What our
been saying

"As a working professional in the field of peak performance and a competitive athlete, I am deeply invested in how to optimize my internal systems. Taking the guess work out of what I should be doing to fuel my body through real data is an incredible tool."

"I Learned so many new things about my body and nutrition, including what foods and habits to modify based on my genes to reverse my insulin resistance. I dropped my HbA1c to normal levels after 4 months."

Michael Cook
D-Feat customer

"A very comprehensive and informative tool. I started the year on a Keto diet and learnt from my personalized report that I can get better results from a Low carb diet. Now I enjoy more carbs, which helps my mood, and I got to my target BMI."

Matt K
Control customer

"The 3TandAi personalized report helped me and my nutritionist finally discover what was causing my acne and high sugar levels (it had to do with my body's ability to process omega fats and its poor metabolism of Vitamin D). I made the recommended changes and life is better!"
