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

Combination that restores glutathione synthesis. Age-related glutathione deficiency is driven by glycine and cysteine precursor depletion, not enzyme dysfunction. GlyNAC corrects oxidative stress, mitochondrial dysfunction, inflammation, and insulin resistance in older adults.

Contraindications

  • Active stomach ulcer (NAC)
  • Asthma (NAC may cause bronchospasm in rare cases)
