Vitamin D and speciesAre species that do not have access to sunlight to synthetize vitamin D and folic acid at a significant disadvantage for their lifestyle, or have they developed ways of adequately compensating for the lack of sunlight?

Subterranean mammals had to adapt theirbiochemical pathways and cellular VDRs(Vitamin D Receptors) to cope with verylow levels of this hormone:
This would imply that one could create synthetic chemicals that could bind to the same receptors as vitamin D3 does itself, and either enhance or block the effect of the vitamin in that way.It ofcourse also leads to the question as to what is happening downstream of the VDR's?Just idle curiosity.
