Doctor''s Best Vitamin C Q-C Supports Immune System Antioxidant 120 Capsules

SKU: 61718

1 Review(s) | Add Your Review

Doctor''s Best Vitamin C Q-C (Quali-C) delivers pure ascorbic acid sourced from Quali-C — a European-manufactured, pharmaceutical-quality vitamin C ingredient known for its rigorous purity standards and consistent potency. Quali-C is produced in Scotland by DSM under GMP pharmaceutical standards, which is a distinguishing quality marker from lower-cost ascorbic acid sources. Vitamin C (ascorbic acid) is an essential water-soluble antioxidant required for collagen synthesis, immune neutrophil function, iron absorption from plant sources, vitamin E recycling, and numerous enzymatic reactions. The 120-capsule bottle provides 2 to 4 months of supply depending on daily dose. Standard single doses of 500 to 1000 mg are well absorbed; split dosing (twice daily) improves plasma level consistency. Ascorbic acid is acidic — people with gastric sensitivity may prefer buffered vitamin C formulas (calcium ascorbate, sodium ascorbate). High-dose supplementation (2000+ mg) may increase urinary oxalate and should be used cautiously by people with kidney stone history.

Q: What is Quali-C and why is it a quality marker?

    A: Quali-C is a trademarked pharmaceutical-grade ascorbic acid manufactured by DSM Nutritional Products in Dalry, Scotland — one of the few vitamin C production facilities operating under pharmaceutical GMP (Good Manufacturing Practices) outside of China. The significance is consistency, purity documentation, and supply chain traceability. Most vitamin C supplements globally use ascorbic acid produced in China, which varies in quality control rigor. Quali-C provides certificates of analysis with traceable specifications. For consumers prioritizing ingredient sourcing quality and manufacturing transparency, Quali-C designation is a meaningful differentiator. Doctors Best is recognized for this ingredient-quality focus.

    A: The RDA is 75 to 90 mg daily for most adults — easily met from diet alone with adequate fruits and vegetables. For supplemental immune support, 500 to 1000 mg daily is widely used and well within safe limits. The body has saturation kinetics above 500 mg per dose — splitting doses (morning and evening) improves plasma concentration consistency better than a single large dose. The Tolerable Upper Intake Level is 2000 mg daily. For acute illness support, some practitioners recommend 1000 to 2000 mg per day short-term. Megadose protocols above 2000 mg should only be pursued with healthcare provider guidance, particularly for those with kidney concerns.

Q: Is there a difference between ascorbic acid and vitamin C?

    A: Ascorbic acid is the chemically pure form of vitamin C — they are the same molecule. Supplemental vitamin C is usually ascorbic acid or one of its salts (sodium ascorbate, calcium ascorbate). Whole-food vitamin C from fruits includes bioflavonoids (hesperidin, quercetin, rutin) alongside ascorbic acid — these co-factors may improve antioxidant activity and vascular health. Buffered forms (ascorbate salts) are gentler on the stomach than pure ascorbic acid — beneficial for those with gastric sensitivity. Liposomal vitamin C uses phospholipid encapsulation for enhanced absorption. For most people, pure ascorbic acid from a quality source like Quali-C is effective and well-tolerated.
