Vitamin B12 is one of the most important nutrients for the body’s overall health, but huge numbers of people might not be getting enough B12 in their daily diet. You could be at risk of a deficiency if you notice some slight changes to your tongue.
Vitamin B12 is used by the body to make new red blood cells, nerves, and DNA.
It’s also used in a number of other everyday bodily functions, but huge numbers of people may not be getting enough in their diet.
The body doesn’t naturally engineer vitamin B12 – like it does for vitamin D – which is why it’s crucial that everybody eats enough B12-rich foods.
But if you are at risk of a deficiency, you could develop some changes to your tongue.

“Unfortunately, symptoms of a vitamin B12 deficiency can take years to show up, and diagnosing it can be complex,” she wrote for medical website Healthline.
“Glossitis is a term used to describe an inflamed tongue.
“If you have glossitis, your tongue changes colour and shape, making it painful, red and swollen.
“The inflammation can also make your tongue look smooth, as all the tiny bumps on your tongue that contain your taste buds stretch out and disappear.”
But just because you develop a swollen tongue, it doesn’t necessarily mean that you have a B12 deficiency.
Glossitis could also be caused by a dry mouth, acid reflux, or even simply a reaction to eating spicy foods.
Your glossitis is more likely to be caused by a vitamin B12 deficiency if it’s accompanied by some other common mouth symptoms.
Persistent mouth ulcers, pins and needles in the tongue, or even a burning pain inside the mouth could all be caused by the condition.
