Colostrum (Bovine)

Supplements

Mechanism

First milk containing immunoglobulins (IgG, IgA, IgM), lactoferrin, growth factors (IGF-1, TGF-beta), and proline-rich polypeptides. Seals gut barrier, modulates immune function, enhances mucosal immunity, and supports muscle recovery via growth factors.

Contraindications

  • Dairy allergy
  • Milk protein sensitivity

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)
