Your body doesn't make enough vitamin D not because you're not getting enough sun or food, but because your pancreas or liver isn't working right — so the deficiency is a sign of a deeper problem, not the root cause.

Exocrine Pancreatic Insufficiency and Malnutrition in Chronic Pancreatitis: Identification, Treatment, and Consequences

Cross-Sectional Study

Human

2018 Sep

This study found that people with a poorly functioning pancreas often have low vitamin D — not because they don’t get enough sun or food, but because their pancreas can’t help absorb it. So low vitamin D is a sign of pancreas trouble, not the cause of it.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

People with a long-term pancreas problem that stops it from digesting food properly often lack key vitamins like D, A, and E—more than half are low in vitamin D, which can happen because their body can’t absorb fats well.

People with long-term pancreas inflammation often lack vitamin D — about 6 in 10 of them do — but even those with very damaged pancreases aren’t more likely to be deficient than those with milder damage, so how bad the pancreas looks on a scan doesn’t tell you if someone needs more vitamin D.

If your pancreas isn't making enough digestive juices, taking vitamin D pills won't help because your body can't absorb the vitamin properly—it needs fat to soak it up, and your pancreas isn't helping with that.
