This is a open-label dose finding study to detect an effective single oral supplement or combination of oral supplements for enhancing whole blood levels of NAD+. Each subject will receive a specific dose of the formulation once daily for 3 days followed by a washout period. Upon completion of the treatment phase, there is a post-treatment period of assessments.~Participants receive assessments of blood tests, vital signs, body weight with completion of questionnaires.~The primary objective of the study is to identify the ideal dosage of an oral supplement to increase whole blood NAD+ levels in adults.~The secondary objective of the study is to monitor for safety from a change in fasting blood chemistry panel parameters after three day's dosing compared to cycle baseline.
The purpose of this study is to assess an effective single oral supplement or combination of oral supplements for increasing whole blood NAD+ levels.
