NMN for Insulin Resistance: What the Evidence Actually Shows

Category: metabolic | ICD-10: E88.81 | Evidence tier: preliminary-human

What is Insulin Resistance?

Insulin resistance is when muscle, fat and liver cells respond poorly to insulin, forcing the pancreas to compensate. It precedes Type 2 diabetes and contributes to fatty liver and PCOS.

NMN relevance: the published evidence

Yoshino 2021 is the cleanest human signal: 250 mg/day for 10 weeks improved skeletal-muscle insulin signalling in prediabetic postmenopausal women. Mouse data (Mills 2016) align. Effect size is modest and the population studied is narrow. Do not assume the same benefit applies to men or younger women.

Questions to ask before supplementing

250 mg/day per Yoshino 2021.

Contraindications and red flags

Pair with diet and resistance training; supplements alone rarely fix insulin resistance.

Bottom line for Malaysian patients

NMN is not registered with NPRA as a treatment for any specific condition; it is sold as a general health supplement. If you have insulin resistance, use this page as a question list for a registered medical practitioner before adding NMN to existing therapy. Read our safety guide for full red-flag context.
