Plant compounds from citrus fruits that enhance vitamin C absorption and provide antioxidant, anti-inflammatory, and vascular support benefits.
CoQ10 (Ubiquinone/Ubiquinol)
Ubiquinol is the reduced, active form of CoQ10 that plays a critical role in cellular energy production via the mitochondrial electron transport chain and serves as a lipid-soluble antioxidant. It is more bioavailable than standard ubiquinone (oxidized CoQ10), particularly in aging populations.
