NMN: what the evidence actually shows

surging NMN — anti-aging hype far ahead of any human outcome data

Reviewer and governance status are shown on each atomic claim below.

What it is

NMN is tracked as a health intervention in this evidence graph. Also known as: nicotinamide mononucleotide.

Studied forms and doses

No form-specific catalog record is available. This does not mean all forms are equivalent.

blood sugar: 250-2000 mg/day, 14 days to 12 weeks in the reviewed trials; form not reported.

Mechanisms

Mechanistic plausibility is context, not proof that a clinical outcome improves.

No structured mechanism is recorded.

⚠ Safety in context

No interaction record is modeled for this intervention. This is an unknown coverage state, not evidence that no interaction exists.

Products and verification

No product label snapshot is mapped in this released catalog. Ingredient evidence does not establish any bottle’s identity, potency, purity, availability, or value.

Evidence by outcome

blood sugarstudied, no effectlow certainty— Review of 8 human RCTs (342 mainly non-diabetic middle-age/older adults, 14 days to 12 weeks, 250-2000 mg/day): NMN supplementation showed no significant benefit on fasting glucose, fasting insulin, HbA1c, insulin resistance (HOMA-IR), or lipid profile. Short-term NMN supplementation did not meaningfully improve glucose control in this population.
