must get it from their diet, mainly through grazing. Horses without pasture access often need supplements to meet their needs.

Vitamin E: About 1 in 6 horses (16.5% of adults) admitted to veterinary hospitals are found to be deficient in vitamin E. This deficiency is more common in adults than foals, and horses fed stored feeds are at higher risk. (https://bit.ly/4m82jPY)

This is the reason we add these three fat soluble vitamins (and others) to Ultimate mix, the ultimate all-round supplement.
