Natural Vitamin E
Natural Vitamin E (d-alpha-tocopherol) is a fat-soluble antioxidant that protects cells and tissues from oxidative damage. It supports immune health, muscle recovery, cardiovascular function, and neural integrity in horses. Compared to synthetic dl-alpha-tocopherol, the natural form is significantly more bioavailable and efficiently incorporated into cell membranes, making it the preferred source for supplementation.
Vitamin E is a key component of the body’s antioxidant defense system, neutralizing free radicals produced during metabolism and exercise. It helps maintain the integrity of muscle and nerve tissues, supports red blood cell stability, and reduces oxidative stress associated with intense training or illness. Chronic deficiency can lead to neuromuscular disorders such as equine motor neuron disease or vitamin E–deficient myopathy.
Fresh green pasture is the richest natural source of vitamin E, but levels decline rapidly during hay storage and are negligible in most grains. Horses without regular access to pasture, those in heavy work, or individuals with metabolic conditions benefit from daily supplementation of natural vitamin E to maintain optimal antioxidant status and support recovery.
Supplementing bioavailable natural forms of vitamin E has been shown to enhance immune response, improve muscle enzyme stability, and reduce inflammation following exercise, contributing to overall vitality and performance in horses.
Consult with a nutritionist or veterinarian prior to use.

Frequently Asked Questions
Vitamin E is a powerful antioxidant that protects cells from oxidative damage. It supports muscle health, immune function, nerve tissue, recovery, and overall well-being. Adequate Vitamin E intake helps maintain muscle integrity, strengthens the immune system, and supports horses in heavy training, on hay-only diets, or with metabolic or neurological concerns.
Horses most at risk of Vitamin E deficiency include those on hay-only diets with little or no fresh pasture, horses in heavy training, broodmares, growing horses, seniors, and horses with neurological disease or chronic immune challenges. Horses with restricted pasture access or metabolic conditions may also benefit from additional supplementation. A blood test is the best way to determine if your horse requires more Vitamin E.
Signs of low Vitamin E status may include poor muscle development, muscle soreness, impaired coordination, dull coat, reduced immunity, and slower recovery after exercise. Severe deficiencies may result in neurological problems. Because these signs can overlap with other conditions, blood testing is the most reliable way to confirm deficiency.
Fresh green pasture is the richest natural source of Vitamin E. However, levels decline rapidly once forage is cut and dried. Horses on hay or with limited pasture may not receive enough Vitamin E from forage alone. Supplementing with a natural, bioavailable source such as Mad Barn’s Natural Vitamin E (d-alpha-tocopherol) ensures horses meet their daily requirements.
Mad Barn’s Vitamin E is the natural form, known as d-alpha-tocopherol. This form is identical to the Vitamin E found in plants and is used more efficiently by the horse’s body. Natural Vitamin E is considered roughly 2–3 times more bioavailable than the synthetic form (dl-alpha-tocopherol), meaning your horse absorbs and utilizes more of each unit fed.
Synthetic Vitamin E is made from petroleum derivatives and contains a mixture of isomers, many of which are not well utilized by the body. In contrast, natural Vitamin E provides a single, active isomer that is preferentially absorbed and incorporated into tissues. This makes natural Vitamin E the preferred choice for ensuring optimal antioxidant protection, muscle health, and immune support in horses.
Our Natural Vitamin E is derived from vegetable oils. During purification, only pure d-alpha-tocopherol remains, so no residual proteins are present in the final product.
Vitamin E is fat-soluble, but additional oil is not required for absorption. Horses naturally consume small amounts of fat in forage and concentrates, which is sufficient for uptake. For horses with absorption issues or chronically low blood Vitamin E, feeding with an oil such as Mad Barn’s W-3 Oil may help improve uptake, but it is not necessary in most cases.
The typical feeding rate is 1,000–5,000 IU per day, depending on the horse’s diet, workload, and health status. Horses with neurological disease or confirmed deficiency may require higher levels under veterinary supervision. One scoop of Mad Barn’s Natural Vitamin E provides 1000 IU. For accuracy, use a scale to measure the exact dose your horse requires.
The NRC (2007) lists the tolerable upper intake level for Vitamin E at 10,000 IU/day for a 500 kg (1100 lb) horse, though some studies have safely used higher amounts. While Vitamin E is generally safe above minimum requirements, supplementation beyond the upper limit should be done with veterinary guidance to ensure overall balance in the diet.
