Life Extension Nad+ Cell Regenerator and Resveratrol Elite, GF, 30 Veg Caps Boost longevity and cellular energy with Optimized NAD+ Cell Regenerator(TM) and Resveratrol Elite(TM) from Life Extension(R). It features NIAGEN(R) (nicotinamide riboside), which increases cellular levels of NAD+, an enzyme critical to healthy cellular energy production. A 2017 study found that older adults taking a daily dose of 250 mg of nicotinamide riboside had a 40% increase in NAD+ levels after just 30 days. Additional studies have shown that increasing NAD+ also supports healthy metabolic and cognitive function. The formula includes resveratrol, a plant compound, which supports the healthy expression of genes associated with slowing down aspects of the aging process. It promotes healthy blood sugar levels already within the normal range and supports enhanced mitochondrial function. The NAD+ Cell Regenerator and Resveratrol Elite formula also includes a blend of red grape and wild blueberry for additional polyphenols, anthocyanins and more, along with fisetin and quercetin, phytonutrient compounds that augment resveratrol's healthy effects, promote cardiovascular health, support healthy cellular function, reduce oxidative stress and more. Promote healthy cellular metabolism, gene health and more with NAD+ Cell Regenerator and Resveratrol Elite. 1) Dellinger, R.W., Santos, S.R., Morris, M. et al. npj Aging Mech Dis 3 , 17 (2017).
