Full Rapamycin profileNAD+
NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a pyridine dinucleotide coenzyme essential to energy metabolism, DNA repair via PARP enzymes, sirtuin-mediated gene regulation, and calcium signaling via CD38.…

| Attribute | Rapamycin | NAD+ |
|---|---|---|
| Category | Longevity | Longevity |
| Research Stage | Preclinical | Phase II |
| Mechanism of Action | Rapamycin's mechanism of action centers on its inhibition of the mechanistic target of rapamycin (mTOR), a central serine-threonine kinase that integrates nutrient, growth factor, and stress signals to regulate cellular growth, protein synthesis, autophagy,… | Redox Cofactor Function NAD+ serves as the primary electron acceptor in catabolic reactions (glycolysis, TCA cycle, fatty acid oxidation), cycling between its oxidized (NAD+) and reduced (NADH) forms. This fundamental energy metabolism role means every cell… |
| Half-Life | — | Varies by form: NR ~8 hours plasma; NMN ~1-2 hours plasma; IV NAD+ infusion dose-dependent |
| Typical Dose Range | — | Oral precursors: NR 300-2,000 mg/day, NMN 250-900 mg/day, NAM 500-1,500 mg/day; IV NAD+ 500-1,500 mg per session. |
| Dosing Frequency | — | Oral precursors once daily (higher doses split AM/midday); IV NAD+ weekly-to-monthly at clinics. |
| Administration | — | Oral (precursors), Intravenous, Intramuscular, Subcutaneous |
| Side Effects | Rapamycin has a well-characterized side-effect profile developed over decades of transplant use. The profile at longevity doses (weekly 5-8 mg) is substantially milder than at transplant doses (continuous daily dosing targeting 5-15 ng/mL trough levels), but… | Nicotinamide Riboside (NR) NR has the best-characterized safety profile of the NAD+ precursors. Across published RCTs at 1,000-2,000 mg/day for up to 12 weeks, adverse effects have been mild and uncommon: - Gastrointestinal upset (5-10% of users) - Mild… |
| Molecular Weight | — | 663.4 g/mol (NAD+); NR 255.3 g/mol; NMN 334.2 g/mol; NAM 122.1 g/mol |
| Common Vial Sizes | — | 100mg, 250mg, 500mg |

Rapamycin: potential benefits
- No structured benefit list published.
NAD+: potential benefits
- Restores age-associated NAD+ decline — 50% loss between young and older adulthood
- Whole-blood NAD+ up 22, 51 and 142 percent at 100, 300 and 1,000 mg NR a day in an 8-week trial (Conze 2019, PMID: 31278280)
- Supports sirtuin-mediated gene regulation and PARP-mediated DNA repair
- Improves muscle insulin sensitivity in prediabetic postmenopausal women (Yoshino 2021)
- Increases aerobic performance in amateur runners at 300-600 mg NMN (Liao 2021)
- IL-6, IL-5 and IL-2 lower than baseline after 21 days of NR in 12 older men (PMID: 31412242)
- Brain NAD+ elevation demonstrated in Parkinson trial (Brakedal 2022)
- Excellent safety profile at evidence-supported doses (500-2000 mg/day NR)
Frequently asked
What's the difference between Rapamycin and NAD+?
Rapamycin is a longevity that rapamycin's mechanism of action centers on its inhibition of the mechanistic target of rapamycin (mtor), a central serine-threonine kinase that integrates nutrient, growth factor,…. NAD+ is a longevity that redox cofactor function nad+ serves as the primary electron acceptor in catabolic reactions (glycolysis, tca cycle, fatty acid oxidation), cycling between its oxidized (nad+) and…. The two differ in mechanism, half-life (not reported vs Varies by form: NR ~8 hours plasma; NMN ~1-2 hours plasma; IV NAD+ infusion dose-dependent), and typical dose range.
Which has the longer half-life, Rapamycin or NAD+?
Rapamycin has a half-life of not reported. NAD+ has a half-life of Varies by form: NR ~8 hours plasma; NMN ~1-2 hours plasma; IV NAD+ infusion dose-dependent. Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
Can you stack Rapamycin and NAD+?
Stacking depends on mechanism overlap, safety profile, and goals. Rapamycin and NAD+ should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds.
