Tocotrienols, a family of vitamin E compounds, exhibit neuroprotective effects, according to two recent scientific reviews, thereby supporting brain and cognitive health as well as healthy aging.

In the first review, published in the International Journal of Molecular Sciences, researchers analyzed 24 articles of experimental studies to evaluate the neuroprotective effects of tocotrienols on the brain. The findings covered multiple neuroprotective mechanisms, including:

  • Antioxidant and anti-inflammatory effects, reducing oxidative stress, lipid peroxidation, and inflammatory markers.
  • Regulation of gene and protein expression, modulating key molecular pathways linked to stroke-induced injuries, brain health, and resilience.
  • Enhancement of memory and cognitive function, supporting learning, memory, and behavioral performance in aging and neurodegeneration models.
  • Preservation of cell and organelle morphology, protecting neuronal structure and maintaining mitochondrial integrity.

A second review, also published in the International Journal of Molecular Sciences, compared the distinct roles of tocotrienols and tocopherols in brain health. The authors found that while alpha-tocopherol is the most widely studied, tocotrienols exhibited more potent inflammatory-modulating and antioxidant capacity, and may preserve white matter integrity and modulate neurodegenerative pathways. Together, both forms of vitamin E may provide complementary benefits for cognitive health, neuroinflammation, and structural brain protection, the authors concluded.

“Backed by growing scientific evidence, tocotrienols are emerging as promising neuroprotective agents that support and protect brain cells, cognitive functions, and memory as well as healthier aging,” said Ariati Aris, PhD, scientific affairs specialist at PhytoGaia, an ingredient supplier specializing in palm-derived tocotrienols. “A recent published clinical study shows that TocoGaia enhances psychological well-being, modulates oxidative stress, and supports genomic stability in aging populations. Building on this, we are now planning a new randomized-controlled trial with TocoGaia for cognitive health, which we believe will further validate tocotrienols’ role as next-generation brain phytonutrients.”

“For our partners and brand owners, TocoGaia offers a unique opportunity to differentiate their formulations with a next-generation vitamin E that delivers more than conventional tocopherols. With the latest science reinforcing tocotrienols’ potent neuroprotective potential, TocoGaia is the perfect ingredient for companies looking to innovate and create value in areas such as in brain and cognitive health, healthy aging, and functional nutrition.”
