Resveratol may help boost endurance, prevent weight gain, and improve energy.Resveratrol stimulates enzymes called sirtuins, which control important functions throughout the body, including DNA repair, cell life, aging, and fat production. Resveratrol inhibits production of mature fat cells and hinders fat storage at the cellular level. Resveratrol decreased adipogenesis and viability in maturing preadipocytes; these effects were mediated not only through down-regulating adipocyte specific transcription factors and enzymes but also by genes that modulate mitochondrial function. Additionally, resveratrol increased lipolysis and reduced lipogenesis in mature adipocytes. Several new resveratrol studies add to several previous studies supporting the role of resveratrol to help improve blood sugar metabolism. Resveratrol decreased blood sugar and triglycerides while boosting levels of the all important blood sugar regulating hormone adiponectin. Resveratrol boosted cellular levels of AMP-activated protein kinase (AMPK), an important cellular signal involved with the biological clock and use of energy within a cell. In other words, when you feel fatigued or jet-lagged your AMPK is on the blink. The net result of boosting AMPK was to significantly improve the liver’s ability to metabolize sugar that resulted in lower blood levels of hemoglobin A1c (a key marker of improved glucose metabolism).
