What actually helps with bloating

Abdominal distension, fullness, and discomfort often occurring after meals, associated with excess gas production or impaired motility.

LGG Probiotic
probioticempty_stomach
Strong

LGG restores gut microbial balance, strengthens intestinal barrier tight junctions, reduces small intestinal bacterial overgrowth (SIBO), and modulates gas-producing fermentation patterns that cause bloating.

Dose: 10–20 billion_CFU

Berberine
herbwith_food
Strong

Berberine has antimicrobial activity against gas-producing bacteria, supports motility through smooth muscle regulation, reduces intestinal inflammation via NF-kB inhibition, and activates AMPK to improve gut metabolic function.

Dose: 500–1500 mg

Zinc
mineralempty_stomach
Strong

Zinc strengthens intestinal barrier integrity by upregulating tight junction proteins (occludin, ZO-1). It reduces intestinal permeability (leaky gut) which contributes to bloating, and supports digestive enzyme function including carbonic anhydrase.

Dose: 15–30 mg

Milk Thistle
herbwith_food
Strong

Stimulates bile production and flow, improving fat digestion and reducing postprandial bloating and fullness.

Dose: 200–400 mg

Strong

Carminative and antispasmodic properties reduce intestinal gas accumulation and smooth muscle spasm.

Dose: 500–1000 mg

Strong

Absorbs excess water, reduces gas production via microbiome modulation, normalizes gut transit.

Dose: 5–10 g

Strong

Amylase, protease, and lipase improve macronutrient breakdown, reduce undigested food fermentation.

Dose: 1–2 capsules

S. Boulardii
probiotic
Strong

Anti-pathogenic activity reduces harmful bacteria overgrowth, decreases antibiotic-associated GI symptoms.

Dose: 250–500 mg

Glutamine
amino_acid
Strong

Primary fuel source for enterocytes. Strengthens intestinal tight junctions, reducing permeability and bacterial translocation.

Dose: 5–15 g

Moderate

NAC supports glutathione synthesis which protects gut mucosal lining from oxidative damage. It also has mucolytic properties that help break down biofilm in SIBO, and modulates inflammatory pathways in the GI tract.

Dose: 600–1200 mg
