Vitamin C is an essential micronutrient that the body cannot produce itself. It is obtained from food, primarily fruits and vegetables, and is vital for the formation of hormones, collagen, and the immune system. Vitamin C acts as a powerful antioxidant and helps control inflammation. Conventional ascorbic acid powder is acidic and partially broken down in the stomach. It has lower stability and a shorter residence time in the blood and immune cells. In contrast, HBN Vitamin C+ contains calcium L-ascorbate, a buffered form with a neutral pH. This form is non-acidic and remains in white blood cells for up to 24 hours. Studies show that calcium ascorbate achieves higher vitamin C levels in leukocytes and, at 1000 mg doses, delivers 1.3–1.7 times more vitamin C to cells than pure ascorbic acid. In another clinical study, calcium ascorbate increased plasma levels more than placebo and ensured sustained vitamin C storage in immune cells. At 500 mg, phagocytosis by neutrophils and the number of natural killer cells also improved. Simultaneously, the buffered form is gentler on the stomach and causes less stomach or upper abdominal discomfort. Vitamin C+ from HBN Supplements provides 1000mg of calcium ascorbate per serving (1g of powder), of which 820mg is pure vitamin C. The powder contains no additives. The daily serving is dissolved in 200ml of water and taken. The powder form allows for individual, precise dosing.
