Carbonated beverages come in many forms, such as seltzer water and soft drinks. Many doctors and dentists caution against drinking these in large amounts because of the ingredients they contain. Previously held beliefs that carbonated beverages can lower calcium levels in the body, weaken bones and increase the risk of breakages or chronic conditions like osteoporosis lack sufficient evidence.

Traditional Belief

Research does not support traditional beliefs that carbonated beverages drain the body of calcium or that the caffeine in certain drinks also prevents the body from properly absorbing calcium into the body and the bones.

Confirmed Effects

Modern research has greatly diminished the perceived negative effects of carbonated beverages on your calcium levels. According to Health Services at Columbia University, research has found little, if any, relationship between the phosphorus found in carbonated beverages and the depletion of calcium from the body. The large amounts of sugar in carbonated beverages represent a much more influential culprit.

Replacing Calcium

If you allow carbonated beverages to replace calcium-containing drinks like milk, they can deplete your body's calcium levels. Milk, with its high amount of calcium, as well as other fortified calcium drinks, supports bone health. In addition to sugar, the sodium in carbonated beverages makes them an unhealthy choice. Limit your consumption of these beverages and eat several servings of of calcium-rich foods each day.


If you do drink carbonated beverages and have concerns about your body's calcium intake, taking calcium supplements daily can bolster your body's health and improve bone density and strength. Take calcium in doses of 500 to 600 milligrams, spreading multiple doses out throughout the day, because the body does not absorb larger doses effectively. Check with your doctor beforehand to make sure calcium supplements will not adversely interact with medications or medical conditions.
