R-Alpha-Lipoic Acid — Supplement Grade
Allzone Trading supplies R-Alpha-Lipoic Acid as a yellow crystalline powder or sodium salt to manufacturers and formulators in Canada and international B2B markets. Also referenced as R-ALA, R-(+)-lipoic acid, Na-RALA. R-alpha-lipoic acid is the naturally occurring enantiomer of lipoic acid. Free R-ALA has a low melting point and polymerises under heat and moisture, so the stabilised sodium salt form is often used where processing conditions are demanding.

Technical & procurement detail
What R-Alpha-Lipoic Acid is and what it does+
R-alpha-lipoic acid is the naturally occurring enantiomer of lipoic acid. Free R-ALA has a low melting point and polymerises under heat and moisture, so the stabilised sodium salt form is often used where processing conditions are demanding.
R-ALA and racemic ALA are different products+
Racemic alpha-lipoic acid contains the S enantiomer and is substantially cheaper. Specify R-ALA explicitly and require enantiomeric purity data, since the assay alone will not distinguish them.
Heat and moisture cause polymerisation+
Free R-ALA can soften and polymerise during hot processing or humid storage, producing a sticky, discoloured mass. Where that risk exists, ask for the stabilised salt form.
Documentation and specification+
Assay, particle size, solvent residue, microbiological limits and heavy-metal limits differ between producers and grades. Allzone confirms the applicable specification with the supplier before quoting and shares the technical data sheet, safety data sheet and certificate of analysis for the exact material offered, so the values you evaluate are the values you receive.
Frequently asked questions
What documentation is provided?+
