Documented Uses

There is no approved indication for dehydroascorbic acid, but it has potential therapeutic use in patients with certain viruses and ischemic stroke.
Organic substances that are required in small amounts for maintenance and growth, but which cannot be manufactured by the human body.
Even though dehydroascorbic acid and ascorbic acid have similar effects, their mechanism of action seems to be different. The exact mechanism of action is still being investigated, but some have been elucidated. Concerning dehydroascorbic acid's antiviral effect against herpes simplex virus type 1, it is suggested that dehydroascorbic acid acts after replication of viral DNA and prevents the assembly of progeny virus particles.
Aromatic L-Aminoacid Decarboxylase Deficiency
Dopamine beta-hydroxylase deficiency
Monoamine oxidase-a deficiency (MAO-A)
