Vitamin B6

fP -B6-Vit

€ 59.40

We need B vitamins for the body’s energy production and the well-being of cells, skin, bones, muscles, organs, and the nervous system. Because B vitamins are water-soluble and are excreted in urine, we must continuously get them from food or nutritional supplements.

Vitamin B6 (pyridoxal phosphate) is found in pork, chicken, fish, legumes, wheat germs, and bananas. Vitamin B6 is necessary for the nervous and immune systems, and it takes part in the metabolism of amino acids (building blocks of proteins) and the formation of haemoglobin.

When is a good time to measure vitamin B6 levels?

The test is recommended when nutrition is not in order or the following common signs of vitamin B6 deficiency occur:

  • Rash
  • Skin infection
  • Tongue infection
  • Soreness in the corners of the mouth
  • Numbness, stinging, or burning sensation in the arms or legs
  • Anaemia
  • Fatigue
  • Insomnia
  • Mental changes
What does a vitamin B6 test measure?

The test is used for investigating vitamin B6 deficiencies. A deficiency can emerge in connection with malnutrition, alcohol addiction, or malabsorption. Coeliac disease is an example of such malabsorption.

Normally, the result is: 

Reference values:

  • 20-120 nmol/l

Results below the reference range may be an indication of vitamin B deficiency, but they do not tell us the reason, that is, whether the intake of vitamin B is not sufficient or the body is unable to absorb vitamin B. People often have other vitamin deficiencies in connection with vitamin B deficiency.

The reference values of this examination have changed 11.10.2021. You will find your own result's reference values from My LOUNA in touch with the graph. Read more about defining reference values.

Please contact your physician or other healthcare professional if you suspect an illness or need help interpreting the results.

Vitamin B toxicity, or excessive vitamin B levels, is rarely seen. This condition is possible in connection with excessive use of supplements that contain B vitamins.

Vitamin B6 deficiency can occur in connection with the following situations:

  • Chronic high alcohol consumption
  • Insufficient vitamin B content in the diet
  • Malabsorption in the gastrointestinal tract
  • Gastrointestinal disorders (gastric bypass surgery)
  • Pregnant women with a limited diet
  • Elderly people
  • Smokers
  • A high-protein diet
  • Deficiency in another vitamin or mineral prevents the use of vitamin B
  • Haemoglobin that transports oxygen to tissues (1552 Hb, 2474 B-PVK, 3696 B-TVK)
  • Coeliac disease tests. Coeliac disease is gut damage caused by gluten (1666 S -IgA, 1885 S -tTGAbA)
