Absorption: NMN and NR are the direct precursors. Niacin (B3) also raises NAD+ but with less specificity. Combining with resveratrol potentiates the effect via sirtuins.
Absorption:Caution: See individual precautions for NMN and NR. The concept of raising NAD+ is well supported but optimal methods are still debated.
Caution:Recommended doses
Range: 250 – 1000 mg
