Genetic variations in almost every gene determine why each person is unique. For this reason, one person is better at power sports and another at endurance sports. Your genetic variations also dictate if you recover fast or slow.

The way our bodies use all kinds of nutrients is very different too. For that reason, a diet- and supplementation strategy may work great for you but completely wrong for another athlete. Personalization is therefore a smart strategy to improve your performance. The basis for achieving this is to get to know yourself better through a DNA analysis.

A DNA analysis checks your genetic code and provides insights and advice on how to optimize your diet and supplementation regime according to your DNA. All you need is a basic saliva sample by a fast and simple cheek swab. This sample is sent to a genetic lab of a local university. The lab does the DNA extraction and their genotyping machines provide us with your raw genetic data. Then an algorithm based on an enormous amount of scientific literature and complemented by the experience of the team of scientists, translate all of this information into a report.

This report allows you to tailor your supplementation and diet to your DNA and to achieve even better performance if possible.

The 4Gold DNA analysis kits for saliva collection bear a CE mark.


This analysis tool establishes a link between an athlete’s DNA and its influence on the effect of foods on his/her performance.

Do you need extra or just less caffeine stimulation? Do you have a chance of disturbed intestinal flora? Do you naturally have a good recovery capacity? Does your body produce enough choline itself? Our DNA-analysis gives you these insights, with the results you can start to adapt your diet to your DNA and/or to supplement it according to your needs.

220.00 Tax incl.


This tool provides insights in how your body handles many macro- and micronutrients. Are you at risk for iron deficiency? Can your body break down lactose? Do you need extra vitamin C, D or omega 3? Do you need more fibre in your diet? Are you more sensitive to simple carbs (sugar)?

This report discusses which genetic variant you have for the genes involved in the metabolism of most nutrients and gives you insights in what the possible implications are for that genetic variant.

This tool is the combination of the sport and health DNA tool, and establishes a link in between an athlete’s DNA and its influence on the effect of foods on his/her performance. 

Do you need extra or just less caffeine stimulation? Do you have a chance of disturbed intestinal flora? 

And this tool provides insights in how your body handles many macro- and micronutrients.

After ordering a DNA analysis, you will receive a DNA sample kit. With this kit you can easily take a saliva sample.


  1. Register your kit via the link on the collector.
  2. Open the package and remove the collector without touching the sponge tip. Place the sponge as far back in your mouth as comfortable and rub along the lower gums in a back and forth motion. Gently rub 10 times. If possible, avoid rubbing your teeth.
  3. Gently repeat rubbing motion on the opposite side of the mouth along the lower gums for an additional 10 times.
  4. Hold the tube upright to prevent the liquid inside the tube from spilling. Unscrew the blue cap from the collection tube without touching the sponge.
  5. Turn the cap upside down, insert the sponge into the tube and close cap tightly.
  6. Invert the capped tube and shake vigorously 15 times.
  7. Afterwards you put the tube inside the box in which the DNA kit was delivered.
  8. Remove the pink tape from the adhesive strip to seal the box securely.
  9. At last you have to send the box back to the address provided on the back of it. Return shipping from Belgium is prepaid. For other countries, just take it to your local post office.

DNA extraction and processing your raw genetic data will roughly take 7/8 weeks. After this period of time you receive an email with both a personalized report and raw genetic data file.

You can store this file for future use, as this contains a lot of information on your genetic make-up. When there is an update of the analysis tool in the future, you simply run the raw data file again without ordering a new DNA kit.

4Gold does not store your genetic material or data. All files are immediately deleted after we’re sure you’ve received your report. 


How long will it take before I receive my DNA report(s)?

Depending on how busy the DNA lab is, you will receive your reports in roughly 7-8 weeks.

Can I eat before taking the DNA cheek swab?

Preferably do not eat, drink (except water), smoke or chew gum 1 hour prior to taking the cheek swab.

I forgot to register my DNA kit before sending it back. What must I do?

Send us an email at [email protected], and we will try to locate your sample. There are no guarantees that we can find your sample and link it to you with enough certainty. When not 100% sure, you will have to ask for a new DNA sample kit.

Will my DNA change over time?

No! Your DNA is fixed. Only gene expression can change over time. For this reason, the info in your raw genetic data file is still valid after many years. Keep it on hand as new scientific research comes out every day that provides new insights between your DNA data and your physiology.

Will the report tell me if I have a certain gene linked to a disease?

No, it won't. The algorithm that analyses your genetic data only looks at genes involved in the metabolism of nutrients.


What do the green, orange and red arrows mean in the DNA report?

Green means that you have two copies of the normal variant of that specific variation.

Orange means that you have one copy of the normal variant and one copy of the mutated variant or altered variant. Having still one normal copy usually translates into only slightly altered function of that gene.

 A red arrow means that you have two copies of the variant or mutation. This usually translated into a higher impact and alteration of the function of that gene. The specific impact is usually described in more detail in the report. 

I have some orange and red arrows, but my genetic indicator is (almost) green, is this normal?

Yes, this can happen. You cannot look at a single genetic variation to assess the total impact on a biochemical pathway. Sometimes different genetic variations cancel each other out, resulting in a green genetic indicator.

Will my genetic data be stored?

No, your raw genetic data, nor your DNA reports will be stored. Keep them and the email via which they were send saved on a back-upped location. With your raw genetic data file, the DNA reports can easily be re-run.
