Hi Socarp:
Taking 1200 IU of vitamin D3 daily will not make a significant change in your vitamin d3 level,
if even you take this dose for a decade. This dosage, most probably, will maintain your level at 7,
and will not let it go even lower ! Please, visit an up to date doctor in regards to vitamin D3. If an elevated
level of D3 does not improve your mood, then consider other options.
With the right dosage of D3, within three months, your level will rise considerably, and then,
it will be easier for you to decide about a new course of action, or inaction.
Best wishes,
Ali
