Did you know?
Increasing magnesium levels can help reduce the risk of stroke, heart failure and diabetes.
How can a magnesium blood test help you?
This test checks the magnesium levels in your blood serum. 99% of the magnesium in your body is found in your bones, muscles and tissue, with the rest in your blood serum.
Checking your levels can help uncover the causes of symptoms related to high or low magnesium levels.
Symptoms of a magnesium deficiency include;
- Muscle weakness
- Fatigue
- Irregular heartbeat
- Nausea and vomiting
Symptoms related to high levels of magnesium in your blood include:
- Diarrhoea
- Nausea
- Stomach cramps
How to test for magnesium deficiency at home
Checking for a magnesium deficiency at home is easy with our finger prick blood test. It has everything you need to collect a small blood sample and send it back (for free) to our NHS labs for analysis.
It takes around 15 minutes to complete the test and once the sample has reached our lab, we aim to return your results within 2 working days.
You’ll be able to see your magnesium levels, as well as where they should be for your age and gender.
Benefits of magnesium
Magnesium is an essential mineral that plays an important role in over 300 reactions in the body. You should get most of the magnesium you need from your diet, but you can also get magnesium supplements.
Magnesium is needed for:
- Muscle function
- Nerve function
- Bone health
- Heart health
- Energy production
- Blood sugar control
- Digestive health
It can also be helpful for pregnant women, helping with foetal development – especially bone and nervous system development.

It’s easy to take a finger prick blood sample, but we know for some this can be a bit nerve-wracking, especially if you haven’t done it before.
So, we’ve created a how-to video to help you collect a successful sample.
But don’t worry if you don’t manage to get it right first time, just contact our customer support team at [email protected] to request a replacement kit.

Can I have someone take my blood for me?
Yes. We offer two options if you do not want to do our finger prick test. The first is a home appointment where a nurse comes to your home to take a blood sample. The second is to visit a Phlebotomy clinic near you that offers a blood sample service.
A blood sample will be taken from your vein and we will provide you with everything you need to give to the nurse to allow them to take the sample.
The nurse will give you the blood sample to return to us using the pre-paid envelope provided.
