  • BEST VITAMIN C with Q-C - Vitamin C is an essential health nutrient, with many important functions in the body, immune system, antioxidant and tissue healing.* Known as a natural antioxidant that supports the immune system and helps with iron absorption. As a powerful antioxidant, vitamin C acts as an election donor that helps fight oxidation, a chemical reaction that produces unwanted free radicals.
  • IMMUNE SYSTEM SUPPORT – Vitamin C supplements is known as a natural antioxidant that supports the immune system and helps with iron absorption. Potent antioxidant that protects the body against oxidative challenges. Provides the potent antioxidant, Vitamin C, that neutralizes damaging free radicals produced by stress and exposure to toxins, that can damage your body.*
  • ESSENTIAL FOR MULTIPLE FUNCTIONS - Vitamin C is nutrient essential for bones, joints and other connective tissues. Vitamin C is essential for collagen fiber synthesis, a process vital for tissue repair and healing.

Ascorbic acid is invaluable to the body for its role as an electron donor, supporting numerous metabolic enzymes in addition to enhancing the body's total antioxidant potential.*

Vitamin C is a key compound in the body’s “antioxidant network,” a chain of
synergistic, inextricability linked, well-studied antioxidants that includes
glutathione (GSH) and vitamin E. When vitamin E uses its antioxidant function
in neutralizing free radicals, it also loses this antioxidant function.
Vitamin C can change this status; it can regenerate vitamin E back to its
native form, and is thought to “spare” glutathione in the body as well.
Importantly, when ascorbate donates an electron and becomes itself oxidized,
or “consumed,” the ascorbate radical is relatively harmless. In a double-
blind, placebo-controlled study in which blood GSH was measured in healthy
subjects at several stages, 500 mg of vitamin C taken daily for 2 weeks
significantly raised erythrocyte (red blood cell) glutathione levels. The
researchers concluded that vitamin C supplementation at that level can benefit
the overall antioxidant capacity of the blood. In another study of similar
design, 1000 mg of vitamin C taken daily for 4 weeks bolstered vitamin E and
glutathione content in erythrocyte cell membranes, compared with placebo. The
highest concentrations of vitamin C in the body are found in the central
nervous system (in neurons of the brain & spinal cord) and the adrenal glands.
Although the presence of ascorbate in neurons is in part explained by its
neuromodulatory enzyme activity, its high concentration suggests that vitamin
C is so greatly retained by neurons in order to address the higher rates of
oxidative metabolism experienced by the brain. This has led to the conclusion
that under normal conditions, vitamin C helps safeguard the integrity of
neurons (and therefore the brain), largely through neutralization of the free
radicals of reactive oxygen species (ROS). Low levels of blood vitamin C and
the resulting accumulation of ROS are thought to be detrimental—especially to
aging populations.
