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.3 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. Review: Consistent Quality and Immune Support with Doctor’s Best Vitamin C - I’ve been taking vitamin C supplements for over a decade and have tried various brands. A few years ago, I learned about Quali-C, a high-quality form of ascorbic acid manufactured in Scotland by DSM. Since then, I’ve been specifically seeking out supplements that use this ingredient, and Doctor’s Best Vitamin C has been my go-to choice. One of the standout features of this product is its use of Quali-C, which is renowned for its purity and reliability. This gives me confidence in the supplement’s effectiveness. I take one capsule in the morning and another in the evening. Since adopting this routine, I’ve noticed a significant decrease in the frequency of colds. The capsules are easy to swallow and gentle on the stomach, even when taken on an empty stomach. This is particularly beneficial for those with sensitive digestive systems. Additionally, the product is non-GMO, vegan, gluten-free, and soy-free, aligning with various dietary preferences. Overall, Doctor’s Best Vitamin C with Quali-C provides consistent quality and effectively supports my immune health. I highly recommend it to anyone looking for a reliable vitamin C supplement.
