What Does A Nutrition Test Check?

This nutrition blood test will check vitamin and mineral levels and identify any vitamin deficiencies, so you can make the necessary adjustments to your diet or compensate with supplements where required.

You will receive your body's scientific levels for key vitamins such as vitamin D, active B12, iron and magnesium which are important in supporting the body’s immune system and also help to promote good sleep. This test will also check your levels of good and bad cholesterol helping you to ensure you have the right balance. You will also gain insight into your body's level of inflammation, high levels of which can be caused by poor diet.

The blood sample for this test can be collected at-home using our finger-prick kit. Your results will be reviewed by one of our UK registered doctors and made available on our market leading biomarker dashboard within 2 working days of receipt. Here you can track changes over time and gain information, tips and advice on each micronutrient so you know what changes you need to make to your diet to improve.

Vitamin Deficiency In the UK

We carried out a study to understand the level of vitamin deficiency in the UK and found that vitamin deficiencies can affect anyone at any age. Everyone in the UK is at risk of vitamin D deficiency, whereas vegans and vegetarians are at greater risk of vitamin B12 deficiency.

Most people can improve their nutritional intake through diet apart from vitamin D where the NHS advise a daily supplement during winter months. As mentioned, vegans and vegetarians could also use supplements for vitamins such as B12.

Understanding your normal nutritional levels will help you understand how to improve your diet and identify any areas you may be lacking.

“Usually a varied diet will provide all the essential vitamins and minerals for health. However, in practice there may be challenges in achieving this type of diet, whether for medical reasons, exercise performance, availability, or personal preference. Testing vitamin and mineral levels through a blood test will inform if there are areas of nutrition that could be addressed where possible, or whether supplementation might be required. In addition, measuring cholesterol, alongside inflammatory markers such as hs-CRP can indicate potential risk of cardiovascular disease and appropriate lifestyle measures given.”

Frequently Asked Questions

Why Is Good Nutrition Important?

We all know that a healthy, balanced diet helps us stay healthy. A good diet containing the vitamin and minerals our bodies need help reduce the risk of diseases such as heart disease, diabetes, stroke, and osteoporosis. It can also help reduce high blood pressure and high cholesterol.

That is why our Nutricheck test measures key vitamins and minerals as well as cholesterol levels and inflammation.

Overall, a balanced diet will provide the vitamins and minerals our bodies needs to help fight off illness as well as improving energy levels.

Do I Need To Take Supplements?

In short, no, most of the vitamins and minerals the body needs are gained through a healthy, balanced diet rich in carbohydrates, a variety of fruit and vegetables, beans and pulses, and good quality sources of protein. You may need to take vitamin D supplements in winter if your levels are low.

You can find out more in our blog on supplements.

What Is A Normal Cholesterol Level?

In the UK, the NHS recommends a total cholesterol level (that’s HDL and LDL combined) of 5mmol/L or less. For those at higher risk of heart disease the NHS recommends a level of 4mmol/L or less.

What Does HDL and LDL Mean?

HDL stands for High-Density Lipoproteins and is known as the ‘good’ cholesterol as it carries cholesterol back to your liver and your liver removes the cholesterol from your body. LDL stands for Low-Density Lipoproteins (bad fat) and it is this that can build up on your artery walls. Our nutritional blood test checks for both HDL and LDL and gives you these individual results as well as total cholesterol.

What our customers say

Really fast and reliable results.So easy to use! Have used them3 times now and will continueto use this company, amazing.


The service was great from beginning to end. The test kit arrived quickly and was easy to use, the instructions were clear and simple to follow and my results were available sooner than I expected. Thanks everyone!


This should be the most common thing people do.
Great company, easy to read results. Well worth it. The cost is an investment


This was a really simple and quick process. I ordered the test kit, it arrived 2 days later. I did my blood test a few days later and put it straight in the post. My results were with me 3 days later. Brilliant. The dashboard is very well presented and gave me a clear view of each marker. I’m not happy with all the results, but that’s not Forth with Life’s fault. That’s down to my own body!

Mrs Heidi Tyler

As a working mum, I often find myself training ‘tired’ as the demands of day-to-day life take their toll.  Forth has enabled me to gain a valuable insight into what is happening ‘under the surface’, so I  can adapt my training and lifestyle.

Kate Allan

The kindest customer service I have ever experienced. Would definitely recommend to anyone looking for these products.

Thank You so much for your prompt responses and helping me with my order.

Much appreciated.

Mrs Mahendran

As a former Olympic cyclist I always wanted to look after my health. This has never changed to this day but become a lot easier via Forth, it’s the only way to really understand your own body. 

Brian Smith

Fast easy service putting my mind at rest quickly. Sent off sample on Monday, got results back Tuesday afternoon.


Any questions I had, I emailed to the email contact and I was answered within hours. I was really impressed with the level of service and manner of response. I believe the product is very good quality and plan to utilize more of the products in the future. The process is very simple and reliable!


Really excellent service - we bought two 'vitality' tests after reading about Forth With Life in Natural Health magazine. The packs came quickly, the phlebotomy appointment at home was convenient and professional and the results were quick and insightful- I recommend without reservation to anyone wishing to gain a comprehensive understanding of biomarkers indicative of their health and wellness!

Kate W

I'd put off getting regular blood tests before because of the long-winded process of a GP visit. Forth has changed all that. The process is very quick and very easy, with thorough, well-explained results delivered to your inbox within days.

Alice Hector

First time using a service like this looked at reviews previously before purchasing, happy to see the five stars reviews are reflective of the service. The kit arrived the next day after ordering I waited till the Monday to do the sample sent it off Monday AM and had the results back Tuesday PM. Wow what a quick service! Follow the tips about doing the blood sample and you shouldn’t have any issues, I found I only needed one lancet and the blood flowed freely after a hot shower and running my hands under warm water. I will definitely be using this service again as I got some surprising results which I’d like to see improve.


I suffer from a hereditary condition which causes my body to store too much iron.  My biggest issue before using Forth was getting an appointment with my GP.  Now using Forth I can track my iron quickly and easily and take action before levels start to affect my health

Mark Threfall, 29

Efficient, great communication and information. Very fast, next day turnaround. Very, very pleased. Highly recommended and best value I have found.


An excellent service, I got fast replies to my enquires and immediate practical solutions. I needed my results quickly after being unable to get samples on my first attempt and Forth found a resolution for me and assisted at each stage. Really great communication from individuals who have the knowledge and ability to sort things out. Wouldn't go anywhere else.


Very fast service, a fair cost, comprehensive results and an unexpectedly lengthy comment from a Dr about the findings.

I'll definitely be ordering again on a regular basis to keep an eye on things.

James S

Forthwithlife are just so helpful - professional and extremely easy to deal with. I would highly recommend these guys and would literally never look anywhere Else. Superb company.


Quick delivery and clear instructions - I sent the samples off on Thursday and received the results on Saturday. The information on each statistic was clear, and the recommendations helpful. Will definitely be following up in half a year!


I enlisted the help of Forth to help me get to the bottom of my current health concerns. The test was really easy to and my results were available within day. Using Forth has helped me take the action needed to get my hormones back on track.

Holly Rush, 39

Taking the test is simple just make sure you follow all the instructions so you follow the correct procedures. The customer service is second to none and the results are easy to understand and follow.

Matthew Bottrill

Wasn’t feeling quite right and believed I may be chronically stressed. Took the baseline plus option which is a wider range of tests and this confirmed by expectations and also highlighted two further issues which I’ve raised with my GP. Well worth the piece of mind.
