What Is Ascorbic Acid Powder?
Water-soluble Vitamin C, L-enantiomer, is essential for collagen production, immunological function, and antioxidant defence. Unlike produced equivalents, our pure crystalline powder eliminates industrial concerns such oxidative degradation during storage and low pH stability in liquid compositions.
It’s active form is directly involved in the enzymatic hydroxylation processes essential for the generation of the collagen triple-helix. You will have a better antioxidant capacity . React with the reactive oxygen species ( ROS ) and regenerate additional antioxidants like Vitamin E .
