Sirtuins and their Biological Relevance in Aging and Age-Related Diseases

This article reviewed research on sirtuins, proteins that help control how cells use energy and respond to stress. It discussed findings from cells, animals, and some human studies. The evidence suggested that sirtuins may affect aging, but results varied and the effects were not fully understood. This was a review, not a new experiment, so it did not test one treatment in a specific group of people.

What this means for you: You should not buy a sirtuin-boosting supplement based on this article alone. The findings are interesting, but they do not show that these products slow aging or prevent disease in people.
