Scientists have long recognized that calorie restriction counters the physiological signs of aging. Extensive research shows that reducing intake by about a third delivers profound health benefits and, in some cases, extends lifespan.
From a public health standpoint, this strategy is often impractical or risky for many. However, a recent study reveals that daily doses of nicotinamide riboside (NR), a natural dietary supplement, replicate calorie restriction (CR) effects by activating the same key molecular pathways driving its benefits. NR also improved blood pressure and arterial health, particularly in those with mild hypertension.
