Erg enthousiast!
De nieuwsgierigheid naar mijn eigen DNA en wat het over mij onthult, leidde me naar 4GOLD. De resultaten hebben me toch verbluft. De analyse biedt diepgaande inzicht over mijn algemene gezondheid, voeding, sportieve prestaties, etc. Wat deze ervaring nog opmerkelijker maakte, was de uitstekende communicatie van 4GOLD. Ze hielden me regelmatig op de hoogte van de voortgang van mijn analyse en stonden altijd klaar om mijn vragen te beantwoorden. Een ander pluspunt is dat de 4GOLD-app voortdurend wordt bijgewerkt met nieuwe informatie en functies, wat de waarde ervan alleen maar verhoogt. Ik ben ervan overtuigd dat iedereen zou moeten overwegen om een DNA-analyse te laten uitvoeren. Het is een buitengewone manier om jezelf beter te begrijpen en stappen te zetten naar een verbeterde gezondheid en prestaties.

DNA must-have for all people
DNA analyse gedaan voor mezelf en mijn vrouw. Zeker aanrader voor iedereen die bewust wil omgaan met zijn lichaam / zorgen voor zijn lichaam. Wij zijn beide geen zo'n intensieve sporters, dus dit was niet de reden. We zijn veel meer te weten gekomen van ons lichaam en bepaalde zaken waar we zeker gaan opletten naar toekomst toe.

Great and valuable insights in your body - also very clear explanation and tips
I only had to wait 3 and a half weeks to get my results back. And now I know where I need to support my body. Apparently my vitamin D intake and conversion is disrupted and I can use some gut support. The app is very user friendly and they have video's with explanation on alot of important topics. Also special thanks to Nikolaas for taking his time (way longer than the scheduled 30min) to elaborate on the findings in my dna and share his knowledge with me and give me tips on supplementation, diet, etc. I highly recommend to schedule the video call with your questions.

DNA-analyse
Zeer nuttige info. Een aanrader!

Zeer tevreden na 1 jaar toepassen
Ik heb deze DNA-test laten doen, omdat ik op één week meer dan 12 uur sport. (Triatlon) Voor ik de test liet doen had ik steeds veel last van een opgeblazen gevoel en voelde ik mij vaak heel moe, ook herstelde ik niet altijd even goed na een training. Uit de testen bleek dat ik lactose intolerant ben, waardoor ik mijn levensstijl helemaal heb omgegooid. Uit geen enkele andere test bij de dokter kwam lactose intolerantie eruit. Uiteindelijk na een jaar alles uit te testen dat overeenkomt met met DNA, ben ik super tevreden met de resultaten. Ik heb nauwelijks last van een opgeblazen gevoel en ik herstel na elke training super goed. Ik voel mij vitaal ook veel beter en mijn sportprestaties zijn er hard op vooruit gegaan. Het DNA profiel wordt ook nog steeds aangepast en bijgewerkt met leuke nieuwe snufjes en info. Ik kan deze DNA-test aan iedereen aanraden die om de één of andere reden nog twijfelt om het wel of niet te doen. Gewoon doen!

Onthullende inzichten voor optimale prestaties
De DNA-analyse van 4GOLD heeft mijn sportieve prestaties en levenskwaliteit aanzienlijk verbeterd. De diepgaande kennis en persoonlijke aanbevelingen op basis van mijn genetische profiel hebben me geholpen mijn training, voeding en herstel te optimaliseren. De toegankelijkheid van deze waardevolle informatie zou voor IEDEREEN beschikbaar moeten zijn, aangezien het een ware revolutie betekent voor het bereiken van persoonlijk succes. Dit is de toekomst voor zoveel sectoren.

