Well, direct the pedantry to yourself because you're the one using 'dawn' that way, I just used your own term back to you quoting your words used:
I say “morning” but 11-14 is basically my morning and I’m in Northern Europe. But yeah, probably best to take it dawn than dusk.
You did not say CLOSER to dawn. You said take it at dawn than dusk.
There's other reasons I think this, having to do with calcium, osteocalcin, movement, and vitamin k/food.
