Product Description
R-Lipoic Acid is the naturally occurring enantiomer of alpha-lipoic acid, a sulfur-containing antioxidant compound used in nutraceuticals, dietary supplements, and functional nutrition formulations. It is supplied as a high-purity powder for manufacturers developing premium antioxidant products requiring the biologically active R-form of lipoic acid.
R-Lipoic Acid, also known as R-Alpha Lipoic Acid or (R)-Dihydrolipoic acid precursor, is the naturally occurring form found in biological systems. Compared with synthetic alpha-lipoic acid mixtures containing both R and S forms, R-Lipoic Acid provides a single stereoisomer format for specialized supplement development.
R-Lipoic Acid is the R-enantiomer of alpha-lipoic acid (ALA), a naturally occurring organosulfur compound involved in cellular energy metabolism. It contains a five-membered disulfide ring structure and is classified as a vitamin-like antioxidant compound.
Commercial R-Lipoic Acid is commonly produced through stereoselective synthesis or purification processes designed to obtain the naturally occurring R-isomer. It is typically standardized by assay purity and stereochemical content.

R-Lipoic Acid is widely used in capsules, tablets, and powder supplements designed around antioxidant and nutritional ingredient systems.
Manufacturers incorporate R-Lipoic Acid into advanced nutrition products requiring a purified, naturally occurring lipoic acid isomer.
R-Lipoic Acid can be combined with ingredients such as vitamins, minerals, and botanical antioxidants to create multi-component nutritional formulations.
For buyers sourcing R-Lipoic Acid, the most important specification factor is stereochemical purity. Alpha-lipoic acid exists as two optical isomers, R and S forms, and commercial products may differ depending on whether they contain a single isomer or a racemic mixture. Reliable chiral analysis helps confirm R-isomer content and ingredient consistency.
| Selection Factor | Why It Matters | Typical Buyer Consideration |
|---|---|---|
| R-Isomer Content | Defines the proportion of the naturally occurring active stereoisomer | Review chiral purity data and analytical specifications |
| Assay Purity | Indicates overall ingredient concentration | High-purity grades are commonly selected for premium supplements |
| Stability Control | Affects storage and formulation performance | Evaluate packaging, moisture protection, and storage conditions |
| Analytical Documentation | Supports ingredient qualification | Request COA, TDS, SDS, HPLC, and chiral analysis reports |
R-Lipoic Acid is commonly supplied in 1kg and 5kg aluminum foil bags or 25kg fiber drums for bulk ingredient handling. Customized packaging solutions can be arranged according to production, storage, and transportation requirements.
R-Lipoic Acid supports customized nutritional supplement development projects. OEM services may include ingredient blending, capsule and Tablet Manufacturing, powder processing, customized packaging, labeling solutions, and technical documentation support.
Typical quality control procedures for R-Lipoic Acid include:
R-Lipoic Acid is used as a specialty antioxidant ingredient in dietary supplements, functional nutrition products, and advanced nutritional formulations requiring a purified alpha-lipoic acid isomer.
R-Lipoic Acid is the naturally occurring R-enantiomer of alpha-lipoic acid, while standard alpha-lipoic acid products may contain a mixture of R and S isomers. The two forms differ in stereochemical composition.
R-Lipoic Acid quality is commonly evaluated through HPLC assay, chiral analysis, identity testing, moisture analysis, heavy metals testing, and other applicable quality procedures.
R-Lipoic Acid is a premium nutraceutical ingredient used in antioxidant supplements and functional nutrition products. With controlled R-isomer specifications, reliable analytical testing, and flexible bulk packaging options, it supports professional formulation development and ingredient sourcing.
