23 Biomarkers
Additional biomarkers can be added by personalising this test.
Biomarkers are specific compounds we can detect in your blood sample that reflect different things about your health. Your test will tell you your levels for each of the above biomarkers, and whether they are in a normal range.
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).
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.
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!
Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.

Blood sample collection options
WHEN TO TAKE THE TEST?
Collect your blood sample within 3 hours of waking.
If you’re wanting a more comprehensive analysis to help identify the cause of low energy, then this test is for you. It checks key nutrients such as vitamin D, B12, folate and ferritin along with cortisol (stress), magnesium, and hs-CRP (inflammation). To rule out conditions that could be causing your symptoms this test also checks HbA1c (pre-diabetes) along with thyroid, liver and kidney function along with immune health.
23 Biomarkers
Liver health
Liver tests, frequently known as liver function tests (LFTs), are a group of blood tests that help assess the health of your liver. These tests measure the levels of various enzymes, proteins, and substances produced or excreted by the liver. Abnormal results in these tests can indicate liver disease or dysfunction, which can significantly influence energy levels.
Vitamins
Vitamins are essential nutrients obtained from food and sunlight. They support vital functions like bone health, energy production and fighting infection. Deficiencies can lead to various health issues, including bone disorders, anaemia, low mood and fatigue.
Minerals
Minerals support bone strength, muscle function, nerve signalling, and energy production. They regulate vital processes such as blood pressure and immune responses. Key minerals like calcium, magnesium, and iron are obtained through diet and are crucial for preventing deficiencies and maintaining overall health.
Full Blood Count
A Full Blood Count (FBC) test measures various components of blood. In this test it includes red and white blood cell count together with haemoglobin. These tests helps identify conditions like anaemia, a common cause of fatigue, where the blood lacks enough healthy red blood cells to carry adequate oxygen to the body's tissues.
Haemoglobin A1c (HbA1c)
HbA1c provides an average reading of blood sugar levels over a period of 2-3 months. It is considered one of the best indicators of pre-diabetes. While HbA1c itself is not directly involved in energy production, it provides critical information about blood glucose control, which is closely linked to energy metabolism.
Kidney function
Kidney function tests assess how well the kidneys filter waste and balance fluids and electrolytes. Impaired kidney function can lead to toxin build-up, electrolyte imbalances, and anaemia, all of which can contribute to fatigue and reduced energy levels.
Thryoid Function
Thyroid hormones help to control the rate at which your body converts food into energy. Thyroid imbalance can lead to problems with weight, energy and mood.
Cortisol
Cortisol, a hormone released during stress, regulates metabolism and immune response. Chronic high cortisol levels can disrupt sleep, increase blood sugar, and deplete energy reserves, contributing to persistent fatigue.
