L-Ascorbic Acid is the pure acid form with a sour taste and pH of approximately 2.5 in solution. Sodium Ascorbate is the buffered, sodium salt form — pH neutral, non-acidic, and less irritating to the gastric mucosa, making it suitable for individuals with acid sensitivity. Sodium Ascorbate provides approximately 889 mg Vitamin C per gram (vs 1000 mg/g for pure Ascorbic Acid). Calcium Ascorbate is another buffered form preferred in formulations requiring mineral fortification. We supply L-Ascorbic Acid as standard; other forms available on request.

Ascorbic Acid is one of the most oxidation-sensitive vitamins. Key degradation factors: oxygen exposure, metal ion catalysis (Fe²⁺, Cu²⁺), high temperature, high moisture, and alkaline pH. Stabilisation strategies include: packaging in nitrogen-purged, moisture-barrier containers; use of antioxidant synergists (EDTA to chelate metal ions); coating with Ethylcellulose or HPMC film to reduce moisture uptake; formulating at pH 4–6; and using Ascorbyl Palmitate (fat-soluble form) for oil-based formulations. Effervescent Vitamin C formulations are particularly stable as the dry anhydrous environment minimises oxidation.

Linus Pauling famously advocated doses of 1,000–10,000 mg/day for immunity and cancer prevention. Current evidence shows: the immune benefits are clinically relevant primarily in physically stressed populations (athletes, people in cold environments) at 200–1000 mg/day; megadoses above 2,000 mg/day offer no additional benefit over 200–400 mg and increase risk of kidney oxalate stones and GI distress; plasma Vitamin C saturates at approximately 200 mg/day oral intake. The recommended therapeutic range for immunity support in most evidence-based guidelines is 200–1,000 mg/day.

Yes. Vitamin C (Ascorbic Acid) dramatically enhances non-haem iron absorption by reducing insoluble Fe³⁺ to soluble Fe²⁺ and chelating iron in a form that remains soluble at intestinal pH. Studies show that 100–200 mg of Vitamin C taken simultaneously with iron supplements can increase iron absorption by 2–4×. This is the basis for combination iron + Vitamin C pharmaceutical products, which are standard in iron-deficiency anaemia treatment, particularly in India where dietary iron deficiency is widespread.
