Mechanism

Phospholipid concentrated in brain cell membranes. Supports neurotransmitter production (acetylcholine, dopamine), cortisol regulation, and membrane fluidity. Improves cognitive function, reduces exercise-induced cortisol, and supports HPA axis recovery.

Contraindications

  • Soy allergy (if soy-derived — use sunflower-derived instead)
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.