Yes. Natural Vitamin E is considered safe to use with most common equine medications, including Prascend, NSAIDs, and ulcer treatments. Consult your veterinarian if your horse is on prescription medications.
Yes. Vitamin E can be safely fed alongside Mad Barn’s Omneity, AminoTrace+, or other supplements. Omneity and AminoTrace+ already supply Vitamin E at levels sufficient for most horses, but additional supplementation may be needed for horses with higher demands, such as those in heavy training or with confirmed deficiency. A diet evaluation is the best way to know if extra Vitamin E is required.
Yes. Vitamin E can be top-dressed on feed and mixed with other supplements. It can be fed wet or dry. If adding to soaked hay cubes or beet pulp, mix it in just before feeding to preserve potency.
Mad Barn’s Natural Vitamin E has a concentration of 600,000 IU per kg. One scoop provides appproximately 1,000 IU of vitamin E. For accuracy, always use a scale when measuring.
The time frame to see results depends on the horse’s baseline Vitamin E levels and health condition. In many cases, improvements in muscle soreness, topline, energy levels, and immune function may be observed within 4–8 weeks of consistent supplementation. Horses with documented deficiencies or neurological conditions may require several months of supplementation before changes are noticeable. Regular blood testing can help to monitor Vitamin E levels and assess the effectiveness of supplementation.
Mad Barn’s Natural Vitamin E supplement provides d-alpha-tocopherol in a concentrated powdered form, making it ideal for situations where additional Vitamin E alone is required. Natural E/Organic Se combines natural Vitamin E with organic selenium in a pelleted format. Selenium is another key antioxidant that works synergistically with Vitamin E to support immune health, muscle integrity, and metabolic balance. Choosing between the two depends on whether your horse’s diet already supplies adequate selenium; if not, Natural E & Organic Selenium may be the more complete option. For help deciding which product is best for your horse, submit their diet for a free diet evaluation.
Mad Barn’s Natural Vitamin E is a highly concentrated, pure source of d-alpha-tocopherol, a bioavailable form of Vitamin E for horses. Our formula contains no fillers or additives and is standardized at 600,000 IU/kg, providing more Vitamin E per gram than many other products. Other supplements often use synthetic forms or lower concentrations, making Mad Barn’s Natural Vitamin E a more effective and cost-efficient choice.
Natural Vitamin E has a guaranteed shelf life of two years from the date of manufacture. Store sealed in a cool, dry, temperature-controlled environment. For long-term storage, keep it in the original packaging or an opaque container. Exposure to light and air can degrade Vitamin E, so clear containers are not recommended for more than 2–4 weeks.
Yes. Vitamin E supplementation is safe for horses with insulin resistance (IR), PPID, EMS, or laminitis. It contains no sugar or starch and does not affect blood glucose or insulin response.
Yes. Mad Barn’s Natural Vitamin E is competition-legal and contains no prohibited substances. Always confirm with your sport’s governing organization, as regulations may change.
Most horses readily consume Vitamin E when top-dressed on feed. For picky eaters, introduce it gradually or mix with soaked pellets, beet pulp, or mash. Mad Barn also offers a 100% Customer Happiness Guarantee to ensure your horse is satisfied with our products.

Why Horses Need Vitamin E
Low vitamin E is common. Don't wait for signs.
Vitamin E is an essential fat-soluble antioxidant that horses must obtain from the diet. In the body, vitamin E is incorporated into cell membranes, where it helps protect fatty acids and other cellular structures from oxidative damage.
During exercise or stress, horses produce more free radicals and require adequate vitamin E to maintain normal antioxidant defenses. This is especially important in tissues with high metabolic activity, including skeletal muscle, nerves, immune cells, and reproductive tissues.
Mad Barn's Natural Vitamin E provides a cost-effective way to add a precise dose of highly bioavailable d-alpha-tocopherol to your horse's diet, without unnecessary fillers or extra bulk.

Which Horses are Most Likely to Benefit from Vitamin E?
Any horse can fall short on vitamin E when fresh pasture is limited. This includes horses eating mostly hay or fortified grain, horses kept on dry lots, horses with restricted turnout, and horses on controlled grazing programs.
