A Clinical Trial to Assess the Absorption, Safety, and Efficacy of an Oral Nicotinamide Adenine Dinucleotide (NAD+) Supplement in Healthy Adults

The goal of this clinical trial is to assess the absorption, safety, and efficacy of an NAD+ supplement in healthy adults. The main question it aims to answer is: What is the change in NAD+ levels in whole blood from baseline to day 56 between the NAD+ supplement and placebo? Researchers will compare the NAD+ supplement to placebo to evaluate its absorption, safety, and efficacy. Participants will be asked to: * Complete questionnaires * Provide blood samples * Consume either the NAD+ supplement or a placebo for 55 days * Have their endothelial function evaluated
