Feeling increasingly sluggish during workouts? Looking for that extra push to get through the day with more stamina? NAD+ might be a promising partner, with its ability to potentially improve endurance. Here’s how NAD+, a molecule naturally occurring in your body, can make a difference in your energy levels and overall vitality.
What Is NAD+?
Nicotinamide adenine dinucleotide (NAD+) is a critical coenzyme found in all living cells. It plays a pivotal role in energy production and cellular repair. Think of NAD+ as the fuel that keeps cellular engines running smoothly. It helps turn nutrients into cellular energy – ATP, through processes like the citric acid cycle, and supports over 500 enzymatic reactions.
How NAD+ Works Biologically
Biologically, NAD+ functions by facilitating electron transport in cellular processes, essentially acting as a shuttle to transfer energy within cells. This transfer is vital for efficient metabolism and cellular health. As we age, NAD+ levels decline, which has been linked to decreased energy and sluggish metabolic processes.
What Does the Human Evidence Say?
- Human RCTs: A few randomized controlled trials suggest that supplementing NAD+ precursors may increase NAD+ levels safely. For instance, a study indicated an enhancement in cellular NAD+ by over 50% when subjects took nicotinamide riboside (NR), a precursor, daily for 6 weeks.
- Cohort Studies: Observational studies find correlations between higher NAD+ levels and better endurance, but causation remains to be established.
- Mechanistic Insight: Animal models provide evidence that NAD+ augmentation can improve endurance and muscle function, though direct translation to humans needs further investigation.
| Study Type | Evidence Level | Summary Finding |
|---|---|---|
| RCT | High | Increased NAD+ levels; potential for improved energy |
| Cohort | Moderate | Association with better endurance but not causative |
| Mechanistic | Supportive | Evidential support for endurance enhancement in animals |
Practical Protocol
- Timing: NAD+ boosters, like NR, are typically taken once daily, on an empty stomach to optimize absorption.
- Stacks: Pairing NAD+ boosters with a balanced diet rich in B vitamins and antioxidants may further enhance benefits.
- Lifestyle Pairing: Regular physical activity can naturally elevate and preserve NAD+ levels, improving its efficacy.
Safety and Contraindications
Most studies report good tolerance at recommended doses (around 300 mg per day for adults). Nonetheless, consult a healthcare provider before initiating any supplementation, particularly if you have underlying health conditions.
How to Choose Quality
- Forms: Look for NAD+ precursors like nicotinamide riboside or nicotinamide mononucleotide (NMN).
- Standardization: Products should list NAD+ content standardized by weight.
- Testing: Opt for supplements with third-party testing certification for purity and potency.
The Bottom Line
NAD+ shows potential as a valuable player in boosting endurance and energy levels, though continued research is warranted.
