Nicotinamide Riboside Sustain by Jarrow Formulas
Each of Jarrow Formulas’ Sustain tablets provide 150mg of total Niagen, a branded form of Nicotinamide Riboside, a precursor to nicotinamide adenine dinucleotide (NAD+). The ingredient has been shown to boost NAD+ levels, a key component of energy production. NAD+, a metabolite of vitamin B3 (niacin), is essential to mitochondrial function and enables cells to convert both glucose and fatty acids to energy. Hence, the supplement is marketed for its cognitive function benefits.
