A groundbreaking 2024 randomized, placebo-controlled crossover study published in Nutrition and Dietary Supplements demonstrated that a multi-digestive enzyme and herbal dietary supplement significantly reduced post-meal abdominal distension in healthy adults. Participants experienced up to 68% less abdominal distension 90 minutes after taking the enzyme blend compared to placebo, highlighting the supplement’s ability to alleviate bloating effectively.

This reduction in distension is crucial because bloating is not just a subjective feeling—it often involves measurable physical expansion of the abdomen, which can be uncomfortable and socially distressing. The study’s supplement combined 18 digestive enzymes, including proteases, lactase, lipase, amylases, cellulases, plus herbal ingredients like ginger root, fennel seed, and peppermint leaf, which together support digestion and soothe the gastrointestinal tract.
Certain carbohydrates, such as those found in beans, lentils, and cruciferous vegetables, contain complex sugars (galacto-oligosaccharides) that humans cannot digest naturally. These sugars ferment in the colon, producing gas and bloating.
Â
Digestive enzymes like alpha-galactosidase specifically target these carbohydrates, breaking them down before they reach the colon. Clinical trials confirm that alpha-galactosidase supplementation significantly reduces gas and bloating after high-fiber meals. Products like Beano leverage this enzyme to provide relief from gas-related symptoms.
Lactose intolerance is widespread, affecting approximately 36% of Americans and up to 68% of the global population. It occurs when the body produces insufficient lactase to break down lactose in dairy products, leading to gas, bloating, and diarrhea.
Â
Supplemental lactase enzymes help by breaking down lactose into glucose and galactose, which the body can absorb easily. A randomized controlled trial with lactose-intolerant individuals showed that lactase supplementation reduced symptoms by 55%, making it an essential enzyme for dairy-sensitive individuals.
Lipase and protease enzymes are critical for digesting fats and proteins, respectively. Insufficient lipase can cause post-meal fullness, heaviness, and nutrient malabsorption, especially after high-fat meals. Similarly, protease deficiency can lead to undigested proteins causing gut irritation and bloating.
Â
Supplementation with these enzymes improves the breakdown of fats and proteins, reducing digestive discomfort and enhancing nutrient uptake. Research also indicates that plant-derived proteases like bromelain and papain have anti-inflammatory properties, further aiding digestive health.
