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

It's unstable under overexposure of uv light

I think vit. D is generated from a reaction of a protein with UVB.

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.

perhaps UV?
