Protein Shakes and IBS: Ingredient Density Can Overload Sensitive Guts
Protein shakes can be useful but are a frequent IBS trigger when formulas include hard-to-tolerate proteins, sweeteners, or thickening agents. Formulation and dose are key.
Why Shakes Can Trigger Symptoms
- Some protein sources are less tolerated in IBS-sensitive phases
- Sweeteners and gums may worsen bloating or urgency
- Fast intake of large liquid calories can intensify symptoms
How to Test
Remove commercial shakes for 2-3 weeks, then test one simplified shake formula at a small serving. Track symptoms over 24-72 hours and compare protein types in separate trials.
