Check your active vitamin B12 levels with our home finger prick blood test kit analysed at one of our UKAS accredited UK labs.

This B12 blood test kit measures the active form of B12 which is the most accurate means of measuring your level of vitamin B12 (as opposed to total B12). Active B12 is the best early indicator of B12 deficiency.  

Vitamin B12 (along with folate) plays an essential role in the formation of red blood cells and also has a key role in nerve health. The human body doesn’t produce Vitamin B12, so it has to be absorbed through diet. Low levels of this essential vitamin can leave you feeling tired and weak while prolonged deficiency can lead to anaemia.

This test enables you to check your active B12 levels quickly and easily.  Simply send your sample direct to our lab and accurate results will be available within 48hrs on our secure online health dashboard. 

Why check Vitamin B12 ?

  • You want to check levels to ensure your diet is ok
  • You want to check if you need to supplment or are over-supplementing
  • You are suffering from low energy levels
  • You want to guard against anaemia

Benefits of vitamin B12 testing

By taking our home vitamin B12 blood test, you can get fast and accurate insights into your vitamin B12 levels.

If you’re experiencing a lack of energy or feelings of weakness, this test could identify whether a B12 deficiency is at the root of those issues.

By the same token, those who are simply being proactive about assessing their health and guarding against any future deficiency or anaemia will benefit from this accurate insight into existing levels.

Given that the body does not produce vitamin B12, our intake has to come from diet, a blood test to check your levels is an excellent indicator as to whether improvements might be needed to your diet in order to prevent a deficiency.

Our check includes a quick and simple finger prick test carried out at home. Your results will be made available in a simple, easy to read dashboard, where you can also track your levels over time and gain information, tips and advice on how to improve.

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.

Sarah

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.

Gary

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

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!

Courtenay

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

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

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.

JeannieBrady

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

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!

Odradek

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

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!

Debbie

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.

Jamie

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

Armstrong

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

Emma

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.

Sam

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

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

Justin

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

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

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

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.

Frequent Questions

Depending on the test you select, blood samples are collected by finger prick or phlebotomy. A blood collection kit will be sent to your address. This kit contains all you need to collect the blood sample and includes a guide to collection as well as a pre-paid return envelope for your sample.
Phlebotomy means that the blood sample is drawn direct from the vein. This type of sample needs to be done by a qualified healthcare professional. We have developed a national network of clinics and home-visit phlebotomists who conduct this service on our behalf.
Essentially yes, anyone can collect the sample required easily and quickly providing they follow the instructions given. Finger prick kits contain a small lancet which pierces the skin. The finger is then massaged and the resulting droplets of blood are used to fill the small collection tubes. It is imperative that you fill the tubes to the indicated line or analysis may fail.
For convenience we recommend you collect your sample first thing in the morning. This is compulsory for some tests which have biomarkers which fluctuate depending on the time of day or with the intake of food. Please ensure you follow the instruction for your particular test carefully.
It is absolutely essential that the blood sample is posted to our laboratory within the pre-paid envelop on the day the sample is taken. The tubes contain chemicals which help to delay the clotting of blood. Any delays in the sample reaching the laboratory may mean analysis will fail or inaccurate results.
Test results which fall outside the normal range are reviewed by one of our registered healthcare professionals who will provide you with advice alongside your results. You can also download your results from your dashboard and take them to discuss directly with your own GP who holds a record of your full medical history.
If you have any concerns about your health or your results you should discuss these directly with your GP. The tests Forth offers are not a replacement to seeing your own GP. Our tests are designed to give you a deeper insight into your own health so you can improve your wellbeing, levels of fitness and sports performance. They are not intended for clinical diagnosis. You can download a copy of your results to share with healthcare professionals from your account dashboard.
Blood tests conducted through a GP surgery often take a long time to complete and you are rarely given the detailed results. You may also not be given access to certain tests. Forth gives you direct access to a wide range of wellbeing tests to help you check and improve your health status and optimise your performance
As red blood cells regenerate approximately every 120 days, we recommend re-testing every 3-4 months to track your improvement.
All our laboratories are accredited and meet UK regulatory standards. Our main laboratory partner is one of the largest private laboratories in the UK and provides pathology services to the NHS as well as private healthcare hospitals and clinics.
