Most people are deficient in Calcium.
The daily needs for Calcium range from 1000 mg to 2000 mg per day but the average diet contributes only 500 mg per day. The problem with the typical Calcium supplement is that so little of it is absorbed. The most popular supplement is Calcium Carbonate from oyster shells. Instead of addressing the problem of Calcium deficiency they take toxic drugs instead. Calcium Carbonate can also cause gas and acid rebound.
