Is there any research out there which links moderate amounts of vitamin D (such as the recommended dosages on vitamin D supplements) to any negative effects at all?
Is there any research to indicate that a lack of urushiol has negative effects, similar to how we know that a lack of vitamin D has negative effects?

If not I don't really see the connection
