A

Pterostilbene

Supplements

Mechanism

Dimethylated analog of resveratrol with 4x greater oral bioavailability. Activates SIRT1 and AMPK, reduces oxidative stress, and improves lipid profiles. Superior pharmacokinetics compared to resveratrol due to methyl groups protecting against glucuronidation.

Contraindications

  • Hormone-sensitive conditions (mild estrogenic activity)
B

TUDCA

Supplements

Mechanism

Hydrophilic bile acid that stabilizes hepatocyte membranes, supports bile flow, and reduces endoplasmic reticulum stress. Often used in higher-load liver support and lipid-heavy protocols.

Contraindications

  • Caution with active gallbladder obstruction
