Evidence Summary

Nicotinamide Riboside (NR) is an NAD+ precursor that has been shown to effectively increase NAD+ levels in various populations, including healthy older adults and those with specific metabolic or muscle conditions. Research primarily focuses on its ability to augment the NAD+ metabolome and its potential anti-inflammatory effects.

Evidence by Condition

Chronic supplementation is well-tolerated and effectively elevates NAD+ levels in healthy middle-aged and older adults.

NR augments the NAD+ metabolome in aged human skeletal muscle and induces anti-inflammatory signatures.

Oral NR supplementation raises NAD+ and lowers certain biomarkers of neurodegenerative pathology in plasma extracellular vesicles.

Small-scale studies suggest NR combined with pterostilbene can increase NAD+ levels in AKI patients.

COPD Insufficient

Research is investigating the effect of NR on airway inflammation in COPD patients.

Werner Syndrome Insufficient

Clinical trials are exploring the benefits of NR supplementation in patients with this rare progeroid syndrome.

Effective Doses

Specific dose ranges were not explicitly detailed in the provided research abstracts.

Key Findings

  • Chronic NR supplementation is well-tolerated and elevates NAD+ in healthy middle-aged and older adults (PMID: 29599478)
  • NR augments the aged human skeletal muscle NAD+ metabolome and induces anti-inflammatory signatures (PMID: 31412242)
  • Oral NR raises NAD+ and lowers biomarkers of neurodegenerative pathology in plasma extracellular vesicles (PMID: 36515353)
  • NR with pterostilbene increases NAD+ in patients with acute kidney injury (PMID: 32791973)

Limitations

Much of the current evidence is limited by small sample sizes in specific clinical populations (e.g., AKI) and a primary focus on NAD+ elevation rather than long-term clinical outcomes.

Safety & Interactions

Long-term administration of NIAGEN (NR chloride) has been demonstrated to be safe in healthy overweight adults (PMID: 31278280).

Frequently Asked Questions

What is Nicotinamide Riboside and how does it work?

Nicotinamide Riboside (NR) is a precursor to NAD+, a molecule essential for cellular function. There is strong evidence that NR supplementation can effectively increase NAD+ levels in healthy middle-aged and older adults.

Does Nicotinamide Riboside help with muscle aging?

There is moderate evidence that NR can support aged human skeletal muscle. Research indicates it can augment the NAD+ metabolome and induce anti-inflammatory signatures in the muscle.

Can Nicotinamide Riboside help with neurodegenerative diseases?

There is moderate evidence that oral NR supplementation can raise NAD+ levels and lower certain biomarkers of neurodegenerative pathology in the blood. However, more research is needed to confirm its full impact.

Is Nicotinamide Riboside safe to take long-term?

Chronic supplementation of NR is considered well-tolerated in healthy adults. Specifically, long-term administration of NIAGEN (NR chloride) has been demonstrated to be safe in healthy overweight adults.
