Safety and Pharmacokinetics of Nicotinamide Mononucleotide (NMN) in Healthy Adults.

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to investigate the safety, pharmacokinetic profile, and effects of nicotinamide mononucleotide (NMN-C) in healthy adults, 18-65 years of age. The effects will be studied over the course of 30 days in a repeated-dose study through the collection of blood and urine samples, and administration of surveys and questionnaires.
