Most calcium supplements are poorly absorbed. As a result, calcium can build up in areas in the body other than the bones. Fortunately, we are aware of this. Global Healing’s Calcium & Magnesium contains a highly absorbable form of Calcium and Magnesium Orotate, which is very different that the average calcium supplement. This formula is in a 2:1 calcium-to-magnesium ratio to increase absorption. Calcium orotate has a high bioavailability and is delivered in smaller amounts to ensure you get where it is needed, to the bone. We generally recommend taking Calcium & Magnesium several hours (about 2-3 hours) away from Iron and Zinc to ensure maximum absorption.
