Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Lipase is an enzyme that catalyzes the breakdown of dietary fats into smaller molecules, facilitating their absorption in the digestive tract. Its use to support or treat poor fat metabolism is primarily justified by scientific evidence, particularly in the context of conditions where endogenous lipase production is deficient. The most notable application of supplemental lipase is in the management of exocrine pancreatic insufficiency (EPI), a condition in which the pancreas does not secrete enough digestive enzymes, including lipase, leading to fat malabsorption, steatorrhea (fatty stools), and nutritional deficiencies. Clinical guidelines recommend pancreatic enzyme replacement therapy (PERT), which includes lipase, as the standard of care for EPI arising from chronic pancreatitis, cystic fibrosis, or pancreatic surgery. Randomized controlled trials and meta-analyses have shown that PERT improves fat absorption and nutritional status in affected patients.

However, outside of these medical indications, the evidence for using lipase supplements to support "poor fat metabolism" in the general population is weaker. Routine supplementation in individuals without diagnosed enzyme insufficiency has not been shown to provide significant health benefits, as healthy individuals typically produce adequate endogenous lipase. Therefore, while there is strong scientific support for lipase use in specific digestive disorders, the evidence for broader use in otherwise healthy individuals with subjective complaints of "poor fat metabolism" is limited. The overall evidence rating is 3 out of 5, reflecting solid support in specific clinical contexts but limited justification for general use.
