Description

R-α-Lipoic Acid Tromethamine Salt is a high-purity, stabilized salt form of the biologically active R-enantiomer of α-lipoic acid, a potent antioxidant and metabolic cofactor. This specific formulation offers enhanced stability and solubility compared to the free acid, making it a preferred ingredient for advanced nutraceutical and pharmaceutical applications. It is primarily utilized by manufacturers in the dietary supplement, cosmeceutical, and research sectors seeking a reliable, high-quality source of this critical bioactive compound.

Application

• Dietary Supplements: A key active ingredient in high-end antioxidant, metabolic support, and anti-aging formulations, often marketed for cellular energy and neurological health.
• Pharmaceutical Intermediates: Serves as a critical starting material or active pharmaceutical ingredient (API) in the development of prescription medications targeting diabetic neuropathy and other oxidative stress-related conditions.
• Cosmeceuticals & Skincare: Incorporated into serums, creams, and lotions for its potent antioxidant properties, helping to protect skin from environmental damage and support a more youthful appearance.
• Clinical & Biomedical Research: Used as a standardized reagent in laboratory studies investigating mitochondrial function, redox biology, insulin signaling, and neuroprotection.
• Veterinary Nutraceuticals: Formulated into supplements for companion and performance animals to support metabolic health and combat oxidative stress.
• Functional Food & Beverage Fortification: Employed in the enrichment of specialized health drinks and food products where enhanced stability is required.
