It's interesting the vitamin D level dropped if over exposed to UV. I wonder what caused the drop.

UVA is rather destructive, so I would assume that’s what’s going on — to much UV-A on a part of the shroom that by design is shielded from direct exposure, is basically breaking everything down.
That’s my .02.
