We all have blood lab work done to gauge our internal health. Same with Function Health, except there's SO MUCH MORE info! Plus, there's vast explanations for what we're looking at, why it's important, likely causes and best practices to bring any out of healthy range back to normal. I could never remember this much from a doctors visit. And now, I have all this to review any time. Actually looking forward to my next lab work.
