What are the effects of tocotrienol and tocopherol supplementation on brain health?

Label:chem

Topic
Vitamin E, which includes tocotrienol and tocopherol, has been extensively studied for its neuroprotective properties. Tocopherols, especially α- and γ-forms, are associated with improved cognitive performance, reduced neuroinflammation, and preservation of synaptic proteins. Tocotrienol, despite its lower plasma bioavailability, has been shown to have structural protection effects, particularly in white matter. Both compounds exhibit complementary effects, suggesting a potential advantage of combined supplementation.

From: "Shifting Perspectives on the Role of Tocotrienol vs. Tocopherol in Brain Health: A Scoping Review", Int. J. Mol. Sci. 2025, 26(13), 6339;
Answer
Tocotrienol and tocopherol supplementation have been shown to improve cognitive performance, reduce neuroinflammation, and protect brain structure. Tocopherols, particularly α-tocopherol, are associated with better cognitive outcomes and reduced oxidative stress. Tocotrienols, while less studied, show promise in protecting white matter and reducing neurodegenerative markers. Combined supplementation may offer synergistic benefits for brain health.
