Product Overview
R-Alpha Lipoic Acid is the R-isomer form of Alpha Lipoic Acid and is commonly supplied as a yellow crystalline powder for supplement, nutrition, and formulation projects that specifically require R-ALA.
It may also be identified as R-(+)-Alpha Lipoic Acid or R-Thioctic Acid. For commercial sourcing, buyers should confirm not only chemical purity or assay, but also the required R-isomer identity and the analytical basis used to verify the material.
R-Alpha Lipoic Acid should be distinguished from standard Alpha Lipoic Acid and from Sodium R-Lipoate. Standard ALA represents the conventional commercial ALA route, while Sodium R-Lipoate is the sodium salt of R-Alpha Lipoic Acid and should be evaluated as a separate product form when specifically required by the formulation or specification.
Applications
Capsules & Tablets
R-Alpha Lipoic Acid may be used in capsule and tablet formulations where the product specification specifically requires the R-isomer form of Alpha Lipoic Acid. Buyers should confirm assay, R-isomer identity, particle characteristics, and processing requirements before scale-up.
Powder Blends & Premixes
For dry blends and premix systems, R-ALA may be selected when the finished formulation or customer specification calls for a defined R-isomer ingredient. Blending behavior, particle characteristics, and content uniformity should be evaluated according to the formulation.
Functional Nutrition Formulations
R-ALA may be used in functional nutrition and specialty formulation projects where the R-isomer is specifically required by the finished-product specification, formulation design, or customer requirement.
Specification-Driven Projects
For projects based on an existing formula, reference COA/TDS, customer specification, or defined R-ALA requirement, the exact chemical identity, assay basis, stereochemical requirement, and physical form should be confirmed before sampling or quotation.
How to Choose the Right Grade / Form
Choose Standard Alpha Lipoic Acid when:
Your formulation does not specifically require the R-isomer and a conventional Alpha Lipoic Acid raw material is acceptable for the project.
Choose R-Alpha Lipoic Acid when:
Your specification, formulation, or customer requirement specifically calls for the R-isomer of Alpha Lipoic Acid in the free-acid form.
Choose Sodium R-Lipoate / Na R-ALA when:
Your project requires the sodium salt of R-Alpha Lipoic Acid rather than the free-acid R-ALA form. This route should be treated as a separate product specification and evaluated against the relevant COA or technical requirement.
Selection Guidance
If an existing formulation, reference COA/TDS, or customer specification is available, use that document to confirm the required chemical form before requesting a sample or quotation.
Technical & Formulation Notes
Technical Notes
R-Isomer Identity
R-Alpha Lipoic Acid is the R-isomer of Alpha Lipoic Acid. For commercial sourcing, the required stereochemical identity should be confirmed together with chemical purity or assay.
Free-Acid Form
This product refers to free-acid R-Alpha Lipoic Acid rather than Sodium R-Lipoate. The exact chemical form should be confirmed before sample approval or quotation.
Product Identification
R-Alpha Lipoic Acid may also be identified as R-ALA, R-(+)-Alpha Lipoic Acid, or R-Thioctic Acid in technical and commercial documentation.
Storage Protection
Store the material in sealed packaging under the conditions specified by the supplier, with protection from heat, moisture, and prolonged exposure during storage and handling.
Manufacturing & Process
Powder Processing
R-ALA powder should be evaluated according to the intended manufacturing process, including feeding, blending, transfer, and downstream handling requirements.
Material Handling
Handling conditions should be reviewed according to the intended dosage form, manufacturing process, and required batch consistency.
Processing Conditions
Processing temperature, exposure time, and moisture conditions should be considered during formulation development and scale-up.
Scale-Up Evaluation
Laboratory or pilot evaluation is recommended when R-ALA is introduced into a new formulation or manufacturing process with defined technical requirements.
Compatibility / Formulation Notes
Particle Size & Flowability
Particle characteristics and flowability should be evaluated according to the intended capsule, tablet, premix, or dry-blend process.
Blending & Uniformity
For multi-ingredient powder systems, blending behavior and uniform distribution should be considered during formulation development and scale-up.
Ingredient Compatibility
Compatibility with other formulation components should be evaluated according to the composition, dosage form, and processing conditions of the finished product.
Form Selection
If the formulation specifically requires a sodium salt rather than free-acid R-ALA, Sodium R-Lipoate should be evaluated as a separate product route.
Formulation Evaluation
Pilot or laboratory testing is recommended where the formulation has specific processing, stability, or performance requirements.
Extended QC & Test Items
Identity & Assay
Product identity and chemical assay or purity should be confirmed against the applicable COA and agreed specification.
R-Isomer / Enantiomeric Identity
For R-ALA sourcing, the required R-isomer identity and applicable analytical basis should be confirmed in addition to general chemical purity.
Related Substances & Impurities
Related-substance or impurity testing should be reviewed according to the required grade, specification, and analytical method.
Physical Characteristics
Appearance, particle size, and other physical parameters may be included where they are relevant to processing or finished-product requirements.
Additional Quality Tests
Depending on the application and agreed specification, review may also include moisture-related parameters, residual solvents, heavy metals, microbiological limits, or other market-specific test items.
