Vitamin B12 deficiency symptoms: What colour is your tongue? Surprising sign in your mouth

Vitamin B12 is a very important ingredient for the healthy running of the body. But unlike vitamin D, it’s not naturally made within the body, meaning you could be at risk of a deficiency if you aren’t eating the right foods. One of the easiest ways to reveal your risk of a B12 deficiency is to check the colour of 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, it can be difficult to even know.
