>It just seems like a dangerous attitude of over-confidence to think you can mix and match supplements based on numbers from blood results.

unfortunately that seems to be the the only option we have - "Let thy be thy doctor" :) From personal experience - thanks to Epic software i was given the total printout of my visit to a doctor few months back - the doctor somehow completely skipped low RBC and other related counts in my blood results which were clearly showing anemia and actually did match my feelings of overall fatigue, especially setting up quickly upon trying to exercise, restless leg syndrome, etc. After looking at those blood numbers myself, i started B12 (B12 deficiency is one of the reasons for iron deficiency, and i have an underlying condition known to cause B12 deficiency which the doctor was actually aware too - though, nevermind, the doctors could do nothing with that condition too) and iron, and the things improved remarkably, in particular RLS is gone and i can exercise without hitting almost immediately that fatigue ceiling.

>Or do we even need supplements at all if we just ate well and had an active lifestyle? Speaking as someone who just had yogurt and a banana: "Let thy food be thy medicine and thy medicine be thy food."

you're enjoying condition which can be summed up as confirmation bias of a healthy person. It is a really great condition - i've enjoyed it myself for about the first 40 years of my life.
