Vitamin Deficiency Tests

A varied and balanced diet usually provides you with enough vitamins and minerals for optimal health. But deficiencies can happen for a number of reasons. Some common causes include:

  • poor absorption of nutrients — for example, if you have coeliac or Crohn’s disease
  • a diet lacking in fruit or vegetables
  • a poorly planned vegan or vegetarian diet
  • drinking excessive amounts of alcohol
  • medications — like proton pump inhibitors (PPIs)
  • pregnancy — as your body has additional nutritional demands

So, it’s a good idea to check your vitamin and mineral levels, especially if you’re more at risk of a deficiency or have any symptoms. Feeling tired for no reason, having low energy, looking pale and always getting sick can all be signs of certain nutrient deficiencies. Not getting enough vitamins and minerals can have long-term impacts on our health.

Some examples of deficiencies:

Iron deficiency

Iron is a mineral that your body needs to make red blood cells — these carry oxygen around your body. If you don’t get enough iron you might:

  • feel weak
  • feel tired
  • feel dizzy
  • feel short of breath
  • get heart palpitations
  • get headaches

Vitamin D deficiency

Vitamin D is used by every cell in your body and is essential for your bone and muscle health, as well as supporting your immune system. If you don’t get enough vitamin D you might:

  • feel tired
  • get sick often
  • have weak bones — putting you at risk of osteoporosis long-term
  • have muscle pain
  • feel anxious or depressed

Folate (vitamin B9) deficiency

Folate is a B vitamin that’s required to make red blood cells and to make and repair your DNA. It’s sometimes called folic acid — the synthetic (man-made) version of this vitamin. If you don’t get enough folate you might:

  • feel tired
  • feel weak
  • feel short of breath
  • get heart palpitations
  • get headaches
  • feel irritability
  • have difficulty concentrating

Vitamin B12 deficiency

Vitamin B12 (cobalamin) plays a really important role in red blood cell production and helps your nervous system to function properly. If you don’t get enough vitamin B12 you might:

  • feel extremely tired
  • feel weak
  • get pins and needles
  • get mouth ulcers
  • have a swollen and sore tongue (glossitis)
  • have blurry vision
  • have difficulty remembering things
  • feel depressed
