Tocotrienol Confers Neuroprotection & Improves Exercise Endurance

Tocotrienol is a form of vitamin E. There are 2 forms of vitamin E in nature – Tocopherol and Tocotrienol. The only difference between tocopherol and tocotrienol is by the side tails of their molecular structure. Tocopherol possesses saturated side chain, while tocotrienol has 3 double bonds or unsaturated side chain, and thus known as “Unsaturated Form of vitamin E”. The unsaturated side chain of tocotrienol is believed to be the key for tocotrienol to confer unique biological activities that are not associated with tocopherols.

Tocotrienol is a fat-soluble compound and it exhibits poor absorption via oral supplementation. Therefore, the SupraBio™ system, a patented self-emulsifying delivery system is developed for tocotrienols to increase the absorption of individual tocotrienol up to 300%, which marks the second generation of tocotrienol complex. EVNol SupraBio™ has been used in many human clinical studies, for example brain health related studies that are funded by NIH (National Institute of Health) since 2000 on the protection of neuron cells from stroke/ toxic induced injury and degeneration. It begins from mechanisms to in vivo studies, and now the phase I and II of human clinical studies, conducting at the Ohio States University, Wexner Medical Center. Additionally, four large epidemiological studies found that plasma vitamin E tocotrienol is inversely associated with reduced risk of mild cognitive impairment (MCI) and Alzheimer’s disease (AD).

In terms of sports nutrition, whey protein and tocotrienol both increase sports endurance. And when both tocotrienol and whey protein combine, a more potent effect was shown in which the synergistic effects of tocotrienol and whey protein show further enhancement in exercise endurance.

Popular Applications of ExcelVite’s Tocotrienol Ingredient

ExcelVite’s main flagship products are palm tocotrienol (EVNolTM/ EVNol SupraBioTM) and palm mixed-carotene (EVTeneTM) extracted from virgin crude palm oil/ palm fruits. Most of the applications for tocotrienols are dietary supplements in the form of soft gelatin capsule, hard gelatin capsules and tablets. However for the last 10 years, the application has been expanded to cosmetic – both oral and topical application. For recent 2 to 3 years, due to the fact that tocotrienol is a more potent form of vitamin E or antioxidant and GRAS (GRN Notice No 307), the applications for tocotrienol have been extended to functional food and beverages such as sports drinks, functional beverages like Toco-Oat.

ExcelVite’s Actions to Address Main Issue Related to Palm and Sustainability

The main concern among consumers is regarding the sustainability of palm oil, taken up by the green organization. An important factor to consider when one talks about sustainability – the source/ location of the crude palm oil/ palm fruits (where the palm trees are planted and harvested). ExcelVite only purchases sustainable oil palm from Peninsula Malaysia where most of the croplands are more than 25 years, hence all the palm related products from ExcelVite are sustainably produced. In addition, ExcelVite is also a member of RSPO (Roundtable Sustainable Palm Oil.
