What Is Alpha Lipoic Acid Powder?
Alpha Lipoic Acid Powder is a sulfur-containing compound commonly sourced as ALA or thioctic acid for dietary supplement manufacturing.
Alpha Lipoic Acid Powder is also called ALA, thioctic acid, DL-thioctic acid or 1,2-dithiolane-3-pentanoic acid. In supplement raw material sourcing, Alpha Lipoic Acid may be supplied as a racemic DL-ALA material, R-Alpha Lipoic Acid, stabilized Sodium R-Lipoate or other project-specific forms. Buyers usually evaluate Alpha Lipoic Acid by CAS number, chemical identity, assay, isomer profile, melting range, appearance, particle size, residual solvents, loss on drying, heavy metals, microbiology, solubility, light sensitivity, packaging and destination market label requirements.
Defined Chemical Identity
ALA sourcing should confirm CAS number, chemical name, molecular formula, assay method and batch documentation before supplier approval.
Isomer Form Review
DL-ALA, R-ALA and stabilized R-ALA salt are not identical sourcing choices and should be compared by identity and COA.
Supplement Supply Focus
Gensei supports supplement brands, OEM factories and contract manufacturers with bulk Alpha Lipoic Acid sourcing and technical documentation.
Alpha Lipoic Acid Specification Options
Final specifications depend on ALA form, assay target, isomer profile, particle size, purity standard, packaging, stability and destination market requirements.

Applications in Dietary Supplements
Gensei supplies Alpha Lipoic Acid Powder mainly for supplement and specialty nutrition projects rather than medical, pharmaceutical, cosmetic or therapeutic applications.
Formulation Notes for Supplement Brands
ALA selection should be aligned with form, assay target, dosage format, solubility strategy, taste profile, packaging, stability and destination market compliance.
Form & Isomer Profile
Confirm whether your formula requires DL-ALA, R-ALA or stabilized R-ALA salt before approving the raw material.
Assay & Purity
Review assay, chromatographic purity, melting range, residual solvents, loss on drying and related substances by batch COA.
Light & Moisture Protection
ALA should be protected from light, heat and moisture through suitable packaging, storage and finished-product stability design.
Solubility Strategy
Drink powders, sachets and gummies should be tested for water dispersibility, sediment, taste, pH and active uniformity.
Taste & Odor Review
ALA contains sulfur groups, so gummies, chewables and powders should be tested for sulfur note, bitterness and flavor compatibility.
Supplement Facts Review
Final ALA amount, ingredient name, serving size, warnings and other label details should be confirmed by the brand owner.
