RiaGev™ is the first and only commercially available ingredient that uniquely and patentedly combines BioenergyRibose® with a form of vitamin B3. It is formulated to efficiently and quickly increase NAD (nicotinamide adenine dinucleotide) in the body. NAD is a coenzyme and plays a key role in energy production in the body. Research indicates that NAD levels in our bodies drop by 50% between the ages of 40 and 60, which negatively impacts our cells and healthy aging.
