About
This study aims to show how digestive enzyme supplements help the body break down fats, proteins, and carbohydrates, especially after eating a high-fat, high-protein meal. Digestive enzymes are essential for nutrient absorption, but some people-such as those with certain medical conditions or high-protein diets-may not produce enough on their own. Poor digestion can lead to bloating, discomfort, and gut imbalances. This clinical trial tests a delayed-release, porcine-derived enzyme blend to see if it improves digestion and reduces symptoms like bloating and gas after eating a high-fat and high protein meal.
Full description
This study explores the potential benefits of digestive enzyme supplementation for individuals consuming high-fat, high-protein meals. Digestive enzymes play an important role in breaking down macronutrients to facilitate nutrient absorption. While the body naturally produces these enzymes, certain factors such as genetic predisposition, aging, or high dietary intake of fats and proteins can strain the digestive system, leading to incomplete digestion and gastrointestinal discomfort.
High-fat and high-protein meals require significant enzymatic activity for proper breakdown, and inadequate digestion can result in symptoms like bloating, indigestion, and changes in gut microbiota. Undigested fats and proteins in the colon can contribute to digestive discomfort, while improperly broken-down carbohydrates may lead to increased gas production and microbial imbalances. These effects can impact overall digestive efficiency, nutrient availability, and gut health.
This clinical trial investigates the efficacy of a delayed-release, porcine-derived enzyme blend containing 20,000 lipase units in improving digestion and gastrointestinal well-being. The study follows a randomized, placebo-controlled, crossover design to assess how this enzyme supplement affects macronutrient breakdown and post-meal symptoms. Researchers will evaluate both immediate effects after a single dose and longer-term benefits after seven days of supplementation, including its impact on quality of life. The findings may provide insight into whether digestive enzyme supplementation can enhance nutrient absorption and alleviate digestive discomfort in individuals consuming high-fat, high-protein diets.
