Brief summary
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.
Detailed 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Time to Fatigue During Constant Work Rate Cycle Ergometry (tLIM). | Measured at the beginning and end of each 4-week intervention period. | Duration (in seconds) that participants can sustain a constant submaximal workload on a cycle ergometer until volitional fatigue. This is a validated surrogate for submaximal exercise tolerance. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Peak Oxygen Uptake (VO2max) | Measured at the beginning and end of each 4-week intervention period. | Maximum oxygen consumption (ml/kg/min) achieved during graded exercise testing. |
| Lactate Threshold | Measured at the beginning and end of each 4-week intervention period. | Workload or oxygen consumption corresponding to the point at which blood lactate concentration rises above baseline, assessed via graded exercise testing and gas exchange sampling. |
| Anaerobic Work Capacity | Measured at the beginning and end of each 4-week intervention period. | Cumulative work performed above the critical power, calculated from cycle ergometer testing. |
| Critical Power | Measured at the beginning and end of each 4-week intervention period. | The asymptote of the power-duration relationship. A work rate reflecting sustainable aerobic work capacity. |
| Circulating NAD+ and Related Metabolites | Measured at the beginning and end of each 4-week intervention period. | Plasma concentrations of NAD+, NMN, and related metabolites measured by targeted metabolomics. |
