Is NMN Safe? What Science Actually Says

Most studies show NMN is safe and well-tolerated in healthy adults—even at doses up to 500mg daily.

Reported side effects are mild and rare:

• Nausea
• Headache
• Digestive discomfort

Still, if you have chronic conditions, are pregnant, or on meds, talk to your doctor first. And go slow: start low, see how your body reacts.
