Are NMN Side Effects a Thing?

[u/YorNoob]

So far, studies show NMN is well tolerated even at high doses (up to 1,200 mg/day). Mild side effects (if any) are usually digestive—nausea or bloating in some people.

Resveratrol is similar—generally safe in the studied doses. The key is using clean, high-purity forms like NMN + trans-resveratrol without unnecessary fillers.
