I think the ONLY issue here is that there is a big confusion about the stages of VitD.
No food nor supplement will ever supply an activated version of VitD.
The supplements are worse since they single out one toxic element required to produce this activated hormone.
We don't supply homocysteine to boost methylation why would we supply a toxic precursor and neglect to even test what it is we where supposed to boost (assuming it was needed)?
This is made worse since we know that if the body is unable to convert that toxic pre-cursor, it will effectively plug all receptors that may still be functioning.
