Resveratrol improves insulin sensitivity in older adults with impaired glucose tolerance, supporting its potential as an intervention to delay aging based on its effects on the insulin/IGF-1 pathway.
Resveratrol may improve insulin sensitivity in older adults with impaired glucose tolerance. While more research is needed, it represents a potential dietary supplement to support metabolic health. Consult a healthcare provider before starting.
LimitedSupportsLOW confidence
A recent pilot study conducted in 10 older adults suggests that resveratrol improved insulin sensitivity in individuals with impaired glucose tolerance (94). These data combined with animal studies provide support for larger studies of the benefits of resveratrol in humans (95).
Why this rating
Pilot study with small sample size (n=10), though supported by animal studies.

- The ApoE E4 isoform is deleterious to longevity, while the E2 isoform is protective, with the E4 allele conferring up to an 8-15 fold increased risk for Alzheimer's disease and premature death from age-related conditions.Good
- FOXO3a variants are associated with increased human life span, with the minor allele conferring a higher odds of longevity (OR 2.75) in centenarians of Japanese descent, and this association has been replicated in diverse populations including German, Italian, Chinese, and Danish cohorts.Good
- Lower levels of IGF-1 are associated with longer life span in mice, and this region overlaps with human longevity quantitative trait loci, suggesting a conserved mechanism where IGF-1 regulation influences longevity.Moderate
