Dehydroascorbic Acid Buy Now

Because DHA is highly unstable in liquid form, it is primarily sold as a high-purity powder for laboratory and manufacturing use rather than as a standard retail supplement.

: In the context of topical serums, the presence of DHA (indicated by a change to orange or brown color) usually signifies that the product has oxidized and lost its antioxidant efficacy. In these cases, it may even act as a pro-oxidant, potentially irritating the skin.

: DHA is significantly less stable than L-ascorbic acid. It is often shipped as a lyophilized (freeze-dried) powder and must be stored at temperatures as low as -20°C to prevent further decomposition into 2,3-diketogulonic acid. dehydroascorbic acid buy

Dehydroascorbic acid (DHA) is the oxidized form of Vitamin C (ascorbic acid). While it is often viewed as a sign of degradation in consumer skincare products, it serves as a critical research compound due to its unique ability to cross the blood-brain barrier. Sourcing Dehydroascorbic Acid

: Unlike standard Vitamin C, DHA is actively transported into cells via glucose transporters (GLUTs). Once inside, the body typically reduces it back into active ascorbic acid. Because DHA is highly unstable in liquid form,

: For high-grade chemical needs (96% purity or higher), specialized distributors like Thermo Fisher Scientific and Sigma-Aldrich offer DHA in milligram quantities. These products are typically designated for research use only.

: While rare as a standalone consumer product, some specialized formulations, such as the Virt-C DHA prescription dietary supplement, incorporate DHA precursors or metabolites under medical supervision. Key Considerations for Buyers : DHA is significantly less stable than L-ascorbic acid

: Companies like GoldBio and Cayman Chemical provide molecular biology grade DHA, often used in studies involving glucose transport and cellular oxidative potential.
