<p>ResveraCel combines nicotinamide riboside with resveratrol and cofactors to support healthy aging.* Nicotinamide riboside is the most potent direct precursor to nicotinamide adenine dinucleotide (NAD+) and reinforces the multiple functions of cellular mitochondria.* Resveratrol mirrors the effect of calorie restriction by activating the sirtuin group of proteins. Quercetin phytosome also enhances sirtuin action – research shows it slows the breakdown of resveratrol in the body. Betaine provides premier support for methylation
