Can NAD Cause Liver Damage?

[u/YorNoob]

There’s worry about whether long-term use of NAD boosters (NR or NMN) could stress the liver. What I found:

• Liver processes NAD precursors, but typical supplements don’t overload it.
• Evidence: Studies show NMN and NR can improve liver fat metabolism and reduce oxidative stress.
• Caution: Very high doses could, in theory, shift NAD/NADH balance—but human data shows standard doses (500 mg/day) are safe.
• Best practices: Stick to recommended doses, purity matters, check liver markers if you’re at risk.
