    Gas Reduction

    Less intestinal gas production and flatulence.

    TL;DR

    Excess gas is usually fermentation of specific carbohydrates by gut bacteria. Identifying the trigger food beats any supplement, though targeted enzymes work well for known lactose or oligosaccharide intolerance.

    Why It Matters

    Persistent bloating and gas may indicate lactose intolerance, SIBO, coeliac disease or IBS. Sudden change in bowel habit with weight loss or bleeding needs prompt medical assessment rather than self-management.

    How to Measure

    Biomarkers

    Hydrogen and methane breath testing
    Symptom-food diary
    Coeliac serology
    Bristol stool scale

    Optimization Protocol

    Run a structured elimination and reintroduction, ideally a low-FODMAP trial with dietitian support, rather than cutting foods indefinitely. Use lactase with dairy or alpha-galactosidase with legumes when the trigger is known. Eat slowly, avoid carbonated drinks and sugar alcohols, and walk after meals.
