## Description

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.

## Questions & Answers

**Q: What is the absorbing acid made from?  Why not use a fruit acid?**
A: First of all it's Ascorbic acid.  This particular Vitamin C is a brand of ascorbic acid made by DSM which is the last and only Western producer of vitamin C!  All their vitamin C is produced in a world-class DSM-owned facility in Dalry, Scotland. In fact, DSM/Roche was the first company to synthesise vitamin C back in 1938, and has been a leading producer for over 75 years.  Quali®-C is the world’s first branded vitamin C, and buying it guarantees you the peace of mind you can only get from the best supplier.  Also, to further clarify, Ascorbic acid is found in citrus fruits as well as citric acid, but citric acid does not contain Vitamin C.
Ascorbic acid is natural, citric acid is man-made, hence, synthetic.  If you want more in-depth information though about this particular product, visit this website:

**Q: It is bitter and tart (very acidic)? i saw reviews of other vitamin c powder of quali-c is very tart and acidic, causing heart burn and hard on tummy.**
A: I have not had this experience and I take 3 grams most days

**Q: Where are this made ?It does not say it anywhere.**
A: It is made in the US.  Doctor's Best is now owned by the Kingdomway Group, a publicly traded company in China.  According to an article I read the primary reason Kingdomway purchased Doctor’s Best was to provide an authentic, manufactured in the USA brand to the rapidly expanding market in Asia.

**Q: No stearate or stearic acids is wonderful however it does not contain rose hip, isnt that a requirement for vitamin c absorbtion can anyone clearify?**
A: Definitely not a requirement. Vitamin C is water soluble, meaning all it needs for absorption is water. Most vitamin C supplements don't contain rose hips.
