Idebenone is shown to have properties similar to CoQ10’s antioxidant benefits. Idebenone is different from Coenzyme Q10 in one very important way. During a hypoxic (low oxygen) condition, CoQ10 can switch function from an anti-oxidizing to an auto-oxidizing process. This auto-oxidation rapidly produces free radicals which can damage the tissues of the body. Idebenone is shown to perform the same functions as CoQ10 without the risk of an auto-oxidation reaction.
Idebenone is said to promote nerve growth factors in the brain. It appears to reduce tinnitus (ringing in the ears) and shown in topical applications to treat wrinkles.
