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. ## Features - Best Vitamin C featuring Quali-C provides a brand of ascorbic acid manufactured in Scotland prized for its quality and reliability - Brand: Doctor's Best - Comes 1000 mg ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005CD3J4O | | ASIN | B005CD3J4O | | Age Range Description | Adult | | Allergen Information | Gluten Free | | Best Sellers Rank | #42,271 in Health ( See Top 100 in Health ) #265 in Vitamin C Supplements | | Brand Name | Doctor's Best | | Color | red | | Container Type | Bottle | | Customer Reviews | 4.8 4.8 out of 5 stars (8,043) | | Customer reviews | 4.8 4.8 out of 5 stars (8,043) | | Diet Type | Vegan | | Dosage Form | 1000 | | Flavor | vitamin c with qualic | | Global Trade Identification Number | 00753950002579, 00753950003842 | | Is Discontinued By Manufacturer | No | | Item Dimensions | 6.7 x 6.7 x 12.7 centimeters | | Item Form | Capsule | | Item Highlight | Vegan Vitamin C Capsules as Q-C Ascorbic Acid, Immune Health Support for Adults, Non GMO, Gluten Free, Soy Free | | Item Weight | 0.4 Pounds | | Item model number | DRB-00257 | | Manufacturer | Doctor's Best | | Manufacturer | Doctor's Best | | Manufacturer Part Number | DRB-00257 | | Material Type Free | en_AE | | Model Name | Doctor's Best Non-GMO, Vegan | | Model Number | DRB-00257 | | Number of Items | 1 | | Primary Supplement Type | Carnitine | | Product Benefits | Immune Support | | Product Dimensions | 6.68 x 6.68 x 12.7 cm; 181.44 g | | Special Ingredients | Vitamin C contains Quali-C | | Specific Uses For Product | Healthy Immune System, Antioxidant | | UPC | 753950002579 301653928452 753950003842 | | Unit Count | 120 Count | ## Product Details - **Brand:** Doctor's Best - **Diet type:** Vegan - **Flavour:** vitamin c with qualic - **Item form:** Capsule - **Primary supplement type:** Carnitine ## Images ![Doctor's Best, Vitamin C, Featuring Quali-C, 1000 mg, 120 Veggie Caps - Image 1](https://m.media-amazon.com/images/I/61kDn9vumHL.jpg) ## Available Options This product comes in different **Flavor Name, Size** options. ## Questions & Answers **Q: What does vitamin C do?** A: Extensive clinical research confirms the crucial role of Vitamin C in supporting the immune system, brain, eyes, heart, circulation, and overall organ health.* **Q: How many should I take daily?** A: Take 1 capsule daily preferably without food, or as recommended by a nutritionally informed physician. **Q: What makes Q-C special?** A: Q-C (Quali-C) is what makes this Doctor's Best Vitamin C special - it's a premium brand of ascorbic acid manufactured in Scotland that's prized for its high quality and reliability. **Q: Best time to take vitamin C?** A: For the Doctor's Best Vitamin C, here's the optimal timing for best absorption: Morning on an empty stomach is ideal - vitamin C is best absorbed without food interference. **Q: How long will it last?** A: The Doctor's Best Vitamin C contains 120 capsules per bottle.
