Ingredient
Iron
We have read Iron against nine things that were measured, from five sources. Our own to-read list holds 18 things for Iron, and nine of them are still to read.
This is a library, not advice. No recommendation, no dose, no diagnosis, no ranking. We never ask about your symptoms, and nothing here is tailored to you.

Still to read for Iron
Our to-read list holds 18 things for Iron. Nine of them have no reading here yet:

- Endurance Performance (Time to Exhaustion)
- Fractional iron absorption
- Heart rate variability (RMSSD)

Still to read means nobody here has got to it, not that it was tried and did nothing or that no research exists. A pairing on no list is not a gap: we never set out to read it.
