The need for additional vitamin C (ascorbic acid) rises during periods of emotional, psychological or physiological stress as urinary excretion of the nutrient increases. The functions of vitamin C in the human body are very diverse. Vitamin C participates in the synthesis of collagen, the major protein from which connective tissue, cartilage, bone, skin, tendon, and tooth dentin is made*
- Acts as an antioxidant*
- Nourishes the adrenal glands and helps with stress response*
- Works to optimize absorption of nonheme iron*
- Supports normal immune function*

Each ¼ tsp serving contains:
Vitamin C (as Ascorbic Acid)
Description: Vitamin C (also known as ascorbic acid) is a potent water-soluble antioxidant and essential in the human diet as it cannot be synthesized within the body . Vitamin C is an electron donor, and this property is closely related to all of its known functions .
Uses: The stability and formation of collagen, the major protein from which connective tissue, cartilage, bone, skin, tendon, and tooth dentin is made, requires a vitamin C-mediated process . A lack of vitamin C, a required cofactor for prolylhydroxylase, impairs development of collagen and renders humans scorbutic . The human phenotype of vitamin C deficiency, scurvy, classically involves fragility of blood vessels .
In addition to its antiscorbutic action, vitamin C has potent antioxidant properties. Ascorbic acid can inhibit oxidative modification of LDL, in vitro, indicating a role for vitamin C in the maintenance of healthy circulation . Vitamin C has other anti-inflammatory effects including decreased leukocyte adhesion to the endothelium and increased bioavailability of atheroprotective nitric oxide (NO) . In response to physical trauma, vitamin C exerts a protective effect on neutrophil-mediated cell injury by scavenging reactive oxygen metabolites .
Vitamin C concentrations in plasma and leukocytes rapidly decline during infections and stress . Multiple clinical studies have shown that supplementation of vitamin C improves components of the human immune system; these include, but are not limited to, antimicrobial and natural killer cell activities, lymphocyte proliferation, chemotaxis, and delayed-type hypersensitivity .
Of the organs with high concentrations of vitamin C in the body, the adrenal glands, both cortex and medulla, notably accumulate significant levels of ascorbic acid . Animal models have shown the role of vitamin C in these tissues is crucial to survival . Ascorbic acid is a cofactor required both in catecholamine biosynthesis and in adrenal steroidogenesis .
For those consuming plant-based diets (no animal tissue), vitamin C is the only known dietary constituent that can significantly increase the absorption of nonheme iron . It is important to note, the stimulating influence of ascorbic acid on iron absorption has been demonstrated to be most pronounced when ascorbic acid is given with food .
