Intervention of Nicotinamide Mononucleotide in Middle-aged and Elderly People
Condition(s) studied
AgingNMN
Investigational drug(s) / intervention(s)
NMNplacebo
NMN: NMN Arm participants took one capsule (containing 350mg NMN or placebo) with breakfast daily for one year.
placebo: Placebo arm participants took one capsule (appearance and odor are the same as NMN) with breakfast daily for one year.
Study summary
This study is a single-center, randomized, double-blind, placebo-controlled clinical trial investigating a pharmacological intervention for aging. Its primary objective is to evaluate the efficacy of NMN while ensuring the safety of oral administration, with the aim of identifying effective strategies to delay aging and improve the quality of life in the elderly population. The main outcomes of this study are to characterize the patterns of NMN efficacy across different populations and to identify sensitive biomarkers that reflect responsiveness to the intervention.

Primary outcome measure(s)
- Comprehensive evaluation of NMN in reducing biological age — Baseline, 6 months and 12 months
Change in biological age from baseline to 12 months, quantified using predefined multi-layer aging clock(s).
Biological age will be assessed using the following measures:
1. Transcriptomic age (years)
2. DNA methylation age (years)
3. Proteomic age (years)
4. Metabolomic age (years)
5. Phenotypic age (years)
The primary endpoint will be defined as:
Change from baseline to 12 months in a prespecified composite biological age score, derived from the above aging clocks using a predefined integration method (e.g., standardized z-score aggregation or principal component-based integration).
A reduction in biological age is defined as a decrease in the composite biological age score.
