Why take this test?
What better way to check whether you are getting important nutrients you need from your diet than with a simple nutrition check you can do at home? Most balanced diets should provide us with all the vitamins and minerals our bodies need without the need for supplementing or testing, but even with the best intentions, not everyone eats as well as they could all the time. You may even choose to restrict your diet whether for animal welfare, sustainability, health and performance issues, or maybe there are certain foods that just don't agree with you. Whatever your reason, our nutrition check can help you understand whether you need to include more vitamins and minerals in your diet, or whether you might benefit from taking a supplement.
This profile also includes other markers that could be influenced by your diet; a full cholesterol profile with a breakdown of LDL (bad) and HDL (good) cholesterol as well as a marker for inflammation (CRP-hs).
We send you an easy-to-use kit to collect your blood sample.

Our tests are not a substitute for seeing your doctor, especially if you are suffering symptoms. Our doctors will interpret your results based on the information you have provided, but will not diagnose, consult or provide any treatment. You will be advised to see your doctor for any necessary follow-up action.
Triglycerides are a type of fat (lipid) that circulate in the blood. After you eat, the body converts excess calories into triglycerides which are then transported to cells to be stored as fat. Your body releases triglycerides to be used for energy.
Raised triglycerides are thought to be a risk factor for peripheral vascular disease (affecting the blood vessels which supply your arms and legs as well as organs below the stomach) as well as microvascular disease, affecting the tiny blood vessels around the heart.
Cholesterol is an essential body fat (lipid). It is necessary for building cell membranes and for producing a number of essential hormones. Cholesterol is manufactured in the liver and also comes from the food we eat. Elevated cholesterol is a risk factor for heart disease - the recommended level is below 5 mmol/L.
Cholesterol however is made up of both good (HDL) and bad (LDL) cholesterol so it is important to investigate a raised total cholesterol result to determine the cause. High levels of HDL cholesterol can cause a raised total cholesterol result but may actually be protective against heart disease.
HDL cholesterol (high density lipoprotein) removes cholesterol from the bloodstream and transports it to the liver where it is broken down and removed from the body in bile. HDL cholesterol is commonly known as "good cholesterol".
Raised levels are believed to be protective against heart disease, while low levels are associated with increased risk of a heart attack.
LDL cholesterol (low density lipoprotein) carries cholesterol, triglycerides and other fats to various tissues throughout the body. Too much LDL cholesterol, commonly called "bad cholesterol", can cause fatty deposits to accumulate on artery walls, potentially leading to atherosclerosis and heart disease.
Non-HDL cholesterol is calculated by subtracting your HDL cholesterol result from your total cholesterol. It therefore includes all the non-protective and potentially harmful cholesterol in your blood, not just the LDL cholesterol. As such, it is considered to be a better marker for cardiovascular risk than total cholesterol and LDL cholesterol. The recommended level of non-HDL cholesterol is below 4 mmol/L.
HDL cholesterol (high density lipoprotein) removes cholesterol from the bloodstream and transports it to the liver where it is broken down and removed from the body in bile. HDL cholesterol is commonly known as "good cholesterol" as raised levels are believed to be protective against heart disease, while low levels are associated with increased risk of a heart attack.
The ratio of total cholesterol to HDL is more indicative than a total cholesterol result alone to find out whether your cholesterol levels are healthy. This ratio should be as low as possible.
Ferritin is a protein which stores iron in your cells for your body to use later. Measuring ferritin levels gives us a good indication of the amount of iron stored in your body.
Low levels of ferritin can indicate anaemia which can be caused by excessive or chronic bleeding, poor absorption of iron or too little iron in the diet.
Raised ferritin levels can indicate iron overload syndrome (haemochromatosis) or any kind of liver damage. It is also a marker of infection and inflammation.
C-Reactive Protein (CRP) is an inflammation marker used to assess whether there is inflammation in the body - it does not identify where the inflammation is located. High Sensitivity CRP (CRP-hs) is a test which is used to detect low-level inflammation which is thought to damage blood vessels which can lead to a heart attack or stroke.
Raised levels are a risk factor for cardio-vascular disease.
Magnesium is an important mineral needed for proper muscle, nerve, and enzyme function. It helps the body make and use energy and aids the movement of electrolytes such as potassium and sodium into and out of cells.
The kidneys remove any excess magnesium from the body so developing raised magnesium levels (hypermagnesemia) is rare. However, those with kidney problems and those supplementing high amounts of magnesium may be at risk of developing hypermagnesemia.
A low magnesium level can be caused by poor nutrition and a high intake of alcohol. Magnesium is found in a variety of foods including nuts, leafy green vegetables, legumes and whole grains.
Zinc is necessary for immune function, wound healing, taste, smell and is essential for cell division and growth. Zinc also removes toxic metals such as copper, lead and mercury from the brain.
Even though zinc is an essential requirement for a healthy body, too much zinc can be harmful. Care is needed when taking zinc supplements as it is possible to overdose on zinc. A raised zinc result may be due to over supplementing.
A low result may be caused by a lack of zinc in your diet. Zinc can be found in red meat, poultry, pulses, seeds and nuts.
Vitamin B12 is important for production of red blood cells which carry oxygen around the body - low levels can cause anaemia with associated symptoms of lack of energy and fatigue. It is also important in metabolism and for the nervous system and prolonged lack of vitamin B12 may cause nerve damage. Vitamin B12 is almost entirely found in meat and animal food products.
Around 70% of vitamin B12 is bound to carrier proteins in your blood. This test measures the level of unbound or active B12 which is available for your cells.
A common reason for elevated B12 is over-supplementation. Raised levels of vitamin B12 may indicate a blood or liver disorder.
Low levels are seen in people with pernicious anaemia, an autoimmune disease which prevents the absorption of vitamin B12, or anyone who suffers from absorption problems such as the elderly, people with inflammatory bowel conditions and alcoholics. Vegetarians and vegans can also be low in vitamin B12, especially if they don't consume foods which have been fortified with vitamin B12 or take B12 supplements.
Folate is a water soluble vitamin which is needed by the body in your diet every day. It plays a role in DNA replication and protection, it's important for the production of red blood cells as well as in the prevention of neural tube defects in babies.
Low levels can indicate anaemia and can be implicated in raised homocysteine levels.
Although called a vitamin, vitamin D is actually a hormone which is activated by sunshine on your skin. Vitamin D is essential for bone strength as it helps your intestines absorb calcium. However, it is thought that vitamin D also plays an important role in immune function, as well as in many chronic diseases and mental health.
Many people in the UK do not produce enough Vitamin D, especially in the winter months with fewer daylight hours. It is now recommended that you get 10 - 15 minutes of unprotected sun exposure every day to ensure you are producing enough vitamin D. In winter months, if your levels are found to be low, you may wish to take a supplement.
