Vitamins play a big role in the health of bariatric patients. It is important for patients to understand why and how certain supplements work in their bodies so they can reap the full benefits in the most efficient way.
The mineral calcium plays a very important role in the human body and is necessary for the normal growth and development of bone, teeth, muscle, enzyme and nerve functions. After bariatric surgery, the body’s ability to absorb calcium can be reduced. Therefore, all patients are strongly encouraged to take a calcium supplements daily not only to prevent deficiencies but additionally because increased calcium intake has been linked to enhanced weight loss.
There are two common forms of calcium: calcium citrate or calcium carbonate. Calcium carbonate depends heavily upon stomach acid absorption. Calcium citrate does not require stomach acids to digest and absorb. With the alterations to the stomach that occur during surgery, it is important to remember to take calcium citrate instead of calcium carbonate to maximize your supplement benefit.
Studies have shown that calcium in the citrate form was absorbed 22 percent to 27 percent more effectively than calcium in the carbonate form. I recommend my bariatric patients take 1,800 mg of calcium citrate throughout the day but divided into doses no larger than 600 mg. Therefore, most patients will be required to take their calcium three times per day. This can become complicated given the doses need to be separated by two hours from iron supplements or other calcium supplements to allow the body to absorb the vitamin’s nutrients. If patients take the vitamins at the same time they will compete for absorption and the body will pass what is unable to be absorbed.
