Scientists find a big cause of hidden inflammation in the body

A new study has found an important link between vitamin B12 and long-lasting inflammation in the body.

This could change how we think about staying healthy. Chronic inflammation plays a big role in serious diseases like heart problems, diabetes, and brain issues.

Vitamin B12 is already known to help keep nerves and the brain healthy. It also helps make red blood cells. But now, researchers have discovered that vitamin B12 might also help reduce inflammation.

Inflammation is the body’s way of reacting to injuries or infections. That’s useful in the short term, but if it lasts too long, it can harm the body and lead to disease.

The study was published in the Journal of the Science of Food and Agriculture. It looked closely at two markers in the blood that show inflammation: interleukin-6 (IL-6) and C-reactive protein (CRP). These markers rise when the body is inflamed.

Previous research suggested vitamin B12 could reduce inflammation, but this new study gives stronger evidence. The scientists used data from a large study in Spain called the PREDIMED trial. That trial focused on how the Mediterranean diet affects heart health.

In this new study, researchers checked the blood of people in the trial and found something clear: people with higher vitamin B12 levels had lower IL-6 and CRP levels. In other words, they had less inflammation.

This matters because it means keeping your vitamin B12 at a healthy level might help reduce inflammation and lower the risk of many chronic diseases.

Even though the study didn’t only include people with very low B12, it still showed that having enough B12 is important for everyone.

When people don’t have enough of this vitamin, they may feel tired or weak, and their nerves or brain might not work as well. This new study suggests that these problems might also be linked to inflammation inside the body.

Scientists now want to learn more. They plan to study more people and look at differences between men and women. They’re also interested in how health problems like infections, obesity, and irritable bowel syndrome (IBS) are linked to B12 and inflammation.

Another question is why vitamin B12 levels drop as people get older. One reason could be that the body becomes less able to absorb it from food. The researchers also want to look at how B12 works differently in animals compared to people.

These future studies could help older adults avoid vitamin B12 deficiency and lower their risk of inflammation-related health problems.

In short, this research shows that vitamin B12 is not only good for nerves and blood—it might also protect against harmful inflammation. Watching your vitamin B12 levels could be an easy and powerful way to stay healthy and avoid serious illness.
