This randomized controlled trial evaluated the immunomodulatory effects of palm-derived tocotrienol-rich fraction (TRF) on the immune response to influenza vaccination in 150 healthy adults. Daily TRF supplementation significantly enhanced anti-influenza antibody production across all doses, with the highest titers observed in the 400 mg group. Notably, lower doses also effectively supported humoral immunity.
Key findings
- TRF supplementation significantly augmented anti-influenza antibody production across all doses.
- The 400 mg TRF group exhibited the highest antibody titers.
- A selective Th1-type immune response was observed in all TRF-supplemented groups.
- Lower doses of TRF may provide a cost-effective strategy for enhancing humoral immunity.
Why it matters
Understanding the immunomodulatory effects of TRF could inform strategies to enhance vaccine responses, particularly in populations where immune function may be compromised. This research highlights the potential for lower doses to effectively support immunity.
