Micronutrient tests

Screenshot 2019-11-19 at 09.07.25Both a deficiency and excess in micronutrients can lead to increased oxidative stress chronic inflammation, an imbalance in the immunity and an increase risk of chronic diseases including heart disease, arthritis, dementia and cancer [1]. Micronutrients include vitamins, essential minerals, fatty acids and phytochemicals, particularly the important polyphenols [2].I

Even with a healthy diet we cannot be certain that we have the correct balance of nutrients. Taking mineral and vitamin supplements may do more harm than good as, notwithstanding the expense, they may over correct a baseline normal level and give false confidence that they have sufficient or the correct ingredients to correct a deficiency. The most reliable way to ensure you have the correct amounts of vital nutrients in your diet is to measure the body’s levels. A measure of these nutrients will empower you with the knowledge to be able to modify your diet, or take specific supplements, which will give you the best possible chance of avoiding or fighting chronic disease or improving sport performance.

This test was designed by Professor Robert Thomas, an experienced UK Oncologist, a professor of biological and sports science with a research interest in the field of lifestyle, nutrition and wellbeing.  In collaboration with a long established nutritional laboratory, it measures the essential micro nutrients which have been implicated in the chronic disease pathway, including cancer…. read more

It is recommended for people who want to progress to next level of understanding about their nutritional status.  It will provides clear and specific guidance for foods to avoid and which to eat more of in order to restore nutritional harmony. It is possible to have an imbalance of micronutrients for years before the strain on the body presents itself. Sportsmen and women have them regularly to aid optimal nutrition programmes to help them recover from training and improve performance and protect their joints and muscles. People recovering or experiencing chronic diseases including cancer will get reassurance or corrective guidance to ensure they ar din the strongest position to fight their disease

Combining the important tests into one profile makes this the most cost effective way of measuring over fifty micronutrients.

How to order the micronutrient tests?

Ordering online has allowed us to reduce administrative cost which means we have managed to pass this saving onto you. The process is very straightforward and if there are any issues you can email us to ask any questions at health-education@clara.co.uk

Step one
Click on the pay now link, below, to take you to the paypal site so you can securely pay with credit or debit card. You will receive a conformation email once payment has been acknowledged.

Step two
The laboratory will then send you a kit containing tubes for blood samples, packaging and an addressed envelope. It would be better to stop taking any dietary supplements you take for at least 48 hours before the blood test. It would be best have the test done earlier in the week so it doesn’t reach the lab late on a Friday.

Step three
You then have to go to your local blood taking facility to take the blood sample (usually your GP’s practice or a phlebotomy room in your local hospital – some phlebotomy centres may charge a small fee for this).  In the unlikely event that you are have trouble getting someone to take the blood, you are very welcome to go directly to the lab in central London ( the address will be on the packaging). After the blood has been taken, label the pots, immediately put them into the packaging and envelope provided and post as soon as possible.

Step four (your report);
Professor Thomas will review your individual results, write your report and provide specific dietary and lifestyle advice relevant to your individual results.
