Testing Policy

Definition Nutrition have been producing high-quality nutritional supplements for both general health and dedicated athletes since 2008, and all our Nutritional Supplemets are now produced in a HFL/Informed Sport registered facility, meaning the facility has gone through and passed a thorough drug screening process, giving us peace of mind.


All of our products are built on the solid foundations of published research and are continually evolving to keep up with the latest in scientific thinking. We have also taken into account the tremendous amount of customer feedback that we have had over the years to ensure that what you are using is simply the best that there is.


Definition Nutrition maintain strong links with Academic & Research Institutions, noted experts and health professionals and are continually engaged in clinical trials to make sure that we stay ahead of the competition, ensuring you have the highest standard of supplementation.

Definition Nutrition ensure that only the best ingredients are used in our supplements, so that whether you want to increase your athletic performance or boost your nutrient intake, you can be sure of the quality of our products.

Our range of products are used by Professional Athletes including Premiership Footballers, whilst we do not screen every product batch, those batches that are supplied to the Premiership and only those have gone through the HFL/Informed sport screening process and therefore do not contain and W.A.D.A listed banned substances. All Definition Nutrition products adhere to ISO9001 and as such are made in accordance with UK food and safety standards. As in any sport always remember that the onus is on the athlete to make sure that due diligence has been adhered to, we do not however batch test, as we think our proceedures are tough enough.
