Is dehydroascorbic acid bad?

Vitamin C is metabolized to dehydroascorbic acid, which is then oxidized to oxalic acid and its prolonged use, especially in high doses, can increase propensity to form renal stones due to relative hyperoxaluria, crystalluria, and hematuria [88].

dehydroascorbic acid The oxidation of vitamin C, ascorbic acid, is brought about by the loss of two hydrogen atoms as the vitamin is converted to dehydroascorbic acid.

What is the difference between ascorbic acid and dehydroascorbic acid?

Dehydroascorbic acid is made from the oxidation of ascorbic acid. This reaction is reversible, but dehydroascorbic acid can instead undergo irreversible hydrolysis to 2,3-diketogulonic acid.
