What roles do caloric restriction, resveratrol, and melatonin play in aging and age-related diseases, particularly concerning sirtuin 1 (SIRT1) activation?
Polyphenol Antioxidant Blend, a review (Mechanisms of Ageing and Development 2015, PMID 25824609) — melatonin, an endogenous free radical scavenger that declines with age, also activates sirtuins and has anti-inflammatory and circadian rhythm regulatory functions. No numeric effect size is reported for Polyphenol Antioxidant Blend in the source abstract.

Caloric restriction, resveratrol, and melatonin may combat aging and age-related diseases by activating sirtuins and scavenging free radicals.
The question
What roles do caloric restriction, resveratrol, and melatonin play in aging and age-related diseases, particularly concerning sirtuin 1 (SIRT1) activation?
What they tested
Free radicals contribute to aging through oxidative damage, but also modulate signaling pathways like those related to sirtuins. Caloric restriction extends lifespan by inducing sirtuins. Resveratrol and melatonin, both sirtuin activators and free radical scavengers, may offer synergistic benefits for health and longevity.
How they did it
This abstract is a review and does not describe specific experimental methods. It synthesizes existing research on caloric restriction, resveratrol, and melatonin.
What they found
Caloric restriction extends lifespan and improves healthspan, partly by inducing sirtuins. Resveratrol, a polyphenol, has antioxidant, antifungal, and sirtuin-activating properties. Melatonin, an endogenous free radical scavenger that declines with age, also activates sirtuins and has anti-inflammatory and circadian rhythm regulatory functions. Both melatonin and resveratrol are present in foods and may have synergistic effects.
What it means
Caloric restriction, resveratrol, and melatonin are implicated in modulating aging processes, partly through their effects on sirtuins, particularly SIRT1. Their presence in diet and potential synergistic actions suggest they could promote health and longevity.
Limitations
This abstract does not present new experimental data or discuss specific limitations of the reviewed studies. It is a conceptual overview.

Nicotinamide Mononucleotide (NMN)
In randomized controlled trials, NMN reliably increases blood NAD+ levels and has generally been well tolerated at oral doses up to roughly 900-1250 mg/day, with some trials reporting modest improvements in skeletal-muscle insulin sensitivity, walking speed, aerobic capacity, sleep quality, and diastolic blood…
Polyphenol Antioxidant Blend
Observational cohorts consistently link higher dietary and urinary polyphenol (and flavonoid) intake to lower all-cause and cardiovascular mortality—a meta-analysis of 16 cohorts (462,194 adults) found roughly 13–15% lower mortality with higher flavonoid intake—and a 2025 UK Biobank analysis tied greater flavonoid…
