NAD+ levels decline 50% between ages 20 and 40.
By 2026, the market is flooded with boosters.
But are they worth it?
What is NAD+?
| Aspect | Details |
|---|---|
| Full Name | Nicotinamide Adenine Dinucleotide |
| Role | Cellular energy production |
| Decline | 50% drop by age 40 |
| Impact | Affects 500+ enzymatic reactions |
The Booster Options
| Type | How It Works | Cost |
|---|---|---|
| NMN | Direct NAD+ precursor | $60-100/mo |
| NR (Niagen) | Converts to NMN then NAD+ | $40-60/mo |
| Niacin (B3) | Older pathway, causes flush | $5/mo |
| NAD+ IV | Direct injection | $500/session |
✅ The Pros
1. Energy Restoration
| Aspect | Details |
|---|---|
| Effect | Sustained energy without stimulants |
| Mechanism | NAD+ is essential for ATP production |
| Timeline | 2-4 weeks for noticeable effects |
2. Genetic Repair
| Aspect | Details |
|---|---|
| Sirtuins | NAD+ fuels these longevity genes |
| PARPs | DNA repair enzymes need NAD+ |
| Impact | Better daily DNA damage repair |
3. Insulin Sensitivity
| Study | Finding |
|---|---|
| 2025 Human Trial | NMN improved insulin sensitivity |
| Effect | Mimics some benefits of fasting |
| Best For | Pre-diabetic, metabolic syndrome |
❌ The Cons
1. Methylation Depletion
| Problem | Solution |
|---|---|
| High doses deplete methyl groups | Take TMG (Trimethylglycine) alongside |
| Can affect mood, energy | 500mg-1g TMG daily |
2. Cost
| Issue | Reality |
|---|---|
| Quality NMN is expensive | $60-100/month minimum |
| Cheap alternatives | Often degraded niacinamide |
| Amazon gamble | Skip unknown brands |
3. Cancer Concerns?
| Question | Answer |
|---|---|
| Does NAD+ fuel cancer? | It fuels all cells, including potential cancerous ones |
| Evidence of causing cancer? | No direct evidence |
| Recommendation | Those with active tumors should avoid |
| Precaution | Screen before starting high-dose protocol |
NMN vs NR Comparison
| Factor | NMN | NR |
|---|---|---|
| Conversion Steps | Direct to NAD+ | NMN → NAD+ |
| Absorption | Debated, seems good | Well-studied |
| Cost | Higher | Lower |
| Research | More animal data | More human trials |
| Our Take | Slight edge | Solid alternative |
The Verdict
| Age Group | Worth It? |
|---|---|
| Under 30 | Probably not (still have high NAD+) |
| 30-40 | Consider if budget allows |
| 40+ | Data leans heavily YES |
| 60+ | Strong recommendation |
Best Practices
- Source quality — Buy from reputable brands
- Add TMG — Support methylation
- Take with fat — Better absorption
- Morning dose — Circadian alignment
- Combine with lifestyle — Sleep, exercise, fasting
