NAD Boosters for Energy and Memory? ConsumerLab Reviews NAD+, NAHD and NMN Supplements

White Plains, New York, November 5, 2021 — Most cells in the body use NAD (nicotinamide adenine dinucleotide) in the process of energy production, and compounds that boost blood levels of NAD are often sold in supplements marketed for a wide range of benefits, from increasing energy and improving cognitive function, to lowering cholesterol and controlling blood sugar. But do supplements containing these compounds really work, and which provide the best quality and value? To find out, ConsumerLab carefully reviewed the evidence and purchased and tested popular NAD boosters containing NAD, NADH (nicotinamide adenine dinucleotide hydride), nicotinamide riboside (including Niagen), and NMN (nicotinamide mononucleotide), carefully checking them to see if they contained their claimed amounts of key ingredients. The products were also tested for contamination with lead, cadmium, and arsenic, and all regular tablets were also tested to determine if they would properly disintegrate.
