Vitamin B12 Test

Our vitamin B12 test kit measures you levels Methylmalonic Acid (MMA) from a urine sample. MMA is the most sensitive marker in detecting deficiencies or low levels.

Vitamin B12 is a common deficiency, which can cause symptoms such as fatigue, headaches and irritability. As these symptoms are non-specific, a deficiency can go undetected for a long time.

This key test gives you an overview of your B12 levels from a simple urine sample which can be done in the comfort of your own home.

What is measured?

This test measures Methylmalonic Acid (MMA) which is known as the most sensitive markers for measuring B12 levels.

Not having enough B12 means that MMA builds up instead of being converted into coenzyme A, making it detectable in your urine sample. B12 is a large essential vitamin that needs help through multiple biological stages to be utilised by the body. Even if you are consuming enough vitamin B12 as part of your diet and a test measuring active B12 or serum B12 show that you have enough vitamin B12 in your body, it is still possible that your body is not using it properly, which could causes symptoms and affecting your quality of life.

Who should test?

Everyone can test, but especially those who are:

  • Vegetarian or vegan
  • Older adults
  • Struggling with gastrointestinal issues
  • Living with diabetes
  • On PPI medication
  • Diagnosed with pernicious anaemia

Good service. Test report clear and concise. The only downside for me was the colour of the packaging – white writing on a yellow background. I found it really difficult to read. The instructions inside were also very faded ink. If you are doing this for the first time, the last thing you want to be doing is struggling to read the instructions

The test was easy to do at home and from activating the test all the way through to the report, there was clear communication. The test report was very clear and concise and written in plain English and not technical. I am now able to take measures to counteract a deficiency. Amazing service from start to finish

I found out my results were poor after taking the test and started taking Omega 3 capsules. I was plagued with migraines having 2 a week roughly and am delighted to say they have gone. Can’t recommend this product enough!
