I've been supplementing 5000iu per day over the last 3+ years. I work indoors and go to school so I don't get as much sun as I used to but still try to get a little when I can.
A recent blood test showed my vit D, 25-hydroxy at 69.3 ng/ml. My practitioner said that looks great and to keep doing what I'm doing. A recent podcast from a trusted source recommended levels of 50 ng/ml and not to go much above or beyond that level. I know my level isn't that far off but it's the highest it's been in my life. Do I continue doing what I have been or should I cut back on supplementation?
Other Factors in line with this topic:

I saw in another thread you recommended against taking CLO and Mag citrate (or any other forms ending in "ate"). To my knowledge nearly all other trusted sources I follow recommended the complete opposite. The reason being is that humans don't convert beta-carotene into the active Vitamin A form very efficiently and the "ate" forms of magnesium are the most bioavailable. Can you please explain your position so I better understand?
Finally based upon info from the same sources, I don't supplement any form of calcium but i see you recommend to. Being that I do take mag daily, would it be in my best interest to add a calcium supplement? If so, what form and dosage?
