Today, scientists around the world are studying resveratrol to determine how it helps fight aging and prolong life span. Current evidence suggests that resveratrol exerts antioxidant effects, boosts energy production, and favorably alters patterns of gene expression.
Oxidative stress is implicated in numerous disease processes and in aging itself. Resveratrol demonstrates powerful antioxidant capabilities, with profound implications for human health. Scientists report that resveratrol inhibits the oxidation of dangerous low-density lipoprotein (LDL) and scavenges harmful hydroxyl radicals. Resveratrol also helps preserve levels of glutathione, one of the body’s most essential antioxidants.6 According to prominent resveratrol investigator Dr. Milos Sovak, “There is no question that resveratrol is one of the best free-radical scavengers and that it has many effects whose ramifications might affect not only longevity but also general health.”
Resveratrol stimulates energy production in the cellular powerhouses known as the mitochondria. Diminished mitochondrial energy production is associated with reduced longevity. By enhancing the production of life-sustaining energy, resveratrol may help protect against metabolic disease and obesity, thereby improving health and prolonging survival in animals.7
Growing evidence indicates that resveratrol influences many genetic pathways, which may underlie its ability to lengthen life. In the recent Harvard study, investigators noted that a high-calorie diet produced numerous changes in gene expression. However, supplemental resveratrol opposed the effects of this high-calorie diet in 144 of 153 significantly altered genetic pathways. Moreover, resveratrol’s effects were dose dependent, with larger amounts yielding greater effects, leading the investigators to suggest that resvera-trol may offer “new approaches for treating obesity-related disorders and diseases of aging.”7
Some of the genetic pathways influenced by resveratrol are similarly affected by caloric restriction. For example, caloric restriction is associated with long-term activation of AMP-activated kinase (AMPK), a metabolic enzyme promoting insulin sensitivity and fatty-acid oxidation. Resveratrol likewise increases AMPK activity, which is associated with life-span extension.5
Scientists believe that caloric restriction increases life span in part through its effects on the sirtuin genes.5 Present in all life forms, sirtuin genes are associated with aging and longevity. Resveratrol may confer benefits similar to those of caloric restriction by influencing the sirtuin gene known as SIRT2.5,8-10 In the Harvard study, resveratrol helped counteract changes in SIRT2 expression induced by a high-calorie diet.5
“The genes and pathways [affected by resveratrol or by caloric restriction] are related to activation of sirtuins, a class of histone deacetylase enzymes (HDACs) involved in cell death and life-span regulation,” Dr. Zhao-Wilson told Life Extension. “Based on the large body of evidence, the resveratrol/sirtuin activators have become the focus of pharmaceutical drug discovery efforts now [targeting] HDACs.”
Researchers believe that compounds like resveratrol that either activate or inhibit sirtuin activity may have therapeutic potential for a broad array of human diseases, including cancer, diabetes, heart failure, and neurodegenerative conditions such as Alzheimer’s and Huntington’s disease.
