Standard Dose
Timing
Cycle Duration
Evidence LevelModerate (healthspan), Emerging (human longevity)Moderate

Mechanism

AKG is a TCA cycle intermediate that declines with age. Supplementation reduces inflammatory cytokines, improves stem cell function, and extends healthspan in mice. Calcium salt form provides sustained release. Also supports collagen synthesis and reduces frailty markers.

Contraindications

  • Hypercalcemia
  • Kidney stones (calcium component)
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
