Problem:
A while back there was a lot of noise about resveratrol, a naturally occurring phenol which was touted as a potential anti-aging drug due to its role in regulating the SIRT 1 gene. A number of studies suggested that it could extend the lifespans of model organisms such as D. melanogaster and C. elegans.
Has there been any follow up on this? Have there been any human trials? Please answer the question.
