What Actually Works for Bloating?

Bloating supplements promise flat stomachs. Most don't address the actual cause. Here's what research supports, and what you should investigate first.

TL;DR

Best evidence: Digestive enzymes (for specific deficiencies), Peppermint oil (IBS), Probiotics (specific strains). Moderate evidence: Ginger, Fennel. Doesn't work: Most "debloat" supplements, apple cider vinegar.

⚠️

Elimination diet

Lactose, FODMAPs, gluten sensitivities cause bloating

2-4 weeks

Check eating habits
Self-assessment

Days

Real Talk

Bloating has a cause. Food intolerance, eating too fast, swallowing air, SIBO, IBS. Supplements treat symptoms, not causes. Figure out WHY you bloat before throwing pills at it. An elimination diet is worth more than any supplement.

What Else Actually Helps

  • Low-FODMAP diet. gold standard for IBS bloating
  • Eat slowly. swallowing air causes bloating
  • Avoid carbonated drinks. obvious but ignored
  • Regular movement. helps motility
  • Stress management. gut-brain connection is real

The Bottom Line

Find the cause first. Peppermint oil works for IBS. Lactase if lactose intolerant. Specific probiotics can help. Skip the "debloat" supplements with random ingredients.
