Vitamin D is a fat-soluble vitamin that helps to absorb the minerals calcium and phosphorous, playing a vital role in forming and maintaining strong bones and teeth, regulating normal immune system function, maintaining heart and lung health and combating depression.

Vitamin B12 is one of the eight B vitamins. It is a water-soluble vitamin. Vitamin B12 is responsible for neurological function, producing DNA, maintaining a healthy nervous system and generating red blood cells which carry oxygen around the body. It is an essential nutrient in pregnancy.

The Essential Vitamin Test measures both Vitamin D and B12, offering a fully comprehensive picture of your vitality.

You should monitor your vitamin levels as deficiencies may rule out underlying health conditions or explain symptoms such as exhaustion, brain fog, and nutritional issues.

You should take the Essential Vitamin test if:

  • You want to improve your overall health
  • You are suffering from chronic fatigue
  • You are following a plant-based diet
  • You are planning on becoming pregnant
  • You are over the age of 50
  • You suffer from Crohn's disease
