Whey Protein Powder and IBS

Protein shakes and powders include a wide range of products, including some that are terrible for your gut and others that are fine, says Elena Ivanina, DO, an integrative gastroenterologist in New York City. But most protein shakes and powders should be avoided by people with IBS, Dr. Ivanina says.

“Protein powders,” she notes, “may include added sugars, unnecessary calories, artificial colors and flavoring, emulsifiers and thickeners, and excessive vitamins and minerals that may impact gut health and symptoms.”
