This Morning: Guest reveals symptoms of vitamin B12 deficiency
Take folic acid, for example, which isn't reserved for women trying to conceive or those who are pregnant. Without sufficient folate (the natural form of vitamin B9 found in foods), then folate deficiency anaemia occurs. The NHS says a deficiency of B9 can lead to a "wide range of problems", such as tiredness and a lack of energy.

Additional symptoms may include pins and needles, a sore and red tongue, and mouth ulcers.
The deficiency can also lead to problems with memory, understanding and judgement.
It's vital for a folate deficiency to be treated as soon as possible because it leads to "irreversible" issues.
While the deficiency can be easily treated by taking folic acid supplements, if you take the supplement every day, it can mask another underlying health condition.
The NHS warns: "Folic acid treatment can sometimes improve your symptoms so much that it masks an underlying vitamin B12 deficiency.
"If a vitamin B12 deficiency isn't detected and treated, it could affect your nervous system."
The NHS adds: "The longer the condition goes untreated, the higher the chance of permanent damage."
The NHS advises: "Before you start taking folic acid, your GP will check your vitamin B12 levels to make sure they're normal."
One of the most common causes of a vitamin B12 deficiency in the UK is due to a condition called pernicious anaemia.
The autoimmune condition affects cells in the stomach, which causes problems with the absorption of nutrients from food.
Foods rich in vitamin B12:
- Meat
- Fish
- Dairy.
What causes a folate deficiency?
The NHS explains: "Folate dissolves in water, which means your body is unable to store it for long periods of time.
"This means you need folate in your daily diet to ensure your body has sufficient stores of the vitamin."
Good sources of folate include:
- Broccoli
- Brussels sprouts
- Asparagus
- Peas
- Chickpeas
- Brown rice.
"If you don't regularly eat these types of foods, you may develop a folate deficiency," the NHS says.

Coeliac disease could also be another reason, aside from diet, that leads to a folate deficiency.
If you suspect you have a deficiency, a simple blood test can determine if you are or not.
First speak to your doctor about any concerns you may have and, together, you can decide on the next best steps.
