Types of Vitamin C materials
- L-Ascorbic Acid (acidic; crystalline/fine powder)
- Sodium L-Ascorbate (neutral, easy to handle)
- Calcium L-Ascorbate (provides minerals too)
- Coated grades (improved stability / sustained release)
Main uses
Widely used for nutritional fortification in supplements and as an antioxidant in beverages and processed foods. Salt types or coated grades are chosen for acidity and stability reasons.

FAQ
What if the acidity is a concern?
Consider sodium or calcium salts, or coated grades, to reduce acidity and irritation.
Which form is good for tableting?
Grades with good particle size and flowability, or coated grades, perform well in tableting.
Does Vitamin C degrade easily?
It degrades via oxidation and moisture, so coated grades and controlled storage are effective.
