Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Enzyme blends, typically composed of digestive enzymes such as amylase, protease, and lipase, are sometimes used to address digestive symptoms like belching. The rationale is that insufficient digestive enzymes can lead to incomplete digestion of food, resulting in increased fermentation by gut bacteria, which produces gas and may contribute to belching. Several small clinical trials and observational studies have explored the efficacy of digestive enzyme supplements in relieving symptoms of indigestion, bloating, and gas, which are often associated with belching. These studies suggest that enzyme supplementation can modestly reduce gas production and improve overall digestive comfort in some individuals, particularly those with pancreatic insufficiency or functional dyspepsia. However, the quality of evidence is limited, with relatively small sample sizes and variable study designs. There is a lack of large-scale, high-quality randomized controlled trials specifically targeting belching as an isolated symptom. Overall, while the scientific rationale is plausible and initial studies are somewhat positive, more robust research is needed to firmly establish the effectiveness of enzyme blends for treating belching in the general population.
