Can Vitamins Cause Bloating?

While bloating is not a common side effect of any one vitamin, some vitamin interactions, vitamin deficiencies and malabsorption may cause it. Other symptoms may include burping, gas and constipation. Certain vitamins can be helpful in treating bloating if it is associated with a deficiency-related illness. To rule out other conditions that cause bloating, such as allergies and irritable bowel syndrome, consult a doctor for an examination before taking any treatment supplements.

Multivitamins

According to Healthwise, multivitamins and iron supplements also cause bloating. This information regards both prescription- and nonprescription-grade vitamins as well as dietary supplements. Stop using the vitamin supplements to rule them out as the cause of bloating. Contact a doctor and describe your symptoms for treatment options.

Malabsorption

Malabsorption is inability to absorb or difficulty in absorbing nutrients and vitamins. Malabsorption symptoms include bloating, cramping and gas. Vitamin B-12 deficiency and numerous diseases also cause malabsorption. According to MedlinePlus, some of the causes include cholestasis, HIV, Crohn's disease and chronic liver disease. Malabsorption treatment consists of vitamin and nutrient replacement. If you think you have symptoms of malabsorption, consult a doctor immediately.

Treatment

Conversely, certain vitamins can treat bloating. Vitamin B-6 helps reduce bloating and water retention in the body by increasing metabolism. Lora Rice, author of "The Everything Guide to Food Remedies," says vitamin B-6 supplements in combination with calcium can effectively reduce bloating.

Supplements

The brain and organs need essential supplements such as omega-3 fatty acids, which the body can't produce, and dietary fiber. University of Maryland Medical Center says fish oil can cause bloating. Other symptoms include belching, diarrhea and gas. Timed-release preparations may reduce the side effects. Buy omega-3 vitamins from a reputable supplier to ensure mercury and pesticide residue are not in the vitamins. Fiber supplements that contain psyllium can also cause bloating, particularly when consumed too quickly.

Considerations

MedlinePlus recommends avoiding chewing gum and carbonated drinks, particularly those high in fructose and sorbitol. Brussels sprouts, cabbage, turnips, beans and lentils can cause bloating. Smoking and eating quickly may contribute to bloating. If bloating persists after you have stopped taking vitamin supplements, it is likely caused by another condition and usually accompanied by abdominal pain, vomiting and constipation. Consult a doctor before self-treating your bloating symptoms.
