Most Common Side Effects Of Dietary Supplements

Stomach Cramps

Gastrointestinal issues such as stomach cramps, abdominal pain, and heartburn are common side effects of several vitamins, herbs, and minerals. For example, arginine can increase stomach acid, and vitamin B6 and cocoa supplements are sometimes associated with stomach irritation as well. Zinc, a mineral found in numerous multivitamins, could contribute to stomach cramps in certain patients, and many patients get stomach cramps when taking iron. To reduce the risk of stomach cramps and pain when taking supplements, patients could try taking an enteric-coated supplement, and they might also wish to ask their doctor about alternative supplement formulas that could be easier on the stomach. For example, iron supplements are available in a slow-release form that is gentler on the stomach. To relieve stomach cramps at home, it can be helpful to apply a heating pad or a cold pack to the stomach for twenty to thirty minutes at a time. Some individuals have found chamomile tea, ginger, and licorice to be beneficial in relieving stomach cramps as well. Patients should always let their doctor know if they have very sharp stomach cramps that do not go away, as these may be signs of a more serious medical condition.

Gas And Bloating

Gas and bloating develop most often from the use of fiber and protein supplements, especially those in powdered form. Iron pills and multivitamins could also cause gas and bloating, and some patients experience abdominal bloating after taking calcium supplements. Both vitamin C and vitamin E are known to contribute to flatulence, especially when consumed in larger doses. To reduce gas and bloating from supplements, individuals might want to take chewable supplements instead of those that must be swallowed whole. For example, chewable calcium supplements are associated with less bloating than other formulations. If possible, individuals who take multivitamins might want to consider switching to prenatal vitamins. While they contain many of the same minerals and nutrients as multivitamins, prenatal vitamins are generally easier for the large intestine to absorb, and this typically results in less bloating. Patients who experience gas or bloating after taking a supplement should consider discontinuing it. In particular, individuals who notice bloating after supplement use need to speak with a doctor. Occasionally, bloating could be a sign of more serious gastrointestinal problems, including cancer.
