About flexible subscriptions

How does a subscription work?

When you purchase this test subscription plan, we will automatically send you another test kit in a few months. Don't worry - you have full control over when this will be, and you can change/cancel it anytime.

When you first purchase this test, you can choose your subscription options in the checkout. We do this, because we recommend taking multiple tests over time to track how your biomarkers change. You'll be charged per test kit (rather than monthly, for example).

Why subscribe to multiple tests?

One test will show you what areas you need to focus on, continued testing will help you learn how your training, diet and lifestyle is impacting your health.

How often should I test?

We recommend a follow up test 3 months after your first test, followed by a test every 6 months depending on your results, but its up to you!

Can I change what's tested in future tests?

Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.

Blood sample collection options

You can choose your preferred collection method when you checkout

Finger prick kit (FREE)

You can do this test at home without the need for a doctor. We'll send you everything you need to collect your sample and post it back to us. And it's all included in the cost. We've put together a video that covers the process, making it easy to check and track your health from home.

Home nurse appointment (+£60)

We'll arrange for a medical professional to visit your home and collect your sample. This is great if you're unsure on how it all works or have trouble collecting a sample. No need to book a doctor's appointment or visit a clinic, we'll send you everything you need to collect a sample and post it back to our labs.

Visit a partner clinic (+£45)

Once you've ordered your test, look out for an email from our phlebotomy partners containing information and a link to book your appointment. We'll send you everything the clinic will need to complete the sample and post it back to our labs.

Organise a nurse myself (FREE)

If none of the above options work for you, you can arrange your own medical professional to collect your sample. There is no additional charge for this. Once you've ordered your test, we'll send you everything you and your chosen medical professional will need to collect a sample and post it back to our labs.

What does a vitamin B12 test check?

A B12 vitamin deficiency can make you feel extremely tired and lacking in energy. Taking this Active B12 home blood test is the best way to identify how much vitamin B12 is available for your body to use. It’s different from a total B12 test that measures the total amount of B12 stored in the body.

We’ve made our vitamin B12 blood test easy to do from the comfort of your home. The kit contains everything needed to collect a small amount of blood and post it back to our labs for analysis.

What causes vitamin B12 deficiency?

Vitamin B12 deficiency can result from factors such as a bad diet, malabsorption due to conditions like pernicious anaemia or gastrointestinal disorders, certain medications that interfere with absorption, or insufficient production of intrinsic factors needed for B12 absorption in the stomach.

Vitamin B12 Blood Test, recommended by our doctors

"B12 is crucial for making red and white blood cells, repairing cells, and synthesising new DNA. It can't be produced in the body and must be supplied by the diet. Foods rich in vitamin B12 are usually animal based, so this test is particularly useful if you're following a vegetarian or vegan diet. We focus on the active form of B12 giving greater insight into your functional levels."

The nurse will give you the blood sample to return to us using the pre-paid envelope provided.
