Doctor’s Best Vitamin C 500mg provides a focused daily source of an essential nutrient involved in antioxidant protection, immune function and collagen formation. Unlike many nutrients, vitamin C cannot be manufactured by the human body and must be obtained consistently through food or supplementation. This premium formula uses Q-C ascorbic acid, a quality-focused vitamin C ingredient produced in Scotland, inside a simple vegan capsule containing no added fillers beyond the capsule shell. With 120 veggie capsules and 500 mg per serving, it is designed for adults seeking dependable support for normal immunity, connective tissues, cellular antioxidant defenses and the absorption of iron from plant-based foods.
The Science of Vitamin C Optimization
Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin and an important physiological antioxidant. It also acts as a co-factor for multiple enzyme systems involved in collagen production, carnitine synthesis and normal neurotransmitter metabolism. Its value therefore extends beyond seasonal immune routines.
Antioxidant Activity: Vitamin C helps protect cells against oxidative stress by interacting with reactive compounds generated during normal metabolism and environmental exposure. It can also participate in the regeneration of other antioxidants, including vitamin E.
Collagen Co-Factor: Vitamin C is required for the hydroxylation processes involved in normal collagen formation. Collagen provides structural support to the skin, cartilage, blood vessels, bones and other connective tissues.
Immune and Iron Support: Vitamin C contributes to normal immune function and improves the absorption of nonheme iron, the form found mainly in plant foods. Pairing vitamin C with iron-containing meals may therefore support nutritional iron uptake.

Specifications
Usage Guide
Adults should take one capsule twice daily, preferably without food, or follow the advice of a nutritionally informed physician. The complete suggested daily intake provides 1,000 mg of vitamin C. If taking other multivitamins or antioxidant formulas, review their vitamin C content to avoid unnecessary duplication. Vitamin C may also be paired with plant-based iron foods or iron supplements because it supports nonheme iron absorption. Supplements should complement a varied diet that includes fruits, vegetables and other natural sources of vitamin C.
Safety Information
Do not exceed the recommended serving. The adult upper intake level for vitamin C from food and supplements is 2,000 mg daily unless a healthcare professional advises otherwise. Higher intakes may cause diarrhea, nausea or abdominal cramps. Consult a doctor before use if you are pregnant, breastfeeding, undergoing chemotherapy or radiation, using regular medication, managing kidney disease or prone to oxalate kidney stones. People with hereditary hemochromatosis or another iron-overload condition should also seek professional guidance because vitamin C increases nonheme iron absorption. Stop use and seek advice if an unexpected reaction occurs. Keep out of reach of children and store in a cool, dry place.
