CALCIUM CARBONATE & IT’S HISTORY Calcium carbonate is a common supplement, and most people know it as the brand Tums. Calcium supplements were invented in the 19th century. WHAT IS IT USED FOR? § Calcium can be used for either GI issues or to supplement the natural amount of calcium we are
supposed to consume from our diets. § GI: Sold under the common brand name Tums, calcium has FDA approved uses for relief of acid
indigestion, heart burn, upset stomach and other stomach issues. § Supplement: This can be used in those with low calcium levels, and those with conditions such as
osteoporosis, osteomalacia, hypocalcemia rickets. HOW DOES IT WORK? In the GI tract, calcium quickly neutralizes excess acid making it a popular supplement for upset stomach. As a supplement, the calcium is absorbed into the body and slows the decay of bone, especially in those with osteoporosis. DOSAGE FORMS AND DOSING § Calcium supplements are available in tablet form. For each gram of calcium carbonate, it has 400mg
of elemental calcium. § GI: dosing for stomach related issues is up to 8g of calcium carbonate per day for up to two weeks. § Supplementation: The dosage range varies from 500mg-4g of calcium carbonate per day, in 1-3 doses.
