EVNol SupraBio™ supplementation increases tocotrienols in the brain and other vital organs, study shows
- EVNol SupraBio™ mixed tocotrienols significantly increases tocotrienol levels in blood, skin, adipose, brain, cardiac muscle, and liver over time
- Effective dosage is 200 mg/day, twice daily, for at least 12 weeks
- Supplementation may also offer clinical value for liver transplant patients
This study was designed to measure the tissue and organ uptake of supplemental vitamin E given either in the tocopherol (TCP) or tocotrienol (TE) form, the two chemical classes of natural vitamin E.
For this study, researchers studied a total of 80 adults who were given either EVNol SupraBio™ mixed tocotrienols* (200 mg, twice daily) or alpha-tocopherol (200 mg, twice daily). Skin and blood vitamin E levels were determined from healthy participants (n=16) following 12 weeks of oral supplementation. Vital organ vitamin E levels were determined by HPLC in adipose, brain, cardiac muscle, and liver tissue of surgical patients following supplementation (mean duration, 20 wk; range, 1-96 wk). Participant compliance with supplementation was reported to be over 90%.
Results indicate that oral supplementation of TE significantly increased levels of TE in blood, skin, adipose, brain, cardiac muscle, and liver over time. Moreover, alpha-TE was delivered to the brain at a level reported to be neuroprotective in experimental models of stroke.
In prospective liver transplantation patients, oral TE lowered the model for end-stage liver disease (MELD) score in 50% of patients supplemented, while only 20% of TCP-supplemented patients showed a reduction in MELD score.
These findings indicate that EVNol SupraBio™ mixed tocotrienols (200 mg, twice daily) increases the level of tocotrienols in vital organs, including brain, and may offer clinical value for liver transplant patients.