Needs can also increase when the body is under more oxidative stress, such as during training, illness, recovery, aging, breeding, growth, or when higher-fat rations are fed. Natural Vitamin E provides a simple way to support vitamin E status when intake, demand, or both are working against the horse.
Limited pasture intake
Horses on hay, dry lots, winter turnout, drought-stressed pasture, restricted grazing, or grain-based diets without fresh grass may not get enough vitamin E from feed alone.
Performance horses
Exercise increases oxygen use and free radical production. Vitamin E supports normal antioxidant defenses, muscle cell membrane integrity, stamina, and post-exercise recovery.
Metabolic horses
Metabolic horses are often managed with restricted pasture access and calorie-controlled diets. Vitamin E helps support antioxidant status without adding sugar, starch, or calories.
Senior horses
Senior horses may benefit from targeted vitamin E support for muscle maintenance, immune function, nerve health, skin and coat quality, and overall antioxidant status.
Neuromuscular support
Low alpha-tocopherol status is associated with several neuromuscular disorders. Horses with diagnosed deficiency or neuromuscular concerns should be supplemented under veterinary guidance.
High-fat diets
Oil and fat supplements add useful calories, but polyunsaturated fats increase antioxidant needs. Vitamin E helps protect lipid-rich cell membranes from oxidative damage.
Stress & recovery
Travel, stress, competition, training, and recovery periods can increase oxidative stress. Vitamin E helps maintain antioxidant defenses when the body is under greater demand.
Breeding & growth
Broodmares, foals, and growing horses have important developmental and reproductive needs. Work with your veterinarian or nutritionist to ensure vitamin E and selenium status are adequate.
Immune support
Vitamin E helps protect immune cell membranes from oxidative damage, supporting the cells involved in normal defense, inflammatory response, and tissue repair.
Vitamin E Requirements
How Much Vitamin E Does Your Horse Need?
The National Research Council (NRC) establishes minimum vitamin E requirements for horses based on body weight and workload. These values estimate the amount of vitamin E needed to prevent deficiency. Exercise increases requirements by raising oxygen use, muscle activity, and oxidative demand.
The following requirements are based on mature adult horses. For help formulating a diet for a growing horse, a breeding or lactating mare, or a horse with documented low vitamin E status, submit your horse's information for a free nutrition consultation.
Horses with documented deficiency, neuromuscular concerns, neurological signs, chronic illness, or poor exercise tolerance may require higher levels of vitamin E. Feeding rates should be determined in consultation with your veterinarian and monitored with bloodwork when low vitamin E status is suspected.

Adequacy target: NRC requirements estimate the minimum vitamin E intake needed to maintain normal status and prevent deficiency signs under typical feeding conditions. These values are based on average nutrient availability, and NRC notes that individual horses may require adjustments based on diet, physiological state, and management conditions. Because vitamin E is required for antioxidant defense, neuromuscular health, immune function, and reproductive support, Mad Barn nutritionists use an adequacy target of 200% of the NRC minimum requirement when additional daily vitamin E support is desired.
How It Works
Vitamin E protects cell membranes from oxidative damage.
Vitamin E works inside the lipid layer of cell membranes, where polyunsaturated fatty acids are most exposed to oxidative damage. Its main role is to act as a chain-breaking antioxidant, stopping lipid peroxidation before it spreads through the membrane.
This is important because cell membranes control what enters and leaves the cell, help maintain electrical gradients, and support normal communication between tissues. When membranes are protected, cells are better able to maintain structure, signaling, and function under normal metabolic stress.
1
Incorporated in cell membranes
As a fat-soluble nutrient, vitamin E localizes within lipid-rich membranes that are susceptible to oxidative damage.
2
Neutralizes free radicals
Vitamin E donates an electron to lipid radicals, stopping the chain reaction of lipid peroxidation before it spreads.
3
Preserves cell function
By protecting membrane lipids, vitamin E helps cells maintain normal structure, transport, signaling, and metabolic activity.
4
Supports antioxidant systems
Vitamin E works with selenium-dependent enzymes and other antioxidant systems that help neutralize reactive oxygen species.
Cellular health affects overall function. Metabolism, exercise, aging, illness, and stress all produce free radicals. Vitamin E helps limit membrane damage at the cellular level before it affects the tissues responsible for strength, movement, immunity, and recovery.

