Citrus Bergamot Extract vs NR (Nicotinamide Riboside)

Side-by-side comparison of mechanisms, dosing, interactions, and stacking potential.

Citrus Bergamot ExtractNR (Nicotinamide Riboside)
CategorySupplementsSupplements
Standard Dose300-600mg daily
TimingMorning with or without food.
Cycle Durationongoing
Evidence LevelModerate-StrongModerate-Strong

Mechanism

Contains brutieridin and melitidin — statin-like HMG-CoA reductase inhibitors from bergamot orange. Activates AMPK, improves lipid profiles (reduces LDL, increases HDL), and has antioxidant effects. Supports cardiovascular and metabolic health.

Contraindications

  • Rhabdomyolysis risk if combined with high-dose statins without monitoring

Mechanism

NR is converted to NMN by nicotinamide riboside kinases (NRK1/NRK2), then to NAD+ via the salvage pathway. Like NMN, elevated NAD+ activates sirtuins, PARPs, and CD38. NR has demonstrated ability to cross the blood-brain barrier and elevate brain NAD+ levels. It supports mitochondrial function, DNA repair, and circadian rhythm regulation through SIRT1-mediated deacetylation of BMAL1 and CLOCK proteins.

Standard Dosing

300-600mg daily

Timing

Morning with or without food.

Cycle Duration

ongoing

Side Effects

  • Mild nausea
  • Warmth/flushing (mild)
  • GI upset
  • Fatigue in some during initial days

Contraindications

  • Active cancer (same theoretical NAD+ concern as NMN)
  • Pregnancy/lactation
  • Theoretical cancer concern shared with NMN
