Our ALA is manufactured under GMP standards with high purity, ensuring consistent performance for dietary supplements, pharmaceuticals, and cosmetics.
Dual-soluble antioxidant: works in both aqueous and lipid phases.
Supports glucose metabolism and insulin sensitivity.
Protects nerve cells and supports neurological health.
Helps regenerate other key antioxidants.
High Purity: ≥99% pharmaceutical-grade Alpha Lipoic Acid.
