Product overview
Doctor's Best Vitamin C contains Q®-C (formerly called Quali®-C), which is manufactured in Scotland and prized for its quality and reliability. Besides its high quality, Q®-C has the lowest carbon footprint of all vitamin C on the market.
  • Essential vitamin and powerful antioxidant for immune system support.
  • Our bodies cannot produce vitamin C, so supplementation may be necessary to get the recommended daily amount.
  • Supports the body from free radicals, which can cause oxidative stress and may lead to other issues.
A better way to C
Vitamin C is indispensable to the body for its role in the synthesis of collagen, carnitine, and certain brain chemical transmitters. Studies show Vitamin C's fundamental support for the immune system, brain, eyes, heart and circulation and all organ systems. Vitamin C is a cofactor for important enzyme systems and supports joints and other connective tissues. It is an electron donor, supporting numerous enzymes and enhancing the body's total antioxidant potential. It also supports joints and other connective tissues. This potent antioxidant supports against free radical damage that influences the aging process, and is easily absorbed to support overall health and well-being.
How does it work?
Vitamin C is a key compound in the body's "antioxidant network," a chain of synergistic, inextricably linked, well-studied antioxidants that includes glutathione (GSH) and vitamin E. When vitamin E neutralizes free radicals it needs to be renewed. Vitamin C can change this status, by regenerating vitamin E back to its native form, and is thought to "spare" glutathione in the body as well.
