2.2 Cardiovascular Protection

• Lipid Regulation:
  • ALA suppresses hepatic lipogenesis via AMPK activation, reducing LDL-C by 15–20% in preclinical models.
  • Oxidative Defense: Rich in tocopherols (85mg/kg α-tocopherol) and phenolic acids (ferulic acid: 12mg/kg).

2.3 Metabolic Syndrome Support

• PPAR-γ Activation: GLA enhances insulin sensitivity by upregulating adiponectin expression (plasma levels increased by 18% in pilot studies).

3. Safety Protocols & Contraindications

• Dilution Guidelines:
  • Topical: 1–3% in carrier oils (jojoba, argan) | Oral: 500–1000mg/day (softgel formulation).
