Scientists in Canada have made an important discovery that could change how we understand and treat type 2 diabetes. The study, led by researchers from Université de Montréal and the Montreal Clinical Research Institute, suggests that vitamin K might play a key role in helping the body prevent or manage diabetes—a disease that affects about one in eleven people around the world.
Most people know vitamin K as the nutrient that helps blood clot properly. It’s found in leafy green vegetables like spinach and kale, and it’s essential for healing cuts and wounds. The reason it helps with clotting is due to a process called gamma-carboxylation, a kind of chemical reaction in the body that allows certain proteins to work correctly.
But over the years, scientists have noticed that vitamin K might be doing more than just helping blood clot. Several earlier studies showed that people with low levels of vitamin K were more likely to develop type 2 diabetes. However, no one understood exactly how or why this happened—until now.
The new study focused on the pancreas, the organ that helps control blood sugar. Inside the pancreas are special cells called beta cells. These cells produce insulin, the hormone that helps your body use sugar from food for energy. In people with diabetes, these beta cells either don’t produce enough insulin or the insulin doesn’t work the way it should.
What the researchers discovered was surprising. They found that beta cells in the pancreas have a lot of the tools needed for gamma-carboxylation—the same process vitamin K helps with in blood clotting. That suggested that vitamin K might also be helping beta cells in some way.
Then they made an even more exciting discovery. They found a new protein in beta cells that depends on vitamin K to function properly. The researchers named this protein ERGP. This protein plays a role in controlling calcium levels inside the beta cells. Calcium is important because it helps the cells release insulin at the right time and in the right amount.
When vitamin K is present, it activates the ERGP protein through gamma-carboxylation, helping it maintain proper calcium balance. That, in turn, helps the beta cells make and release insulin more effectively. This is a big deal because it means vitamin K could directly support the cells that are damaged or not working well in type 2 diabetes.
ERGP is the first new vitamin K-dependent protein discovered in over 15 years. This breakthrough opens the door to new research and possibly new treatments. Scientists now have a better idea of how vitamin K might help protect against diabetes, and they can explore ways to use this knowledge to help people living with the disease.
This discovery shows that vitamin K is more than just a vitamin for blood—it could be a key nutrient for keeping our pancreas healthy and our blood sugar levels stable. While more research is still needed, this study gives hope that one day we might be able to use vitamin K in new ways to prevent or treat type 2 diabetes.
For now, the findings are a strong reminder of how much we still have to learn about how vitamins affect our health and how something as simple as a nutrient could play a powerful role in fighting a major global health issue.
