Phase I study to evaluate the safety and efficacy of resveratrol in enhancing the function of natural killer cells - Safety and efficacy of resveratrol in enhancing NK activity

The administration of MES resulted in a significant increase in the antioxidant activity of the plasma and a decrease in the protein carbonyl content of the plasma compared with the corresponding baseline levels. The circulating numbers of B and T lymphocytes remained essentially unchanged throughout the course of the study, however MES consumption was associated with an increase in the proportion of circulating NK cells and regulatory T cells (CD3+, CD4+, CD25, CD127low/neg).
