Supplementation with plant oil extract may improve influenza vaccine efficacy

A clinical trial conducted by researchers at Monash University Malaysia and the Malaysian Palm Oil Board found that daily supplementation with tocotrienol-rich fraction (TRF), a vitamin E extract from plant oils, significantly enhanced antibody responses to the influenza vaccine in healthy adults. Participants who received TRF, especially at the highest dose of 400 mg, showed increased IgG titers compared to placebo after vaccination. The study suggests TRF supplementation could be a cost-effective strategy to improve vaccine efficacy and recommends further research into its long-term effects and potential applications with other vaccine types.
