I was very intrigued by the potential for NR and NMN to promote cellular health and retard the aging process, and initial results conducted in laboratory animals were promising. However, studies with these compounds in humans has been generally disappointing, as has Sinclair’s continuation to tout these and other compounds, despite the results of many studies. Of course, he has a financial interest in several products. Separating hype from reality requires extensive and expensive research. Hopefully more studies will be done and results will be more favorable. Until then, I’ve stopped sending my money for dubious products and I am relying on a good, balanced diet, vigorous exercise, and a positive mindset.
