Vitamin E is extremely important for muscle and nerve functions in the horse. Horses have a large muscle mass that is asked to do an extra ordinary amount of work in many athletic activities.
There is Vitamin E in many feed stuffs but it rapidly deteriorates after harvest. There are specific conditions that have been described that are related to a Vitamin E deficiency both in muscle and nerve function. When a Horse exercises the requirement for Vitamin E increases many fold.
Stamina Plus has studied these requirements at it Research Facility in Cody, Wyoming and includes the necessary levels for your horse in its Supplements. In the last ten years Research has shown that the requirement for Vitamin E has increased 5 fold.
