Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that naturally occurs in fruit and vegetables.
Vitamin C naturally occurs in fruit and vegetables, such as citrus fruits, strawberries, kiwi, peppers, and broccoli.
Prolonged release, also called sustained release, means that a tablet is formulated so that the active ingredients are gradually released, instead of all at once.
A regular tablet generally releases the active ingredient all at once after ingestion. A tablet with sustained release is formulated so that the ingredient is released gradually, over a longer period.
Ascorbic acid is the most commonly used, pure form of vitamin C. Calcium ascorbate is a buffered form in which the acid is bound to calcium.
