Pegasus Vitamin E and Selenium for horses is a vital addition to the diet of hard-working and athletic horses as well as those who regularly take part in competitions and those with muscle challenges. It supports healthy muscles, muscle recovery and muscle development. It is also a key supplement for breeding and pregnant mares.
Importantly, our supplement contains natural vitamin E which has many advantages over cheaper synthetic vitamin E. Synthetic vitamin E is not absorbed as easily or as completely as the natural version. The bioavailability of naturally-sourced vitamin E is believed to be twice that of synthetic vitamin E. Natural vitamin E also stays in the body longer than the synthetic version.
Selenium is vital to maintain normal, healthy muscle tissue and also to keep red blood cells and the vascular system stable.
Horses whose muscles are regularly being exercised are more vulnerable to tissue damage caused by free radicals attacking membranes and cells. The antioxidant qualities of vitamin E and selenium work in harmony to fight off such attacks. They can interrupt the body's production of free radicals. Hard-working muscles use up more fats for energy - and this increases the risk of tissue damage in a diet limited in vitamin E. Our supplement supports natural immunity and protects the cells of the muscles.
Giving this supplement to a pregnant horse also enables the immunity to be transferred to its foal. Vitamin E and selenium are both vitally important for natural growth and development and fertility and reproduction.
Vitamin E for horses has been shown to support the delivery of a good supply of oxygen to the lungs, and therefore can help performance as well as muscle function. Lack of vitamin E in the diet leads to a much higher risk of muscle damage during exercise, as well as muscle stiffness and soreness and a greater likelihood of succumbing to illness and disease. There is an increased breakdown of cell membranes - including the muscles, heart and brain - when the body does not have access to enough vitamin E.
- Performance and athletic horses
- Horses with high and heavy workloads
- Support muscle health in horses with disturbed muscle function
- Breeding mares - to support the unborn foals natural immunity
- Horses on a high oil diet
- Horses grazing in areas where the soil is naturally low in selenium
Feed at a rate of 25 g per horse per day to supply 1,250 mg of natural vitamin E and 0.5 mg elemental selenium.
25 g = 1,250 mg natural vitamin E
Natural vitamin E has a higher activity than synthetic, so 1 mg of natural gives 1.36 IU of vitamin E activity.
Pegasus Vitamin E & Selenium has 1700 IU of vitamin E activity in a 25 g daily serving.
A 2 kg tub fed at 25 g per day will last 80 days.
Vitamin E for horses was discovered in the early 1920s by two scientists who found that rats could not reproduce on a diet of rancid lard (which is deficient in vitamin E). The scientists found that giving the rats wheatgerm oil solved the problem, and vitamin E was later extracted from wheatgerm oil and given the term ‘tocopherol’ from the Greek meaning ‘childbirth’ and ‘to bear or bring forth’.
As for other vitamins, several different compounds have vitamin E activity, and out of eight compounds (including tocopherols and tocotrienols) only α-tocopherol can meet the body’s vitamin E requirement. Both natural and synthetic forms of α-tocopherol exist, and they have a different chemical structure.
Natural vitamin E is composed of one isomer, RRR α-tocopherol (sometimes called d-α-tocopherol), and is the most biologically active. A stabilized form, RRR α-tocopherol acetate, is used in supplements and feed.
Synthetic forms – widely used in horse feeds and supplements - include all-rac α-tocopheryl acetate and all-rac α-tocopheryl succinate. These forms contain a mixture of eight stereoisomers (slightly different structures), only one of which is RRR α-tocopherol, and thus are not as active as the naturally occurring form. Synthetic vitamin E can be described as dl- α-tocopheryl acetate.
The natural form is more efficiently used in the body and studies have shown increases in plasma α-tocopherol twice that compared to the synthetic form. It could be said that the body ‘prefers it’ to the synthetic forms.
Pegasus Vitamin E & Selenium is manufactured with natural vitamin E.
All types of vitamin E for horses powder are fat-soluble and many oil-based feeds are rich in natural vitamin E. Green plants are also a good source of vitamin E. Processing and storage of feedstuffs, including exposure to heat, light and air causes destruction of vitamin E, and preserved forages cannot be relied upon to supply enough, even if green in colour.
Vitamin E has a variety of biological functions, but the most important is its antioxidant function and it is responsible for the integrity of all body cells.
During the last decade, it has become clear that many horses require higher levels of dietary vitamin E than previously thought, and some researchers believe that in the future, recommendations for daily intake will rise again – particularly for horses in heavy exercise. Nutritionists tend to recommend higher levels than published requirements for breeding horses, those in hard work and those with muscle function challenges.
Horses are often fed selenium along with vitamin E and when its functions are studied, it is easily seen why. Selenium, a micromineral or trace element, is a component of one of the most important antioxidant compounds in the body, glutathione peroxide. Healthy skeletal muscle, heart and liver function depend on adequate dietary selenium, as well as optimal fertility and immune function. Selenium also has a role in thyroid hormone metabolism.
Most UK pasture grass, hay and haylage is deficient in selenium for horses, so it must be supplemented for optimal health. 2 to 5 mg daily is the recommended intake for a typical 500 kg horse, and the maximum tolerable level is 20 mg daily.
Hard working and athletic horses who need extra muscle support benefit from vitamin E and selenium supplementation. Together, these powerful antioxidants can reduce the severity of exercise-induced free radical damage to muscle cells.
Passive transfer of immunity from mare to foal has been shown to be enhanced with the supplementation of vitamin E and selenium during the final three months of gestation.
Selenium supplement for horses is available through inorganic or organic sources, including selenium-enriched yeast. The latter is more bioavailable and has been found in some research studies to be more effective in raising blood selenium levels.
