Vitamin E for horses – a fat soluble vitamin - is one of the body’s most important antioxidants, which is vital for the integrity of cell membranes. It traps reactive oxygen species, neutralizing free radicals, and is especially important for healthy muscle and nerve cells. It is also important for the function of the gonads (the testes and the ovaries) so it is vital for reproduction. Vitamin E is also involved in growth and repair of body tissues and in immune function.
The richest source of vitamin E in the horse’s diet is fresh green pasture, and levels are depleted in hay and haylage. Many compound feeds supply suboptimal levels of vitamin E so it should be supplemented where a horse has restricted access to fresh green pasture, and when their requirements are high e.g. hard work and breeding.
Equestrizone's Vitamin E 2000 has been formulated to provide the extra vitamin E required by horses in a variety of situations; most commonly hard working horses, breeding stock and those without access to green forage. The vitamin E our supplement contains is natural, which has many advantages over cheaper synthetic vitamin E. Synthetic vitamin E is not absorbed as easily or as completely as natural vitamin E. 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 synthetic vitamin E.
Natural vitamin E has a higher activity than synthetic, so 1 mg of natural gives 1.36 IU of vitamin E activity. Equestrizone Vitamin E 2000 therefore has 2720 IU of vitamin E activity in a 48 g daily serving.
Performance horses on limited turnout and overweight horses or ponies (or those prone to gaining weight) who have their grass intake restricted will benefit from Equestrizone Vitamin E 2000, replacing the vitamin E they are not getting from fresh green grass.
The body tissues of hard-working horses undergo cycles of microdamage and repair and produce higher levels of pro-oxidant free radicals compared to those of resting horses or those in light work. Working horses need higher levels of antioxidants to support musculoskeletal, respiratory and cardiovascular health, and Equestrizone Vitamin E 2000 is ideal for this purpose.
The natural Vitamin E in our Vitamin E 2000 is mixed with a pure dextrose base, making it easy-to-feed and very palatable. It can be added on top of Pegavite® for horses and ponies on less than the full recommended amount of compound feed.

48g (3 x 25 ml scoops) = 2000mg Equestrizone natural vitamin E
For Natural Vitamin E (3a700 RRR-alpha-tocopheryl acetate), 1 mg = 1.36 IU so:
48g = 2,720 IU of vitamin E activity

Natural source 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 powder for horses 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.
Equestrizone Vitamin E 2000 is manufactured with natural vitamin E.
All types of vitamin E 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.