Great body data analysis.
It really is a great body data analysis. It took me 4 days to read and understand everything. I found out that I have a perfectly developed VO2max, I have good endurance, I have mixed muscle fibers. It responds well to caffeine, and bcaa or creatine is not good for me, if I have lactose intolerance and a problem with vitamin D3, it will show us all the problems with the skin, missing vitamins and minerals, how healthy we are, the condition of our intestines. I just miss testing for supplements like beta alanine or citrulline. And the application advises what supplements are good for us and what is not only the 4Gold company. And they don't give replacements, which I really don't like. 4Gold should "play" fair play with their customers. I know good quality 4Gold. But you have to give the recipient a choice. And don't force one type (brand) of a product.
4GOLD
Dear Robert, Thank you for your valuable feedback on our 4GOLD DNA analysis. We appreciate you sharing your thoughts and experiences with us. We're glad to hear that you found our DNA analysis valuable and gained useful insights. Regarding your desire for more specific information on supplements like beta-alanine or citrulline, we want to clarify that our analysis is based on scientific data, and we can only provide insights when there is a clear causal relationship between a genetic variant and the response to a specific substance. As of now, we may not have insights on every product in the market, but we continuously update our DNA app. We believe that as research progresses, we will be able to provide more comprehensive insights in the near future. Thank you again for your feedback, and if you have any further questions or concerns, please don't hesitate to reach out to us. Best regards, The 4GOLD Team

It's incredible to see the positive impact on my overall well-being!
Over the past few years, my primary personal struggle has been maintaining a consistent energy level. I've sought help from numerous doctors, specialists, coaches—you name it—but it provided me with no answers whatsoever. In my quest, I found some relief by eliminating certain foods that seemed to trigger sensitivity. However, after a few checkups, I found myself restricted to a diet of salads and chicken just to avoid the dreaded brain fog. Desperate for a breakthrough and trying to desperately avoid days controlled by brain fog, Brent finally recommended that I take their 4GOLD DNA test, assuring me that their approach was unparalleled. So why not? And finally, I feel like I know what's going on with my body and how to take steps towards solving it. Alongside gaining a lot of different insights, I now feel amazing, thanks to the lifestyle changes prompted by the DNA test. Notably, my heart rate variability (HRV) has skyrocketed since implementing these changes. It's incredible to see the positive impact on my overall well-being. I want to share some of these insights, hoping that other people will also take the same step and better understand their bodies: ☕ Coffee - It turns out that my body metabolizes caffeine quickly, resulting in a shorter-lived impact. Injury-Prone Alert: my DNA reveals that I may be more prone to injuries. So I need to focus on proper warm-up routines and explore lower-impact activities like cycling. The Gluten Story: I've always wondered if I had a sensitivity to gluten. While my DNA doesn't confirm it outright, it indicates that I carry the gene associated with gluten sensitivity. This knowledge empowers me to make informed choices regarding gluten consumption and prioritize my digestive well-being. Battling "Leaky Gut": Ah, the elusive "leaky gut" syndrome, which has left me feeling puzzled. Understanding my DNA has shed light on the situation. It seems that my gut barrier is more permeable, making it easier for undigested particles to enter my bloodstream, leading to inflammation and the dreaded brain fog. While it's a challenge to address, I now know the importance of supporting my gut health and digestion to combat these symptoms. ☀ The Vitamin D Dilemma: With my body absorbing less and converting it to the active form at a lower rate, it's no wonder I've struggled with energy. Discovering my genetic disposition toward lactose intolerance will definitely change my eating habits even more! I can't emphasize enough how transformative this experience has been for me. The 4GOLD DNA test has not only provided valuable insights but has also improved my overall well-being. I highly recommend it to anyone looking to take control of their health.

DNA analysis
Heel blij met deze DNA analyse, geeft je echt meer inzicht in hoe je lichaam omgaat met bepaalde voedingssupplementen, voeding op zich, de invloed oo je sportprestaties,enz….. heel erg interessant!

a treasure of info
Great, it gives a treasure of info about how your body reacts to certain foods/drinks and a lot of other insights!

Heel tevreden
Ik was al meer dan een jaar zoekende om op gewicht te blijven en van een opgeblazen gevoel in de middag af te komen. Tijdens het fietsen werd dit ook steeds meer een last. Sinds de uitslag van de DNA kit heb ik meer zicht op **** mijn lichaam werkt en slechts met een paar kleine wijzigingen in voeding ga ik terug naar mijn oude gewicht en is het opgeblazen gevoel weg. Zeer tevreden dus. Daarnaast ook meer zicht in mijn lijf en gezondheid in het algemeen + handvatten voor tijdens het sporten. Aanrader voor iedereen die twijfelt! Geld meer dan waard.

