Vitamin E & Selenium play complementary and vital roles in the antioxidant processes throughout the horse's body. Vitamin E is a fat soluble, antioxidant vitamin which plays a vital role in many different functions tin the body, including the immune system, nerves, muscles and reproduction system.
Selenium plays a vital role in the functioning of the immune system and is a key component of a number of selenoproteins. It is an important antioxidant trace element. Working together, Vitamin E and Selenium play important roles in muscle health.
The antioxidant role of these two key micronutrients is especially important in hard working and competition horses and ponies. Oxidation is the process by which fats, carbohydrates and proteins are metabolized to produce energy. However, when this process is accelerated, as energy requirements increase during work, the oxidation process doesn’t differentiate between dietary fats and carbohydrates, and the body’s important structural and functional fats, carbohydrates and proteins, such as cell walls and enzymes, and can begin to break these down also. During the oxidation process, free radicals and other unstable compounds are produced, which further damage cell structures, especially important functional and structural proteins and lipids (fats) in muscle cells.
The role of antioxidants is to either stop the formation of the damaging free radicals, or to deal with them once formed, converting them to harmless substances in the body.
Vitamin E and Selenium play vital and complementary roles in the antioxidant processes throughout the body, helping to protect muscle and other body cells from oxidative damage.
It must be remembered that excessive selenium intake can rapidly become toxic, and the addition of a selenium and vitamin E supplement should be carefully considered, in conjunction with other selenium sources in the diet.
