Description
This randomized, double-blind, placebo-controlled, two-arm crossover trial will compare the effects of two NAD⁺-modulating interventions-EGA® and conventional nicotinamide mononucleotide (NMN) supplementation-on exercise tolerance and metabolic biomarkers in healthy older adults. EGA® is a proprietary formulation composed of three endogenously occurring metabolomic compounds (including NMN) and has been used in prior non-FDA-regulated studies involving human participants. The EGA® arm will involve a twice-daily oral dose of EGA® containing 1000 mg of NMN, while the comparison arm will involve twice-daily oral dose of 1000 mg of conventional NMN per day. Doses will be self-administered each morning and evening with water.
The primary endpoint is time to fatigue during constant work rate cycle ergometry (CWR-Tlim), a validated surrogate for submaximal exercise tolerance. Secondary endpoints include peak oxygen uptake (VO₂peak), lactate threshold, anaerobic work capacity, and critical power, in addition to circulating NAD⁺ and its related metabolites.
The trial is designed to evaluate the short-term physiological effects and biological activity of EGA® compared to conventional NMN under tightly controlled exercise testing and training conditions. Data from this study will be used to inform the therapeutic potential of EGA® in improving physical performance in healthy older adults (60-80 years). Future directions may include further clinical evaluation or regulatory submissions, depending on outcomes from this pilot investigation.
