This has been really helpful for me. A while back I had gotten the nutrition report from Xcode and it really helped me understand certain aspects of my diet. Fast forward about two years and I am sluggish, irritable, tired, etc. I discussed it with my doctor and they ran some bloodwork. Turns out I'm deficient in some vitamins and needed to supplement. I went back and reread my xcode report and they are the exact same vitamins that the report told me I would need to supplement. Turns out I don't metabolize them as efficiently and need some additional help to meet my requirements. Overall, it was a really great experience and I look forward to ordering more of the reports.
