What about weight and blood sugar?
A 2024 meta-analysis combined six studies using roughly 51–450 mg daily. It found no significant pooled benefit for body weight, body fat, blood pressure, fasting glucose, insulin or the measured blood fats. Promising laboratory mechanisms have not translated into a reliable benefit on these human measures. 1
Why researchers still study it
The Alzheimer’s Drug Discovery Foundation describes animal findings involving inflammation, oxidative stress and cognition in impaired models. These are reasons to investigate the compound, not evidence that supplements improve human memory or prevent dementia. 2
