Coffee stimulates the colon through caffeine and chlorogenic acids, triggering contractions within minutes of drinking.
This effect happens in about 30% of people. It occurs with both regular and decaf, suggesting caffeine is not the only factor.
A Note From Our Team
We’re coffee enthusiasts, not doctors—so here’s our honest perspective:
The research cited above comes from peer-reviewed studies, but science evolves. What we know about coffee and health has changed dramatically over the decades, and it’ll likely continue to evolve. We update our content when significant new findings emerge.
Everyone’s body responds differently to caffeine. Some of us on the team drink 4+ cups daily with zero issues; others get jittery after one. Pay attention to how YOU feel rather than following general guidelines blindly. Your body knows better than any study.
