Description

3-Hydroxybutanoic Acid Magnesium Salt is a bio-based, water-soluble magnesium salt of the ketone body β-hydroxybutyrate. This compound matters for its role as a highly bioavailable source of magnesium and the ketone body BHB, supporting metabolic and physiological functions. It is needed by manufacturers in the nutraceutical, pharmaceutical, and functional food industries for formulating advanced dietary supplements and specialized medical nutrition products.

Application

• Nutraceutical & Dietary Supplements: As a key ingredient in magnesium and exogenous ketone supplements for supporting energy metabolism, cognitive function, and athletic performance.
• Pharmaceutical Intermediates: Used in the synthesis of advanced therapeutic agents and as an active pharmaceutical ingredient (API) in specialized formulations.
• Functional Food & Beverage Fortification: For enriching health drinks, meal replacements, and functional foods with bioavailable magnesium and ketone bodies.
• Medical Nutrition: A component in clinical nutrition products designed for metabolic management, neurological support, and specific dietary therapies.
• Cosmetic & Personal Care: Potential use in skincare formulations for its moisturizing and skin-barrier supporting properties.
• Research & Development: Serves as a standard or reagent in biochemical, metabolic, and nutritional research studies.
