A

Apigenin

Supplements

Mechanism

Flavonoid (found in chamomile, parsley) that inhibits CD38, the primary NAD+-consuming enzyme. Also a potent aromatase inhibitor and anxiolytic via GABA-A modulation. Supports NAD+ levels, reduces estrogen conversion, and improves sleep quality.

Contraindications

  • Caution in pregnancy (uterotonic potential at high doses)
B

Urolithin A

Supplements

Mechanism

Gut metabolite of ellagitannins that activates mitophagy — selective clearance of damaged mitochondria. Improves mitochondrial function, muscle endurance, and cellular energy production. Only ~40% of population can produce it endogenously.

Contraindications

  • Limited long-term safety data beyond 4 months
