Is BPA in receipts and canned food changing vitamin D levels?

What's actually in it

Bisphenol A (BPA) is a chemical used to make hard plastics and is often found in the lining of food cans and on thermal paper receipts. It is an endocrine disruptor: a chemical that interferes with how your hormones work. While many people worry about how these chemicals affect their health, the science is still catching up on specific links to nutrients like vitamin D.

We know that children are exposed to BPA and its alternatives through everyday items like toys, as shown in a 2026 study in J Expo Sci Environ Epidemiol. This exposure is not limited to just one source, which makes it hard to track exactly how these chemicals interact with your body over time.

What the research says

While there is a lot of concern about BPA, the current body of peer-reviewed research does not confirm that it directly changes vitamin D levels in the body. Most studies focus on how vitamin D itself acts as a helper for other health markers.

For example, a 2026 study in Environ Int looked at how vitamin D levels play a role in how the body handles metals during pregnancy. This research highlights that vitamin D is important for health, but it does not provide evidence that BPA from receipts or cans is the cause of low vitamin D.

Because BPA is known to disrupt hormones, it remains a substance to avoid whenever possible. Even if it is not the direct cause of vitamin D changes, it is a chemical that does not belong in your food or on your skin.
