Could your tiredness be a B12 deficiency?

So, where does B-12 come from? Why are some of us lacking this vital vitamin and what does B-12 deficiency look like?

With our busy and stressful lives, it’s not surprising that we often feel tired. But could there be more to it than lifestyle?

It’s estimated that around 6% of the UK population is deficient in Vitamin B12. And, with more people turning to a plant-based diet, that number could well be on the rise.

How does this link to feeling tired? Vitamin B-12 is essential for your health. Playing a critical role in the production of red blood cells and in helping your nervous system to function properly, this water-soluble vitamin is extremely important for regulating much of how your body functions day-to-day. If you’re deficient in B-12, you can experience a whole host of symptoms, from tiredness to memory problems.

What is vitamin B-12 and why do we need it?

Vitamin B-12 is needed to maintain normal brain function. It’s also involved in the production of red blood cells and helps to create and regulate our DNA. Every single cell in your body relies on vitamin B-12 and its key role releasing energy by helping your body absorb folic acid.

Your body produces millions of red blood cells every minute, but they can’t multiply properly without vitamin B-12. If your levels are too low, the production of red blood cells reduces which, in turn, can result in anaemia.

What can happen if you’re deficient in B-12?

A deficiency in B-12, or folate, can cause a wide range of problems. One of the most prevalent symptoms is low energy and fatigue.

You can also experience:

  • Mouth ulcers

  • Muscle weakness

  • Pins and needles

  • Problems with memory

  • Psychological problems, which may include depression

  • Sore, red tongue

What causes low levels of B-12?

It’s possible to develop B-12 deficiency if your diet is lacking in foods which are rich in the vitamin, such as milk, eggs, and meat. This can be a concern for those who follow a vegetarian or vegan diet.

However, you can also be at risk of B-12 deficiency simply if you are older, if you are pregnant or breastfeeding, or if your body can’t properly absorb the vitamin from your diet.

Some medications, such as proton pump inhibitors (PPIs) can also interfere with your body’s ability to absorb B-12.
