Why Buyers Choose Our Alpha Lipoic Acid

Transparent & Measurable Specifications
Every shipment is evaluated against strictly defined parameters (Assay, Heavy Metals, Residual Solvents, Particle Size, and Microbial Limits) rather than vague quality claims. This gives your quality control team a dependable baseline for incoming raw material inspection.

Batch-Specific COA & HPLC Verification
We supply a lot-specific Certificate of Analysis (COA) with every shipment, backed by validated High-Performance Liquid Chromatography (HPLC) testing. Buyers can request analytical raw data and testing protocols during supplier qualification.

Optimized Physical Characteristics for Formulation
Physical properties like bulk density, flowability, moisture level, and particle size directly impact your production process:

Capsules: Consistent particle size prevents dusting and ensures uniform filling.

Tablets: Controlled moisture and flowability optimize direct compression and binder compatibility.

Powder Blends: Custom particle sizing helps prevent segregation when mixed with vitamins or other botanicals.

FAQ

Q: What is Alpha Lipoic Acid and what are its primary uses?

A: Alpha Lipoic Acid (ALA / Thioctic Acid) is a potent sulfur-containing antioxidant compound. It is widely used in dietary supplements, daily multivitamins, and functional food formulations supporting metabolic health and cellular energy.

Q: What is the CAS number and specification standard for ALA?

A: The CAS number is 1077-28-7. Our standard product meets USP and EP pharmacopeia requirements with an assay of 99.0% to 101.0% on a dried basis.

Q: Can I request custom particle sizes for tableting or powder blends?

A: Yes. Depending on your formulation and process equipment, we can offer specific particle size distributions (e.g., fine powders or specific mesh sizes) to optimize flowability and uniform mixing.

Q: What regulatory and quality documents can you provide for vendor qualification?

A: We provide a full QA dossier including Batch COA, Product Specification, SDS, TDS, Allergen Statement, Non-GMO Statement, Halal/Kosher Certificates, and cGMP compliance documentation.

Q: How should bulk Alpha Lipoic Acid be stored during transit and warehousing?

A: ALA should be kept away from direct sunlight, moisture, and high heat. It should be stored in tightly sealed containers below 25°C in a temperature-monitored warehouse environment.
