What is happening. Vitamin C is a water-soluble antioxidant that can regenerate other oxidized antioxidants and complements the free-radical scavenging and Nrf2-mediated effects of ellagic acid, providing overlapping antioxidant coverage.
Mechanism. Complementary antioxidant network activity: vitamin C operates in the aqueous phase and can recycle oxidized polyphenol intermediates, while ellagic acid contributes phenolic radical scavenging and endogenous antioxidant enzyme induction.
Recommendation. These can reasonably be taken together for general antioxidant support; no special separation is required. There is no need to megadose either to obtain the additive effect.
