can protein shakes cause constipation
Why does protein powder cause constipation and bloating? In sensitive people, protein powders can cause constipation and/or bloating based on the type of protein and/or sugars used. If constipation is the issue, using a protein powder with fiber may help. If bloating happens it may be that you are sensitive to lactose (milk sugar), which is common in less expensive formulas. In this case using a whey protein isolate formula may help and/or add an over-the-counter lactase supplement.
