Product Information
Alpha Lipoic Acid Powder
Also known as Thioctic Acid, Alpha Lipoic Acid is a sulfur-containing ingredient used in nutritional formulations. Gensei supplies it as a slightly yellow crystalline powder for manufacturers developing or producing finished supplement products.
Alpha Lipoic Acid, Also Known as Thioctic Acid
The material supplied is Alpha Lipoic Acid rather than a separately specified lipoic acid form. Its chemical identity and analytical requirements give formulation, quality and purchasing teams a clear basis for raw-material approval.

Applications
Alpha Lipoic Acid Powder for Nutritional Formulations
Alpha Lipoic Acid powder works naturally with many dry supplement formats and can also be evaluated for more complex delivery systems during product development.
Capsules
A practical choice for single-ingredient or multi-ingredient capsule formulas, where Alpha Lipoic Acid can be incorporated into a dry powder blend before filling.
Tablets
Suitable for tablet projects developed around a compatible excipient system and manufacturing process.
Powder Blends
Can be used in multi-ingredient powder systems where consistent distribution through the finished blend is required.
Gummies & Chewables
May also be considered for gummies and chewable products when the formulation and manufacturing process are developed around the ingredient.
Formulation
Working with Alpha Lipoic Acid Powder
When moving from raw material to finished product, the complete formula matters. Alpha Lipoic Acid should be evaluated together with the excipients, other active ingredients and processing conditions used in the final dosage form.
Capsules, Tablets & Dry Blends
In dry formulations, the goal is consistent distribution and practical handling through the chosen production process. The behavior of the complete blend is more useful than judging the active ingredient in isolation.
- Check blend uniformity before scaling production.
- Evaluate flow and handling with the actual excipient system and process.
- Build the processing approach around the finished dosage form.
Gummies, Chewables & Other Formats
These formats usually involve a more complex matrix and different processing conditions than a dry capsule blend. Small-scale development work can help show how Alpha Lipoic Acid behaves before the formula moves into commercial production.
- Use the actual finished-product matrix during development.
- Account for the processing conditions used in production.
- Verify the finished formula before commercial scale-up.