DNA Analysis
The process is fine, however I dont know how t initiate or maybe 4gold shoudl initiate the conference call to walkthrough the analysis. The DNA is very valuable IF you know how to adopt thisin your daily nutrition and or workouts.
4GOLD
Hi Bob! Thanks for your review! You can simply request a call at dna@4gold.eu, we would be happy to help you better understand the results.

flabbergasted !
When I went thru the results I recognised myself in each step on the way .. I’m so happy that I can adjust my training and dieet. The first signs are hopeful! I would greatly recommend this product and dashboard for people who love data and are looking for the last 20% of improvement.

Very happy with the DNA analysis
I am very happy that I did the DNA analysis with 4 Gold. Since I got my results few months ago, I adjusted my diet and supplements, which helped me to loose weight and at the same time have more energy than before. My sport performance is also getting better and better. It is also a great way of learning more things about yourself. The talk with Nikolaas was very good and all the explanations were clear and helpful. I also really like the fact that we get a life time access to the DNA dashboard which gets regularly updated, now also with interesting tools. Lastly, a big thank you to customer support of 4Gold who are always on top of things and ready to help.
Wat een inzichten!
De combinatie van de DNA test + de consultatie (inclusief) is zeer waardevol! Als ondernemer is het voor mij belangrijk om continu energie te hebben en te pieken om de organisatie te doen groeien. Weten waar je zwakke punten liggen of net waar je veel energie van haalt is een gigantische meerwaarde. Het geeft mij de motivatie om nog meer een gezonde lifestyle na te streven waar genieten van alles wat lekker is kan, maar waar je weet hoe je lichaam tot het maximale (gezonde) kan pushen. De kennis en customer care die het 4GOLD team te bieden heeft maakt de hele ervaring nog eens zeer aangenaam, geloofwaardig en professioneel. Aanrader!!!

top ervaring
duidelijke en kwaliteitsvolle info
No, it's really easy and painless to do. You just collect some saliva with a cotton swab on the inside of your cheek.
For the best results, it is highly recommended not to eat, drink (except water), smoke or chew gum during 30 minutes before collecting saliva.
When the DNA kit arrives just read the instructions carefully before taking your sample.
The box in which the kit was sent shows a QR code and a link to dna.4gold.eu . Scan the QR-code with your smartphone or surf to the website. Fill in the requested details to register your kit. After registration, you will be redirected to the instructions to successfully take your saliva sample. After you have successfully completed the registration and collection of the sample, you need to return the DNA kit.
Send us an email at DNA@4gold.eu 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.
At this time, we can also analyse genetic data files from 23andme. You can find more information on this product page.
No, your DNA is fixed. Only gene expression can change over time. That is why the information in your raw genetic data file is still usable after many years. Keep it at hand if updates are available, because every day new scientific research emerges that provides new insights into genetics and nutrigenetics.
Your raw DNA datafile will be sent to you by email. Once we receive a response that you have received the files correctly, all files of your DNA will be removed. That’ s why it is important that you save the files properly. You can then upload this file in our DNA dashboard at dna.4gold.eu and view your results.
You have full control over your data. So you decide who gets access to it.
At 4Gold, only our specialists have access to your raw data file and DNA reports to check and validate your results.
Yes! We have made a special dashboard for paramedics (doctors, physiotherapists, dietitians, trainers,...). They can create a free account and use the dashboard to securely acces the genetic data of patients (completely GDPR compliant). This way, they can discuss results with them or they can personalize certain services - for example, setting up a diet, interpreting a blood analysis or drawing up a training plan. Would you like to give your doctor, dietitian, trainer access to your data or are you a paramedic who would like to work with us or has questions about this? Please contact us at dna@4gold.eu.
After countless years of research, our research team has developed software that solves the main problem of most commercial DNA reports. They do not take into account the interaction between genetic variants. This may seem like a minor problem, but genetic variants can either reinforce or counteract each other. We have developed complicated algorithms to take the interaction between genetic variants into account.
