Nicotinamide Mononucleotide Supplementation for Exercise Tolerance Improvement in Healthy Older Adults

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Aging, Frailty, Exercise Tolerance, Healthy Male and Female Subjects

In brief

This is a randomized, double-blind, placebo-controlled, two-arm crossover clinical trial evaluating the effects of a patented age-reversal therapy, EGA®, compared to conventional nicotinamide mononucleotide (NMN) supplementation. The study will assess safety and efficacy in improving exercise tolerance and modulating biomarkers of aging in healthy older adults. The primary outcome is cycle ergometry constant work rate (CWR) exercise tolerance, measured as time to fatigue. Secondary outcomes include changes in peak oxygen consumption (VO₂peak), critical power, anaerobic work capacity, lactate threshold, and NAD⁺ metabolite levels. EGA® is composed of three metabolomic compounds that are endogenous to humans. The formulation has been used in prior exploratory studies and real-world applications, which have helped inform the design of this current trial.

Significant neurological impairments that hinder comprehension of instructions or participation in exercise
Terminal illness or conditions limiting life expectancy or ability to complete the study
Severe cognitive impairment preventing informed consent, protocol adherence, or comprehension of interventions
Significant orthopedic limitations or injuries that prevent safe exercise participation
Use of NMN, NR, or other NAD+-altering supplements within the past 14 weeks
