Vitamin B12 is a vital Vitamin to support DNA synthesis, haemoglobin production, & nerve function. So, never ignore its importance and test your Vitamin B12 level optimally with BetterYou's NEW Vitamin B12 Test Kit.

If you feel tired, low on energy or your memory is not as sharp as it used to be, you may need to check your vitamin B12 levels. Vitamin B12 may benefit your body in an impressive way, such as by boosting your energy, improving your memory and helping prevent heart disease.

Vitamin B12, also known as cobalamin, is a crucial B vitamin that your body needs but cannot produce. Vital for the production of red blood cells, B12 supports the reduction of tiredness and fatigue and normal psychological function. 

Vitamin B-12 deficiency carries a serious risk of permanent nerve and brain damage.Therefore its deficiency should not be ignored. Many times people may have minor symptoms which they are unable to identify. But if you have one or more of the following symptoms, you should get tested for Vitamin B12 levels immediately.

  • Depression
  • Confusion and Memory Problems
  • Loss of appetite and Constipation
  • Fatigue and Weight Loss
  • Neurological Changes
  • In infants, it causes unusual movements and reflex problems


Product size Single-use 
Biomarkers tested  Active B12 

How does the test work?

This test checks your active B12 levels as this is considered the more accurate way to measure your body’s access to available vitamin B12 and the best early indicator of a deficiency.

Your results will be made available through your online dashboard, and a member of the BetterYou team will follow up with your bespoke supplementation plan within 2 working days.

Importance of checking your B12 Levels:

As we all are aware of deficiency or overload of anything can be harmful. Same goes for Vitamin B12 as well. Our active vitamin B12 test enables you to quickly identify the current B12 levels available for your body to use rather than your total B12 level. It will give you a clear insight into any risk of abnormal B12 levels.

Low B-12 levels can lead to:

  • permanent nerve cell damage
  • Deteriorating cognitive ability
  • Damaged brain function and memory loss issues
  • Megaloblastic anaemia and complaints of weakness and fatigue.

People who are obese or eat a lot of meat also tend to have higher-than-normal levels. High levels of vitamin B-12 can lead to:

  • Liver disease
  • Certain type of leukaemia
  • Diabetes

By knowing your results and getting our bespoke supplementation plan, you can make the necessary lifestyle modifications to ensure your levels remain optimal. It also helps you track your levels over time using our online portal that can contribute to regular monitoring.

Who needs it?

The test is suitable for everyone over 18 years of age. We suggest, taking the Vitamin B12 test at regular intervals to track the level in the body. Also, if you are concerned about not getting enough vitamin B12 from your daily food intake, consider taking the test to understand how much you need additionally. But there are groups of people who may be more susceptible to its deficiency and should strongly consider getting tested. These include:

  • Those with absorption issues
  • Vegan and Vegetarians
  • Pernicious anaemia sufferers
  • Pregnant and breastfeeding mothers
  • Athletes

Intelligent Choices of Health Supplements
Most of us don’t know the benefits of each element present in our body. Many times, the same elements which must be present naturally in our body, lack in amount, and we face inevitable consequences.

The BetterYou products focused upon increasing the absorption by the bloodstream and reducing gut processing. The oral sprays of BetterYou are simply sprayed on the inner cheek and s absorbed by the body faster than other oral pills or tablets.

Product FAQs

Question 1

Is there any difference between your various tests?

Answer :

Yes, the analysis method differs. Our vitamin D tests differ from our Iron and B12 tests due to the collection method and how you receive your results. Ultimately, they each provide you with a detailed picture of your levels but use different analysis methods.



Question 2

How will my data be stored?

Answer :

Do not worry; we understand the importance of data security when dealing with sensitive data such as biometric testing. Your results will be securely processed and stored on secure servers.

If you take a vitamin D test, your results will be communicated via email but if you take an Iron or B12 test, your results will be available via a secure online portal.

By purchasing and completing the tests,to share your data between BetterYou and our testing partners.



Question 3

What lab will process my sample?

Answer :

Our laboratories partner are UK based, accredited and meet regulatory standards. They are some of the largest private labs in the country but also work directly with the NHS.



Question 4

How often should I take the blood test?

Answer :

We would recommend testing at different times of the year to establish your year-round levels. We would suggest a maximum of 4 times per year, every 3-4 months would be fine.



Question 5

Can I get this test done for free by my GP?

Answer :

Blood tests can be carried out by your GP that often take a long time to complete, and you rarely get detailed results. By using one of our tests, you get a bespoke supplementation plan as soon as your results are available and it is easy to track your results over time. But if you are at all concerned with your results, you can take them to your GP for further analysis.



Question 6

Do I need to stop supplementing before testing?

Answer :

It is totally up to you if you want to stop supplementing before taking a test. If you are taking the supplement, by taking a test you will establish if you need to up or reduce your dosage but, if you decide to stop supplementation before testing, you will get a better idea of your baseline levels from diet alone.

If you do wish to find your baseline dietary level, we recommend a washout period of 2 weeks (Iron and B12) and 4-6 weeks (Vitamin D).

Always consult your GP or healthcare professional before making a change to your supplementation plan.



Question 7

Are the kits easy to use?

Answer :

Our at-home kits are incredibly easy to complete. They allow you to quickly and easily take your sample without the need for a professional or visit a GP surgery/clinic at the comfort of your home.



Question 8

Why should I choose BetterYou at-home health checks?

Answer :

By using a BetterYou at-home health check you get to see an accurate insight into your levels of a specific nutrient. Not only this, but we also provide you with a detailed supplementation plan included within the price to help you maintain or elevate your levels for optimal health.

We will also provide you with a complimentary oral spray to help you kick-start your journey to optimal health, all included in a single one-off price which is affordable and convenient.



Question 9

Who is Forth?

Answer :

Forth is one of our chosen biomarker testing partner. They are a leading UK-based private blood test provider. With a team of expert biochemists and medical doctors, they use UKAS approved laboratories to analyse your sample on our behalf.
