Small molecule activators of sirtuins extend Saccharomyces cerevisiae lifespan

Researchers tested resveratrol and other small chemicals on purified sirtuins, proteins involved in cell aging. They also gave the chemicals to yeast cells, a type of fungus used in laboratory aging studies. The treated yeast cells produced new cells for up to 70% longer than untreated cells. This effect depended on Sir2, a yeast sirtuin protein.

What this means for you: This was a yeast study, not a human study, so it does not show that resveratrol supplements or similar products extend human life. You can ignore this as a reason to buy a supplement.
