    Effect of lactase on symptoms and hydrogen breath levels in lactose intolerance: A crossover placebo-controlled study

    Baijal R, et al

    Published in JGH Open

    Methodology

    Randomized, placebo-controlled crossover study in lactose intolerant patients given a standard lactose load with lactase enzyme or placebo, with symptom scoring and serial hydrogen breath testing.

    Key Findings

    Oral lactase taken with a lactose challenge significantly reduced bloating, pain, flatulence and diarrhoea and lowered breath hydrogen excretion compared with placebo in lactose-intolerant adults.

    Conclusions

    Orally supplemented lactase enzyme significantly reduced the clinical symptoms and hydrogen breath excretion in patients with lactose intolerance.

    Limitations

    Acute challenge design (n=47) rather than habitual dietary use, short duration, and symptom outcomes that are self-reported.

    Supplements Studied

    Orally supplemented lactase enzyme significantly reduced the clinical symptoms and hydrogen breath excretion in patients with lactose intolerance.
