What vitamins are essential for immune health?

The following vitamins and minerals have an important role in normal immune system function: Vitamin A B Vitamins Vitamin C Vitamin D Vitamin E Vitamin K Selenium Zinc Magnesium Folate Iron

How can I boost my immune system at home?

It is important to use a blood test to identify any problem areas that could be impacting the immune system’s ability to correctly function. If there are deficiencies in key vitamins and minerals, food supplements are readily available in health food shops, pharmacies, and supermarkets. It is also important to manage stress, as this can keep your body in a stress-response state that can impair the functionality of your immune system.

Can exercising improve my immunity?

Not many people realise that the lymphatic system (that connects our lymph nodes) has no pump. Instead, this system relies on our movement to ensure that fluid moves and drains through this system. Exercise can allow the immune system to work more effectively. Exercise can also prime the immune system with the increased flow of immune system cells and a post-exercise inflammatory response, effectively putting the body on guard duty. Regular moderate exercise can also reduce the amount of inflammation in the body, increasing your immunity.

What are the signs of a bad immune system?

The following can be signs that you immune system is not functioning as well as it could be: having colds frequently wounds taking longer to heal feeling tired all the time as your immune system tries to conserve energy upset stomach, with research showing most of your immune system is focussed in your digestive system

But don’t worry if you don’t manage to get it right first time, just contact our customer support team at help@forthsupport.co.uk to request a replacement kit.

The nurse will give you the blood sample to return to us using the pre-paid envelope provided.

What does an immune system blood test check?

If you suffer from frequent colds or illnesses, you could have a weak immune system. This test will help confirm if your immune system is functioning properly and if your diet is giving you enough key vitamins to support your immune health, such as vitamin D, B12 and iron.

Your blood sample is analysed at an NHS lab, where our expert medical team create your report and provide feedback on what your results mean.

What causes a weak immune system?

A weak immune system can be caused by several factors. Chronic stress, lack of sleep, over exercising and poor diet choices can all compromise the immune system’s effectiveness. Certain medical conditions, such as autoimmune disorders or chronic illnesses, can weaken immune responses. Lifestyle factors like smoking, excessive alcohol consumption, and a sedentary lifestyle can also contribute to immune system impairment.

"Our immune health blood test offers valuable insights into your immune system function. By measuring key markers like white blood cell count, antibody levels, and inflammatory markers, it helps assess your overall immune health. This information can aid in early detection of infections, autoimmune disorders, or immune deficiencies."

We’re changing people’s lives

I really like Forth and you probably saved my life because your lab discovered my critically low cortisol which was subsequently diagnosed as adrenal insufficiency by a hospital endocrinologist.

Maria

I find Forth professional and forward-thinking with a bigger range of tests than more traditional healthcare providers in the UK. I think it is closer to what you can get from US providers.

Richard C

I wanted to get more information about my own health instead of using the NHS who just test for a specific reason. I also wanted better historical data to view changes over time as the NHS systems aren’t very good for that.

James W

Finding out what is going on inside your body is key, especially now that the NHS is in crisis. If we can take control of our wellness (and flag up potential problems early) that has got to be a good thing.

Vannesa C

I am very satisfied with your excellent service and I have recommended you to all my friends who are also very interested in your products.
