Vitamine E voor je paard: waarom geven en wanneer het belangrijk is

Key takeaways from this blog: vitamin E for your horse

Vitamin E is crucial for the health and performance of horses. It acts as an antioxidant, supporting muscles, the immune system, the nervous system, and fertility. Horses that train intensively, eat little fresh grass, young horses, or broodmares often need additional vitamin E. Deficiencies can lead to muscle problems, reduced performance, increased susceptibility to disease, and even neurological disorders.

Key Benefits of Vitamin E for Horses:

Supports muscle function and recovery
Strengthens the immune system
Protects the nervous system
Promotes fertility and protection of the foal

Regular, consistent supplementation (for example annually during winter) helps prevent deficiencies and is suitable for horses of all ages and training levels.

Vitamin E for horses

A healthy horse starts with proper nutrition, but in many cases, basic feed alone isn’t enough.

Vitamin E plays a vital role in your horse’s health and performance. It’s a powerful antioxidant that protects cells, supports muscles, strengthens the immune system, supports the nervous system, and promotes fertility.

Training, recovery, limited grazing, or increased muscle strain can all raise your horse’s vitamin requirements. A vitamin E course can make a world of difference: for health, muscles, and overall performance.

Key Functions of Vitamin E for Your Horse

Vitamins support, among other things:

Healthy muscle function and recovery after training
Waste disposal
Overall health by compensating for possible deficiencies in the daily ration

Vitamins are not a luxury, but a smart investment in your horse's health!

Which horses need extra vitamin E?

Sport horses and horses in intensive training
Horses with limited access to fresh grass (the natural source of vitamin E)
Broodmares
Young horses

Symptoms of Vitamin E Deficiency

Muscle soreness, stiffness and trembling after exercise
Reduced performance and general weakness
Increased susceptibility to illness

5 reasons to supplement your horse with vitamin E

1. Optimal muscle function of your horse

Vitamin E protects your horse's muscles during exercise.

During exercise, small reactive particles called free radicals are formed in the muscles. These can cause damage and contribute to muscle fatigue and stiffness. Vitamin E acts like a protective shield, neutralizing these particles so muscles recover faster and are less prone to acid buildup. This helps active horses perform better and stay energetic for longer.

Global Medics Vit. E Liquid is ideal for horses that benefit from fast and easy absorption, supporting healthy muscle and nerve function.

2. Limited access to fresh grass

Fresh grass is the main natural source of vitamin E. Horses that spend a lot of time in the stable have a higher risk of deficiency and may need extra vitamin E to stay healthy. Without sufficient fresh grass, shortages can develop more quickly.

Horses that mainly eat hay often require additional vitamin E. Supplementation helps prevent deficiencies and supports overall health and vitality.

TRM's Vita-E-Plus is a complete formula that supports muscle recovery after exercise, with easy dosing and a combination of essential vitamins and minerals.

3. Strengthening your horse's immune system

Vitamin E supports your horse’s natural defenses and contributes to antibody production, helping reduce susceptibility to illness and infection.

Basic 1 Pure Vitamin E is a liquid, concentrated source of vitamin E that supports optimal muscle function, nerve health, and overall vitality.

4. Supporting your horse's nervous system

Vitamin E is essential for healthy nerve signal transmission. A deficiency can lead to neurological issues such as muscle stiffness and coordination problems. In severe cases, long-term deficiency may result in Equine Motor Neuron Disease (EMND), a condition that mainly affects horses kept in stables and impacts motor function.

By supplementing vitamin E in time, you help protect the nervous system and maintain your horse’s mobility and vitality.

Orthosal Vitamin E Horse from Navalis is suitable as a targeted vitamin E supplement and supports muscle function with daily use.

5. Improved fertility and foal protection

Vitamin E is important for mare fertility and supports a healthy pregnancy. It helps transfer antibodies to foals through colostrum, giving your foal the very best start. It also contributes to the overall health of the mare during pregnancy and lactation. Regular supplementation can help prevent health issues in both mare and foal.

Reverdy 's E Naturelle is a high-quality concentrate of protected natural vitamin E, made with natural ingredients and excellent bioavailability for optimal muscle function.

💡 Tip: Make it part of your routine

Horses are just like us: they like routine. Giving vitamins consistently and in a structured way helps your horse get the maximum benefit.

An annual vitamin E course during winter can provide extra support when access to fresh grass is limited. This helps replenish the body before deficiencies develop, contributing to stronger immunity and healthier muscles. It’s especially important for horses that spend most of their time in the stable or train intensively. By supplementing vitamin E in time, you help your horse stay strong and energetic throughout winter.
