Your Nutrient Needs Are Written in Your DNA
Two people can eat the same foods and take the same supplements, yet get very different results. 3X4 reveals how your genes affect nutrient absorption and metabolism so you can focus on the interventions that actually move the needle.
Unlock Your Nutrient RecommendationsPersonalized Nutrition, Built for Your Biology
3X4 translates complex nutrigenetic data into practical actions so you can eat, supplement, and recover in alignment with your unique metabolism.
Targeted Supplement Strategy
Identify where your body may need additional support so you can prioritize high-impact nutrients instead of over-supplementing at random.
Better Absorption Decisions
Learn which nutrients your body may process less efficiently and adjust your nutrition plan to improve uptake and results.
Long-Term Preventive Advantage
Address nutrient-related gaps early to support healthy aging, immune resilience, cardiovascular function, and cognitive performance.
What Do We Test For?
The Nutrients category highlights the pathways that determine how efficiently your body uses key vitamins and fats. These insights help you prioritize the changes that offer the greatest return on health.
NUTRIENTS CATEGORY:
Vitamin B12
B12 supports energy production, red blood cell formation, and nervous system health. Your genes can influence how effectively you absorb and utilize it.
Folate
Folate plays a key role in methylation, DNA repair, and cellular health. Genetic variation can alter folate metabolism and increase your need for targeted support.
Choline
Choline is essential for brain function, liver health, and cell membrane integrity. Genetics may affect your ability to produce enough choline internally.
Vitamin C
Vitamin C supports antioxidant defense, collagen production, and immune function. Genetic factors can affect transport and recycling, shaping your ideal intake.
Vitamin D
Vitamin D influences bone, immune, hormonal, and cardiometabolic health. Your genes can impact both activation and receptor function.
Fatty Acids
Fatty acids are critical for inflammation balance, cell membranes, and brain health. Genetic insights help you optimize fat quality and omega balance.
Address Nutrient Gaps With Your DNA Insights
Your nutrient requirements are not one-size-fits-all. 3X4 helps you focus on the pathways where genetics has the greatest influence so every recommendation is more strategic and effective.
B12 and Folate Optimization
Support critical methylation and energy pathways with precise recommendations based on your genetic profile.
Brain and Liver Support
Use your choline insights to better support cognition, neurotransmitter balance, and healthy liver function.
Antioxidant and Immune Resilience
Adjust vitamin C support to strengthen antioxidant capacity and help your immune system handle daily stressors.
Vitamin D Precision
Get tailored strategies to optimize vitamin D status for stronger bones, immune modulation, and metabolic health.
Fatty Acid Balance
Refine your omega-3 and omega-6 approach to support inflammation balance, cardiovascular wellness, and brain performance.
Actionable Daily Plan
Translate your nutrient genetics into practical food, supplement, and lifestyle decisions you can apply immediately.

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.

The 3X4 Genetics test was really helpful for me! It helped me to not have injuries, so it's so important. I think it's one of the main things as a professional player and, of course, every single person. When you are healthy, and you feel good, you can do a lot of things!

With this test, I've unlocked the genetic edge to push my ultra-endurance limits, tailoring my nutrition, training, and recovery with pinpoint accuracy has been a total game-changer.

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
Yes. The Nutrients category highlights where your genetics may increase nutrient demand or reduce efficiency, helping you and your practitioner prioritize support more strategically.
We utilize a simple, painless cheek swab test that examines key areas of your genome to reveal lifestyle recommendations for weight loss based on your genetic variants.
Absolutely. Even with a healthy diet, genetics can still affect absorption and utilization. Your report helps refine an already strong routine to make it more effective for your biology.
3X4 genetic tests use advanced genomic technologies ensuring high accuracy in identifying genetic markers.
Our lab processes samples in 3-4 weeks on average, and results are delivered digitally to your online account on the same day they are completed.
