About Bio C 1:1 – 90 Capsules

Optimize your daily wellness routine with Bio C 1:1 from Xymogen, a thoughtfully crafted formula pairing high-potency vitamin C with a standardized, full-spectrum citrus bioflavonoid complex. Both ingredients have been extensively researched for their complementary roles in supporting overall health.

Vitamin C is an essential nutrient required for the synthesis of collagen—the building block of healthy connective tissue and blood vessels—as well as for the production of key neurotransmitters and carnitine, a molecule vital for energy metabolism.* The addition of citrus bioflavonoids provides more than just antioxidant support; research indicates these compounds function as cell-signaling agents that support healthy metabolism and cognitive function.*

Delivered in a balanced 1:1 ratio, this professional-grade formula provides foundational support for your immune system, promotes healthy tissue integrity, and helps combat oxidative stress. As with all Xymogen products, Bio C 1:1 is made with high-quality ingredients and is free from common allergens, ensuring a clean and effective supplement for daily use.
