What gets tested?
14 Biomarkers
Additional biomarkers can be added by personalising this test.
What are biomarkers?
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.
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.

What this test measures
14 Biomarkers
Active B12
Active B12 measures forms of B12 which are available for direct use by the body. This vital vitamin helps to boost energy, improve mood, and enhances cognitive function. It can mainly be found in fish, dairy products and meat such as beef, which is why vegetarian and vegans are more prone to deficiency.
Vitamin D (25 OH)
Vitamin D is essential for healthy bones, immune function, muscle performance, energy, mood and reducing inflammation. It's primarily produced through sunlight exposure and only small amounts can be consumed through diet.
Corrected Calcium
Calcium is the most abundant and one of the most important minerals in the body. Calcium is vital for cell signalling, and the proper functioning of muscles, nerves, and the heart. Foods best for boosting calcium include; dairy products, leafy green vegetables, nuts and legumes.
Magnesium
Magnesium is a vital trace element essential for maintaining strong bones, regulating blood pressure, facilitating muscle contraction, and producing energy. Since the primary source of magnesium is through diet, testing your magnesium levels can identify deficiencies and help you make necessary dietary adjustments for optimal health.
Ferritin
A ferritin test measures the total level of iron stored in your body. Iron is crucial for energy production, immune function, cognitive health and muscle performance. Including iron-rich foods such as red meat, dark leafy vegetables and whole grains in your diet is essential for maintaining healthy levels.
Full Blood Count
3
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.
Red Blood Cell (RBC)
An RBC test measures the number of red blood cells in your blood. Red blood cells are an important transporter of oxygen, taking it from the lungs to cells around the body. Low RBC is often an indication of anaemia which can be due to a number or causes including nutrition deficiency.
White Blood Cell Count
White blood cells are crucial for fighting infections and are a key part of the immune response. A low WBC can increase susceptibility to viral, bacterial, and fungal infections, impacting overall health. Your diet supports WBC production through essential nutrients like protein, vitamins,, minerals omega-3s and hydration.
Haemoglobin
Haemoglobin, found in red blood cells, carries oxygen throughout the body, enabling cellular respiration and energy production. Low haemoglobin levels can indicate anaemia, leading to reduced energy. By improving your haemoglobin you can improve your organ and tissue functions and increase your overall energy levels.
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. Healthy HbA1c levels can be maintained by managing carbohydrate intake, increasing fiber, balancing protein and healthy fats, limiting sugar and moderating alcohol consumption.
Cholesterol (lipid panel)
5
A cholesterol or lipid panel test measures various cholesterol components to assess cardiovascular disease risk. Too much saturated fats in your diet raises LDL cholesterol levels increasing the risk of heart disease and stroke.
Total Cholesterol
Total cholesterol is a value made up of the different cholesterol components - HDL, LDL and triglycerides. It’s not just your total cholesterol that’s important, as it’s possible to have a healthy total cholesterol number but an unhealthy balance of the different types of cholesterol.
LDL
LDL (low-density lipoprotein) is known as bad cholesterol because it can transport more cholesterol around the body than needed, leading to a build up on the walls of arteries. The higher the levels of LDL the higher the risk of developing heart disease.
HDL
HDL (high-density lipoprotein) is known as 'good cholesterol' as it picks up excess cholesterol in your blood and transports it to your liver for removal. Healthy fats, such as those from fish, nuts, and olive oil, can increase HDL.
HDL:Cholesterol Ratio
The total cholesterol to high-density lipoprotein (HDL) ratio is used to assess the balance of cholesterol in the blood. The lower the ratio the lower the risk of developing cardiovascular disease. For women, low levels of oestradiol can raise the cholesterol ratio increasing the risk of cardiovascular disease.
Triglycerides
Triglyceride is the main form of fat found within our bodies. It is important for maintaining energy and provides the fuel for muscles to work. When you eat, excess calories which your body doesn't need are converted into triglycerides. High levels can increase the risk of heart disease.
What are vitamins and minerals?
Vitamins and minerals are essential nutrients that our bodies need to function properly. Vitamins are organic compounds that help regulate various bodily processes and support overall health. They are needed in small amounts and can be obtained from food or supplements. Minerals, on the other hand, are inorganic substances required for various physiological functions, such as building strong bones, transmitting nerve impulses, and maintaining fluid balance. They are also obtained through diet and are crucial for maintaining good health. Both vitamins and minerals play vital roles in keeping our bodies functioning optimally and preventing deficiencies and health problems.
Causes of vitamin and mineral deficiencies
Vitamin and mineral deficiencies can happen for a variety of reasons. One common cause is poor diet. If your diet is lacking in fruits, vegetables, or other nutrient-rich foods, you might miss out on important vitamins and minerals. Some health conditions, like IBS, can affect how your body absorbs nutrients. Some medications may interfere with nutrient absorption or increase nutrient excretion. Lifestyle choices, like restrictive diets or excessive alcohol consumption, can also lead to deficiencies. Some people, like pregnant women, young children, and older people, might need to pay extra attention to their diet to avoid falling short.
How to test your vitamin and mineral levels
Our vitamin deficiency test makes it easy to test your nutrient levels at home. It includes everything you need to collect a small blood sample and post it back to our labs. Our doctors will provide detailed insights into your vitamin and mineral levels and advice on how to improve your health. We recommend you collect your sample within 3 hours of waking up and before you eat.

Frequently asked questions
This is what our customers ask us most about this test. For more information, try our help centre.
Do I need to take vitamin supplements?
A healthy and balanced diet should give you all the vitamins and nutrients you need, but supplements can help to boost deficiencies or to optimise levels where you are struggling to consume a diet rich enough in vitamins. Pregnant women need more ferritin, so supplementation might be a more convenient method to manage the body’s demands. We get a lot of our vitamin D from sunlight, so it can be helpful to take vitamin D supplements during the winter to boost levels of this important vitamin in the darker months or if you struggle to get enough sunlight to ensure your Vitamin D levels are optimised.
What foods are high in vitamins?
There are lots of vitamins and minerals your body needs to function properly, from energy to hair growth. The key to staying healthy is eating a balanced diet, limiting the amount of ultra-processed foods you consume and tracking your vitamins and minerals through blood testing to ensure you are managing any vitamin levels that could be improved.
What do vitamins help with?
Vitamins and minerals keep you going and ensure the normal functions of cells – from hair growth, energy, immune system, vision and so much more.
