Can Normal Vitamin B12 Levels Still Affect Brain Health: Vitamin B12 has long been considered an essential nutrient for the body and brain. Doctors usually check through blood test whether its quantity in the body is correct or not. If the report is above the prescribed limit, then the person is considered completely normal. But now a new research has raised questions on this thinking. Scientists say that despite B12 level being normal in many elderly people, problems related to brain and nerves may start.

Why is there a problem even though B12 level is normal?

This research has been done by scientists of California University, the results of which have been published in a medical journal. The study found that despite having normal B12 levels in some elderly people, effects on brain function and nervous system were visible. Vitamin B12 plays an important role in making red blood cells in the body, keeping nerves healthy and making DNA. Its deficiency can cause problems like anemia, weakness, numbness in hands and legs, weak memory and loss of balance. Until now, doctors have focused mainly on cases of severe deficiency, but new research says problems may start much earlier.

Shocking revelation in research

The research team studied 231 healthy elderly people with an average age of about 71 years. None of them had the problem of dementia or mild mental weakness. The scientist examined not only the total B12 level but also the active B12. This is the form that the body is actually able to use. The interesting thing was that the B12 level of most people was normal according to medical standards. Despite this, thinking speed and visual processing were found to be slow in people who had low active B12. Research also revealed that the nerves of his brain were responding slowly to signals.

Flaws are being revealed in the investigation

The scientist noticed another important thing in the brain scan. People who had less active B12 had more white matter lesions in their brains. White matter works to transmit messages between different parts of the brain. Damage to these parts is linked to stroke, dementia and mental decline. Neurologist experts said that this study shows that current medical standards are not able to fully capture the early brain and neurological problems of B12. According to him, in many people the effects on the nerves and brain can begin even before obvious symptoms are visible.

What is the effect of Vitamin B12?

Scientists say that with increasing age the body’s ability to absorb B12 decreases. Some medications, digestive problems, and a completely vegetarian diet can also increase the risk of B12 deficiency. However, researchers have clarified that this study does not directly prove that less active B12 is the cause of mental decline. But it definitely shows that despite normal reports, changes can start in the brain.
