Does NMN have side effects?Updated 3 days ago
Great question!
For most people, NMN is well-tolerated and does not cause any side effects when taken at recommended doses. It's a naturally occurring molecule already found in your body and in trace amounts in foods like broccoli and avocado.
However, some people may experience mild and temporary effects, especially when starting NMN for the first time. These may include:
Mild nausea or digestive discomfort
Headaches (rare)
Fatigue if taking too late in the day (due to cellular energy regulation)
These symptoms are uncommon and usually resolve as your body adjusts.
💡 Pro tip: Taking NMN in the morning with food may help reduce the chance of any mild discomfort and align better with your body’s natural energy rhythm.
If you’re on medications or have health conditions, it’s always wise to consult your healthcare provider before starting any new supplement — just to be safe.
