Why supplement?
Aspartate
Calcium aspartate uses aspartic acid as the ligand. Absorption talk follows an amino-acid path; evidence is mixed. The benefit is calcium, not an excitatory-amino-acid supplement.
Bone mineralization
Calcium aspartate is a source of calcium. Calcium makes up hydroxyapatite and is absorbed with vitamin D. This salt supplies elemental calcium; after adulthood, calcium alone cannot reverse an established osteoporotic image.
How to take it
A single serving is usually best kept to about 500 mg of elemental calcium.
How oftenPrefer food first and make up any gap from the product label; the usual adult total upper limit is 2,500–2,000 mg/day, depending on age.
What to watch
