NAD+ is essential for energy production during exercise. Can supplementing with NAD+ precursors improve athletic performance?
NAD+’s Role in Exercise
1. Energy Production
During exercise, your muscles need massive amounts of ATP. NAD+ is critical for:
- Glycolysis (fast energy)
- Aerobic metabolism (sustained energy)
- Fat oxidation (endurance energy)
2. Mitochondrial Function
Mitochondria are the powerhouses of muscle cells. NAD+:
- Supports mitochondrial biogenesis (creating new mitochondria)
- Enhances mitochondrial efficiency
- Improves oxygen utilization
3. Recovery
NAD+ supports post-exercise recovery by:
- Reducing inflammation
- Supporting DNA repair
- Enhancing cellular repair processes
Research Findings
NMN and Exercise
2021 (Journal of the International Society of Sports Nutrition):
- 600mg NMN for 6 weeks
- Improved aerobic capacity in amateur runners
- Enhanced oxygen utilization
2023 (Frontiers in Nutrition):
- 1200mg NMN for 6 weeks
- Improved time to exhaustion
- Enhanced endurance performance
NR and Exercise
2020 (Cell Reports Medicine):
- NR supplementation in older adults
- Improved muscle NAD+ levels
- Enhanced exercise capacity
Protocol for Athletes
| Goal | NMN Dose | NR Dose | Timing |
|---|---|---|---|
| Endurance | 500-1000mg | 300-600mg | Morning |
| Strength | 500mg | 300mg | Pre-workout |
| Recovery | 500-1000mg | 300-600mg | Post-workout |
| General fitness | 250-500mg | 250-300mg | Morning |
Stacking for Performance
Pre-Workout Stack:
- NMN 500mg (energy)
- Caffeine 100-200mg (focus)
- Beta-alanine 3g (endurance)
Post-Workout Stack:
- NMN 500mg (recovery)
- Protein 25-30g (muscle repair)
- Creatine 5g (strength)
The Bottom Line
NAD+ supplementation shows promise for improving exercise performance, particularly:
- Endurance capacity
- Oxygen utilization
- Recovery speed
- Mitochondrial function
However, it’s not a magic pill. Combine with proper training, nutrition, and rest.
