Equine Performance & Recovery Support

Protecting a Horse’s Health with a Reservatrol Analogue, Antioxidants and Curcumin

Many disorders in both humans and animals have been directly linked to inflammation and oxidative stress. Indeed, it is impossible to separate the two due to their intricately linked reactions. Certain events that initiate inflammatory and oxidative stress responses can be avoided; however, for most of us, and particularly for the horse, there is the certainty that one will always be confronted with these stressors to some degree. Due to the ubiquitous nature of inflammatory and oxidative stressors, it is imperative to prevent exacerbation or prolongation of the body’s responses, as they can ultimately result in poor performance, metabolic disturbances and decreased quality of life. Various dietary strategies have been designed to combat inflammatory and oxidative insults. For example, anti-inflammatory diets, such as one that is relatively high in omega-3 fatty acids and low in omega-6 fatty acids, are often advocated for healthy living. However, other nutrients can play a significant role in controlling inflammation and oxidative stress.


Pterostilbene is a compound that is chemically very similar to resveratrol, which received much public and scientific attention in past years for its purported ability to increase lifespan as well as protect against various diseases and conditions.1 Unfortunately, resveratrol has limited potential due to its poor bioavailability and/or very quick degradation once it is absorbed. However, as a methylated analogue of resveratrol, pterostilbene is far more promising. For example, oral intake studies indicate that pterostilbene is 70 to 90 percent bioavailable whereas resveratrol has a 20 to 30 percent absorption rate.2,3 Furthermore, pterostilbene remains intact in the blood for up to 7 times longer than resveratrol.4 Biological activities attributed to pterostilbene range from analgesic, anti-inflammatory, antioxidant, antiaging, vascular health supporting and neuroprotective effects.3,5-9 The mechanisms of action attributed to pterostilbene include both modulation of gene expression and enzymatic activity.10


Superoxide Dismutase (SOD) is a metalloenzyme that is present in nearly all cells where it catalyzes the dismutation of superoxide to oxygen and hydrogen peroxide. Although the importance of SOD in modulating oxidative stress has been well understood for years, few trials have reported on the benefits of oral supplementation with this enzyme until relatively recently. To date, improvements in self-perceived fatigue,11 increased activities of circulating antioxidant enzymes and red blood cell resistance to hemolysis,12 and reductions in intestinal tract stress proteins13 have been reported in humans and animals. In the horse, oral supplementation for 60 days with a melon extract high in SOD during intense training was associated with maintenance of resting plasma levels of creatine kinase,14 an enzyme that is often increased after muscle damage associated with exercise. Furthermore, plasma resistance to hemolysis improved in the supplemented group and was significantly greater than that in the control group.

Other antioxidants, such as vitamins E and C, have also been utilized to aid in the protection against oxidative stress and inflammation. Vitamin E has been negatively correlated with levels of certain markers of lipid peroxidation in exercising horses,15 and vitamin C supplementation has been shown to reduce markers of lipid peroxidation and maintain plasma antioxidant capacity in thoroughbred race horses.16 The combination of vitamins E and C have been utilized to support horses with recurrent airway obstruction.17


The benefits of curcumin, which is the primary active ingredient of turmeric, have had a prominent role in Indian Ayurvedic medicine since 1900 BC.18 Curcumin purportedly has anti-inflammatory, hepato-protective and antioxidant properties19 and is a suggested therapeutic agent for inflammatory conditions 21 as well as cognitive disorders.20 Curcumin’s biochemical benefits are due, in part, to regulation of transcription factors such as PPARgamma and NF-kappa beta.20,21 The resultant improvements in cytokine and inflammatory markers is demonstrated by reductions in TNF-alpha, IL-1beta, IL-6 and the COX-2 and LOX enzymes.19 Franck et al.22 studied curcumin’s effect on inflammation in horses by stimulating equine neutrophils and then measuring production of oxidative products. 23-25 These investigators reported a dose-dependent inhibition of curcumin on reactive oxygen species production and myeloperoxidase activity. Another in vitro study showed that curcumin protects equine cartilage explants against IL-1beta induced degradation.26

Pterostilbene vs. Resveratrol

  • Pterostilbene is a methylated analogue of resveratrol so chemically very similar
  • Pterostilbene is 3 times more bioavailable than resveratrol
  • Pterostilbene remains intact in the blood 7 times longer than resveratrol
