Most Common Side Effects Of Dietary Supplements

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.
