Ferritin, iron studies and the fatigue question — putting it in its own thread so it does not get lost in the check-in.
Evidence question. I would rather have an honest "we do not know" than a confident answer.
The claim I keep seeing is stated with enormous confidence and I cannot find a single primary source for it anywhere.
I am asking because two people I trust have told me opposite things and both of them cited the same study.
No hurry on this one. It is a reading question rather than a decision.
