When your pancreas doesn't make enough digestive juices, your body can't properly absorb vitamins A, D, E, and K from your food—so you might end up low on all of them at once.

Assessment Explanation
The claim describes a well-established physiological mechanism: pancreatic enzymes (especially lipase) are essential for breaking down dietary fats into fatty acids and monoglycerides, which then form micelles with bile salts for absorption. Without these enzymes, micelle formation fails, leading to malabsorption of fat-soluble vitamins. This mechanism is consistently documented in clinical literature for conditions like chronic pancreatitis, cystic fibrosis, and post-pancreatectomy states. The use of 'causes' is justified because the pathway is direct, biologically plausible, and reproducible across human studies.
More Accurate Statement
“Exocrine pancreatic insufficiency causes concurrent deficiencies in fat-soluble vitamins A, D, E, and K through impaired micelle formation and subsequent malabsorption in the small intestine.”

Exocrine Pancreatic Insufficiency and Malnutrition in Chronic Pancreatitis: Identification, Treatment, and Consequences
This study found that people with a poorly functioning pancreas often lack important vitamins (A, D, and E) that need fat to be absorbed — which makes sense because the pancreas helps break down fat. So yes, the claim is supported.
