Charles Brenner Critiques David Sinclair's Best-Selling Book on Aging

This was a critical review, not a new experiment. The author examined claims about aging, genetics, supplements, and ways to extend life. The review argued that some impressive results came from cells or mice, not people. It also said that human evidence for many proposed treatments remains limited or uncertain. No people were enrolled in this review.

What this means for you: Do not buy supplements or treatments based on popular anti-aging claims alone. Look for results from large, well-designed human studies, because promising laboratory findings may not help people.
