Always satisfied with feedmark products. My warmblood has some kind of neurological problem with hind legs (potentially stringhalt and/or shivers) and the vitamin E does seem to make the symptoms less severe

The Vet thinks my horse has a virus and I am using this to help get him better. I believe it's helping.

Nutrition information

Vitamin E is an antioxidant which horses mainly derive from fresh forages and is therefore easily accessible for horses on pasture (Manthe & Youngs, 2013; Fagan et al., 2020). If your horse has limited or no access to fresh forages or you are unsure about the vitamin E levels in your horse’s diet, an additional vitamin E supplement can be added to make sure the daily vitamin E requirements of your horse are met. The natural form of vitamin E has multifunctional purposes in the horse’s body. The main function of vitamin E is to neutralise free radicals in the body and support the immune system (Fagan et al., 2020). In addition, vitamin E supports reproductive processes, cellular functions and muscle health due to the potential to decrease oxidative stress (Carr & Holcombe, 2009; Finno & Valberg, 2012; Fagan et al., 2020). Therefore, it is recommended to increase the daily vitamin E intake by supplementing Natural Vitamin E™ for horses that require liver and muscle support and horses performing heavy work. Due to the multifunctional nature of vitamin E it is also recommended to increase its daily intake to support broodmares and stallions during the breeding season and to support foals health and development (Contri et al., 2011).

The natural form of vitamin E, RRR-alpha-tocopherol acetate, is more bioavailable in comparison to synthetic vitamin E (Fiorellino et al., 2009), increasing its absorption and optimising its supportive function (Gagné et al., 2009). Natural Vitamin E™ is suitable for all horses but a higher dosage is especially recommended for horses that need liver and muscle support, horses performing heavy work and for all breeding stock (Finno & Valberg, 2012; Secombe & Lester, 2012).

Natural Vitamin E™ can be fed in combination with all other supplements from the Feedmark range to increase and optimise levels of vitamin E in the diet.
