I read the article so you lot wouldn't have to. It's about a gene that makes some people metabolise caffeine three times slower than others which can cause problems at high levels of caffeine consumption. Not about coffee being harmful to kidneys in and of itself.

Personal hypothesis: I imagine 3 cups a day with an ~18 hour half-life would mean their bodies never get a break.

And if you have not had low kidney scores after a physical you’re missing that bad gene.

Damnit, here I was safe rolling on my 600+ mg of caffeine a day.

Well, I feel like I’d prolly have kidney problems by this point if I had that gene. Prolly fine. I think. Maybe. I hope.

On a rare occasion I have half a cup in the morning. Consistently sleep bad then. Sleep fine otherwise. I have wondered if this is what my issue is. Such a pity.

Also said hormonal birth control can slow down absorption and cruciferous vegetables can speed it up. Explains why coffee never works for me.
