Still wondering if you have the same concerns about the long-term effects of iron intake as you do about medications, or if you're somewhat selective about which long-term effects of chemicals in the body terrify you.

But yes, I do think the benefits for my mental health very clearly outweigh the theoretical risks you posit. So even if I agreed with what you're saying (which I don't), a subtle hammer tap to the soul is still very clearly and obviously better than the sledgehammer to the soul that is sleep deprivation (something that I concretely know would impact my brain function as I age and that I concretely know makes me less of myself). If that causes you to raise your eyebrows, then I'm not sure what to say other than that you're bad at risk analysis.