Signs of Low Vitamin E
How Low Vitamin E Can Show Up in Horses
Vitamin E is the horse's primary lipid-soluble antioxidant. It is concentrated in cell membranes, where it helps interrupt lipid peroxidation and protect polyunsaturated fatty acids and membrane structures from oxidative damage.
When vitamin E status is low, tissues with high oxygen use and high metabolic activity are most vulnerable, especially skeletal muscle, nerves, immune cells, red blood cells, and reproductive tissues. Signs can be subtle at first and may appear as poor recovery, muscle soreness, weakness, loss of topline, dull coat, reduced performance, or changes in coordination.
1
Poor recovery after work
Working muscles produce reactive oxygen species. When vitamin E is undersupplied, horses may be slower to recover after exercise or show reduced stamina, muscle comfort, or performance.
2
Muscle soreness or weakness
Vitamin E helps protect muscle cell membranes from oxidative injury. Low status may contribute to muscle soreness, stiffness, weakness, trembling, or difficulty maintaining normal muscle function.
3
Topline or muscle loss
Chronic vitamin E deficiency is associated with neuromuscular disorders that can involve muscle atrophy, weakness, and loss of condition. Bloodwork helps assess whether vitamin E status is part of the problem.
4
Neurological changes
Nervous tissue is highly sensitive to oxidative damage. Low vitamin E status can be associated with neuromuscular signs such as weakness, poor coordination, abnormal gait, or difficulty with normal nerve-muscle communication.
Low vitamin E is evaluated with bloodwork. Signs of deficiency overlap with pain, training issues, illness, selenium deficiency, muscle disorders, and neurological disease. If your horse has sudden, persistent, or unexplained changes in performance, movement, recovery, or coordination, consult your veterinarian and consider testing serum alpha-tocopherol status.
Not all forms of vitamin E deliver the same results for your horse.
Vitamin E can appear on feed and supplement labels as either natural or synthetic, but these forms do not provide the same support for your horse. The difference is stereochemistry, the three-dimensional shape of the molecule, which affects how the body uses vitamin E after absorption.
Natural vitamin E provides d-alpha-tocopherol, a stable natural vitamin E ester. During digestion, it is converted to d-alpha-tocopherol, also known as RRR-alpha-tocopherol, the natural form found in fresh green forage.
In contrast, synthetic vitamin E provides dl-alpha-tocopherol or dl-alpha-tocopheryl acetate. These are all-racemic forms, meaning they contain a mixture of eight stereoisomers. Only one of those eight matches the natural RRR form that the horse preferentially retains in blood and tissues.
Natural Vitamin E
Natural alpha-tocopherol stereoisomer
This form supplies the single natural RRR stereoisomer of alpha-tocopherol. It matches the form horses obtain from fresh pasture and is preferentially retained in circulation and tissues.
RetentionSelected and retained more efficiently after absorption
Synthetic Vitamin E
A mixture of alpha-tocopherol stereoisomers
Synthetic vitamin E is all-racemic (all-rac) alpha-tocopherol. It contains eight stereoisomers with vitamin E activity, but only one of those eight is the natural RRR form.
StructureEight stereoisomers in one synthetic mixture
RetentionNon-RRR forms are metabolized and cleared more readily
How vitamin E is metabolized by horses
Vitamin E is released and absorbed. Tocopheryl acetate forms are converted to free alpha-tocopherol during digestion. Because vitamin E is fat-soluble, it is absorbed with dietary fat and transported in lipid particles.
The liver processes the different forms. After absorption, alpha-tocopherol reaches the liver, where alpha-tocopherol transfer protein, or alpha-TTP, binds the natural RRR form more readily than synthetic stereoisomers.
RRR-alpha-tocopherol is preferentially retained. The natural RRR form is preferentially released by the liver and distributed to the rest of the body.
Natural d-alpha supports status more effectively. Because it supplies the preferred RRR form directly, natural vitamin E is better suited for raising or maintaining blood and tissue alpha-tocopherol levels.
If your horse needs vitamin E support, the form you choose matters.
Two vitamin E products can provide the same IU per serving, but they may not provide the same antioxidant support. Natural vitamin E supplies the RRR form of alpha-tocopherol, the form horses preferentially absorb, retain, and use in tissues. Synthetic vitamin E contains a mixture of forms, with only one matching RRR. For horses that need supplementation, natural vitamin E is the better choice for maintaining healthy alpha-tocopherol status.
