Its fast-dissolving powder form allows for flexible dosing and rapid absorption, making it a trusted choice for professionals prioritizing clean, effective supplementation. ## 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.

It says on the Quali-C website that Quali-C is sourced from non-gmo cornfields. http://www.dsm.com/products/quali-c/en_US/about-quali-c/traceability.html **Q: Some people are saying this isn't real vitamin c, what is quali-c? why doesnt it dissolve in water?** A: The Vitamin C recommended by the Vitamin C Foundation is a Quali-C product, and a quick search of "ascorbic acid" shows it to be synonymous with Vitamin C, so the argument that Quali-C is not real Vitamin C seems untenable. As for its solubility in water, it dissolves almost instantly in hot water. **Q: Doctor's best is owned by a multi-national, food conglomerate company. how can i trust that this product is truly quali-c from scotland?** A: The label indicates it was manufactured in Scotland. Unless they are giving false information on the label, I will have to assume that it is true. I have been unable to find another vitamin c powder that is certified non-GMO that is not made in China from corn, it seems to work fine for me, no colds or flus or infections for over 2 years since I have been taking it. I suggest you contact Doctors Best directly with any questions, if you can trust what they tell you. Hope this is of help. The main thing is to avoid vitamins from China. **Q: Is this L-ascorbic acid?** A: We are happy to help. The Doctor's Best Vitamin C Powder is ascorbic acid using the branded Quali™-C. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Powerful Vitamin C *by N***E on February 18, 2026* I don’t Write reviews that often, For this product is a must..I’ve been taking since 2018 is definitely my go to for vitamin C powder.
