Calcium ascorbate is considered a buffered mineral ascorbate, and is therefore less acidic. Mineral ascorbates are often recommended to people who experience gastrointestinal problems with plain ascorbic acid (vitamin C). When mineral salts of ascorbic acid are taken, both the ascorbic acid and the mineral appear to be well-absorbed, so it is important to take into consideration the dose of the mineral accompanying the ascorbic acid when taking large doses of mineral ascorbates.
Pure calcium ascorbate provides approximately 114 mg of calcium and 884 mg of vitamin C per 1 000 mg. The recommended dietary calcium intake for adults is 1 000–1 200 mg per day; total calcium intake should not exceed the tolerable upper intake level of 2 500 mg/d.
