Not all forms of Calcium are equal. The form you choose determines how much Calcium actually reaches your tissues, and the difference between the best and worst forms can be substantial. Calcium bisglycinate chelate absorbs effectively without food and without competing with other minerals — unlike calcium carbonate which requires stomach acid and competes with iron and zinc. The chelated form also avoids the constipation commonly associated with carbonate forms, improving long-term adherence.
