SynergyInsufficient evidence
What is happening. Vitamin C is a water-soluble antioxidant that can recycle the oxidized ubiquinone moiety back to its reduced ubiquinol form, complementing MitoQ's lipid-phase antioxidant activity within mitochondrial membranes. The aqueous and membrane antioxidant networks can act cooperatively to regenerate active antioxidant species.
Mechanism. Ascorbate participates in redox cycling that can reduce ubiquinone to ubiquinol, helping regenerate the active reduced form of the MitoQ quinone group at the membrane interface.
Recommendation. No special precaution is needed. This is a low-risk, plausibly complementary pairing of aqueous-phase and membrane-phase antioxidants. Use standard doses of each.
