Diet & Nutrition DNA Test

About the Diet & Nutrition DNA Test

The Diet and Nutrition DNA Test is an at home genetic test that looks at how your body is set up to handle food, nutrients and energy. Rather than following general advice, you get a written report built around your own genetic results, covering areas such as lactose and caffeine handling, fat and glucose metabolism, appetite signals and your need for vitamins such as D, B12, folate and A.

How it works

Small differences in your DNA, known as variants, can influence how efficiently your body absorbs and processes certain nutrients. The laboratory reads a defined set of these variants from your sample and groups them into the reports listed above. Each report explains what the variant is associated with in published research, what your own result was, and what that may mean day to day for your meals, snacking patterns and supplement choices.

How to use it

You order the kit online and it arrives by post. Collect your sample with the cheek swab provided, which takes a couple of minutes and does not involve a blood sample. Register the kit with the code in the box, return it in the prepaid envelope, and your report is released to your secure account once the laboratory has processed it. The report can be downloaded and shared with a dietitian, personal trainer or GP if you want to discuss it.

What the test measures

Lactose intolerance, fat and glucose metabolism, caffeine metabolism, alcohol response, folate (B9), vitamin B12, vitamin D and vitamin A. It also covers your predisposed sugar conversion and innate diet routines: feeling full and hunger response, energy metabolism, food pleasure response and appetite, binge eating and snacking behaviour, sugar sensitivity, proinsulin conversion rate, fasting blood glucose, glucose regulation and glucose uptake sensitivity. Sample collection is by cheek swab.

Who it is for

The test is for adults who want a more personal starting point for their eating habits, whether the aim is steadier energy, a better structured diet or simply understanding why some foods suit you more than others. It is not suitable for anyone under 18, and it is not designed for people looking for a diagnosis.

Safety and when to get advice

A DNA test of this kind gives information about tendencies, not certainties, and it does not diagnose any condition or replace advice from a healthcare professional. Genetics are only one part of the picture alongside sleep, activity, stress and what is actually on your plate. If you have a diagnosed condition, are pregnant or breastfeeding, or take regular medicines, talk to a clinician before you make significant changes to your diet or start a supplement.

Common questions

How long do results take?
Turnaround begins once the laboratory receives your registered sample. You are notified by email when the report is ready in your account.

Do I need to fast before the swab?
No fasting is needed. Avoid eating, drinking, smoking or brushing your teeth for about 30 minutes before you swab so the sample is clean.

Will my result change over time?
Your DNA does not change, so the genetic result stays the same. How you act on it can change as your goals or circumstances do.
