Product Overview
Alpha-Lipoic Acid (ALA), also known as Thioctic Acid (CAS 1077-28-7), is a nutritional ingredient commonly used in dietary supplement manufacturing. It is typically supplied as a yellow to pale-yellow crystalline powder.
Commercial ALA is commonly supplied as a mixture of R- and S-enantiomers. Buyers requiring R-Alpha-Lipoic Acid (R-ALA) should specify this separately, as the two ingredient types are not interchangeable for every formulation.

Applications & Formulation Considerations
Capsules & Tablets
Alpha-Lipoic Acid is widely used in dietary supplement capsules and tablets, including single-ingredient and combination formulations.
Manufacturers should consider powder particle size, flow properties, excipient compatibility, and content uniformity when selecting an ingredient grade for encapsulation or tableting.
Nutritional Premixes & Sports Nutrition
ALA can be incorporated into multi-ingredient nutritional blends and selected sports nutrition formulations.
For powder blending, formulators should assess the compatibility of ALA with other ingredients, mixing uniformity, and stability under the intended storage conditions.
Solubility & Processing Stability
Conventional Alpha-Lipoic Acid has limited water solubility and is sensitive to heat and light.
These properties are relevant when developing liquid products, high-temperature processes, or formulations requiring extended storage stability. Application-specific formulation testing is recommended.
Ingredient Selection & Quality Considerations
Conventional ALA vs. R-Alpha-Lipoic Acid
Conventional Alpha-Lipoic Acid generally refers to a racemic mixture of R- and S-lipoic acid. R-Alpha-Lipoic Acid contains the R-enantiomer and may be supplied in different chemical forms, including its sodium salt.
Buyers should confirm the required ingredient identity and form before comparing quotations, particularly when a finished-product formulation specifies R-ALA rather than conventional ALA.
Quality Evaluation
For bulk ingredient procurement, important quality parameters may include:
- Assay: Confirm the declared purity and analytical method.
- Identity: Verify the required Alpha-Lipoic Acid form.
- Related Substances: Review relevant impurities and degradation products.
- Physical Properties: Check appearance, particle size, and applicable moisture limits.
- Storage Requirements: Evaluate conditions for maintaining product stability.
ANADYO can provide a COA with Specifications for quality review.
Halal Documentation
A Halal certificate is available upon request for the offered Alpha-Lipoic Acid product.
For buyers in markets with specific Halal certification requirements, the certificate's issuing body, product coverage, validity, and local recognition should be checked against the intended destination market.
FAQ
Can I use conventional ALA instead of R-ALA in an existing formulation?
Not automatically. Conventional ALA and R-ALA differ in their stereochemical composition. Any substitution should be evaluated against the finished-product formulation, ingredient specification, and applicable quality requirements.
What information is needed to request a quotation?
Please provide your required quantity, destination country, and any specific assay, technical, or certification requirements. This helps ANADYO match the appropriate supply and documentation.
