The study provides crucial insights into NAD+'s cardiovascular benefits.

Key Findings:

Energy Homeostasis: Central role in cellular energy and redox balance

DNA Repair: Critical for maintaining cellular integrity

Cardiovascular Protection: NAD+ replenishment shows protective effects

Risk Factor Mitigation: Addresses aging, obesity, and hypertension-related decline

Blood NAD+ Increase: Measurable elevation in circulating NAD+ levels

Anti-Aging Potential: Supporting evidence for aging-related benefits

This comprehensive update reviewed multiple human clinical trials of NMN supplementation. The study noted that NAD+ concentration in human skin, blood, liver, muscle, and brain are thought to decrease with age, and NMN supplementation increases NAD+ concentration and could mitigate aging-related disorders such as oxidative stress, DNA damage, neurodegeneration, and inflammation. The review represents the most current safety and efficacy data available.

Key Findings:

Multi-Tissue NAD+ Decline: Age-related NAD+ reduction across multiple organs

Oxidative Stress Reduction: Protection against cellular damage
