Deep dives

Resveratrol and Brain Health

Resveratrol shows potential for impacting age-related cognitive decline, particularly in the context of aging and menopause. While animal studies suggest positive cognitive effects, human studies present mixed results, casting doubt on its efficacy as a cognitive enhancer for people. For instance, a study found that patients with mild to moderate Alzheimer's who received resveratrol did see some cognitive improvement, but subsequent attempts to replicate this had disappointing results, revealing no significant benefits after high doses were administered. This disparity highlights the challenges in translating animal model successes into effective human treatments, as evidenced by findings that suggest high doses might not yield the desired cognitive benefits.
