NMN

Nicotinamide mononucleotide (NMN) is being investigated for several clinical applications, though the evidence base remains limited with most studies still in early phases or preclinical stages.

Cardiovascular Health

Preclinical research suggests NMN may help address metabolic dysfunction in heart cells. One 2026 study found that NMN ameliorated damage caused by high glucose and high fat conditions in cardiomyocytes through SIRT1-mediated mechanisms, indicating potential applications for metabolic heart disease.

Neurological Conditions

Multiple preclinical studies are exploring NMN's potential in neurological applications:

• Stroke/Brain Injury: A 2026 study examined combination therapy with NMN and elamipretide for post-ischemic brain injury in mice, targeting specific inflammatory pathways
• Alzheimer's Disease: Research is investigating NMN's role in targeting cellular death pathways associated with Alzheimer's disease
• Neural Development: Studies suggest NMN may support neural progenitor cells through NAD+ pathway modulation

Reproductive Health

Clinical trials are investigating NMN for fertility-related conditions:

• A clinical trial (NCT05485610) is examining NMN's effects on diminished ovarian reserve and premature ovarian insufficiency, though results are not yet available
• Preclinical research suggests NMN may help restore sperm motility when combined with other compounds

Aging and Longevity

Several studies focus on NMN's potential anti-aging effects:

• Bone health research indicates NMN may help restore NAD+ homeostasis for aged bone repair
• The PROMETHEUS clinical trial protocol includes NMN as part of a broader investigation into healthy aging interventions
• Studies on immune function include trials examining NMN's effects on peripheral blood immune cells and dendritic cell function (NCT05984550, NCT06036355)

Current Clinical Trial Status

Most human clinical trials with NMN are either completed without published results or have unknown status. One completed trial (NCT04571008) examined NMN's effects on organ system biology, but detailed findings are not yet publicly available.

Important Limitation: The clinical evidence for NMN remains largely preclinical, with limited published human trial data. Most applications are still investigational, and the safety and efficacy profiles in humans require further study.
