Vitamin B12 is a nutrient that helps keep the body’s nerve and blood cells healthy and helps make DNA – the genetic material in all cells. As the National Institutes of Health (NIH) explains, vitamin B12 also helps prevent a type of anaemia called megaloblastic anemia that makes people tired and weak. Due to the vital role vitamin B12 plays in the body, becoming deficient in the nutrient can impact the body in a number of insidious ways.
There are several warning signs associated with the mouth, and the most conspicuous signs can be seen on your tongue.
You may experience an inflamed tongue, which tends to change colour and shape, and may become 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.
In addition, an inflamed tongue can change the way you eat and speak.
It is imperative to see a GP if you’re experiencing symptoms of vitamin B12 deficiency.
As the NHS points out, these conditions can often be diagnosed based on your symptoms and the results of a blood test.
It is also important to get any symptoms checked as soon possible because problems caused by the condition can be irreversible if left untreated.
“The longer the condition goes untreated, the higher the chance of permanent damage,” warned the NHS.
Vitamin B12 can be found in the following foods:
- Beef liver and clams, which are the best sources of vitamin B12.
- Fish, meat, poultry, eggs, milk, and other dairy products, which also contain vitamin B12.
- Some breakfast cereals, nutritional yeasts and other food products that are fortified with vitamin B12. To find out if vitamin B12 has been added to a food product, check the product labels.
Vitamin B12 can also be taken in supplement form, which is usually recommended if the underlying cause is due to your diet.
People who find it difficult to get enough vitamin B12 in their diets, such as those following a vegan diet, may need vitamin B12 tablets for life.
Although it’s less common, people with vitamin B12 deficiency caused by a prolonged poor diet may be advised to stop taking the tablets once their vitamin B12 levels have returned to normal and their diet has improved, explained the NHS.
