“Knowing my genetics lets me train smarter, not harder. I've already tweaked my diet and lifestyle, and the results? I feel stronger, more energized, and my performance has been next level. And this is just the beginning!”
Jenny
"I took the 3X4 test out of curiosity, not for health issues. The results helped my practitioner treat my skin condition, alleviate perimenopause symptoms, and lose 18 pounds. Now, I use my children's blueprints as references for targeted lifestyle changes. I'm grateful for 3X4, which has inspired me to learn more about my body and its unique environmental interactions."

"I had been diagnosed with an aggressive, fast-growing form of breast cancer, but didn’t have an explanation what the cause was. Thanks to your tests’ guidance, I was able to achieve being in remission (less than 4 months after my 3X4 test results!)"

Can’t wait to see how 3X4’s genetic insights can help me make better personal health choices — and offer another layer of context to guide the individualized coaching we already do at ALTIS.
Kaz
"I did the 3X4 Genetics test - I was able to verify some of the things I had already figured out through experimentation that worked for me. And in addition to that I was able to learn a few more things that I could add to my diet and my supplementation that would actually take my fitness to the next level."
Frequently Asked Questions
Genetics make up the baseline “code” by which your body functions. The impact of every single choice you make throughout your life is influenced by your personal genetic makeup. We test over 157 genes that can affect your metabolism, inflammation, detoxification, fitness, weight, hormones, cognition, and response to your diet, and supplements. By understanding how your unique genetics impact these key processes, you can make smarter, more personalized decisions about your health. There may even be insights you never imagined (like whether that second cup of coffee is a good idea).
Our genetic test is designed to provide clear insights and recommendations about areas of health that are most important to you:
- Nutrient needs
What are your body’s unique needs and how do you respond to certain foods? How well do you tolerate fat and carbs? What’s your vitamin D need? Do you require extra antioxidants and Omega-3 fats compared to others? Should you limit gluten, salt, or caffeine?
- Proactive prevention
Is your body more prone to high blood pressure, high blood sugar, or high cholesterol? How can you support your cardiovascular system and your immune system for more resilience as you age? We also look at processes like your inflammation, detoxification, methylation, and more.
- Ideal Weight
Why does your body resist weight loss and how can you manage your weight in a healthy way that is personalized to your unique body?
- Stress strategies
How does your life stress affect your brain health, your hormones, your sleep quality, and your overall wellness? More importantly, what can you do about it?
You do not need to see a 3X4 Practitioner to receive your report, but when your genetics insights are combined with your medical history, unique lifestyle, diet preferences, and exercise choices, a full picture starts to emerge. If you are looking for a detailed action plan, our practitioner partners are ready to guide you on your health journey.
Yes, it is eligible for HSA / FSA.
How can I use my HSA/FSA debit card?
You would use it in the same way you would use a credit card when paying, simply enter the needed card info. If this does not work, simply pay for the test with your normal credit card, download the invoice/receipt and submit that for reimbursement.
Will I be able to claim retrospectively as well?
HSA: As long as the HSA was established before you bought the 3X4 test, HSA can be used to reimburse that expense years later.
FSA: You can claim retrospectively as long as it falls within the current fiscal year.
I bought my test via my practitioner – can I still claim?
Most definitely. Simply ask for an itemized invoice from your practitioner where you can see the 3X4 test listed and the amount. Submit that claim for reimbursement.
Every gene has been selected based on 2 factors: scientific validity and actionability. The genes in the 3X4 Test were selected from peer-reviewed scientific publications. To ascertain scientific validity, we ensure that there is adequate research to understand what the gene does and how the version of the gene you possess affects your body. Every gene in your report has been hand-picked because there is a documented action you can take to reduce your risk and improve your health.
