    How much D3?

    Primal Fuel
    I'm curious about how much vitamin d3 is appropriate? I live where winter is...well, gray and nasty. I used to take 10,000 IU per day but since it's fat soluble, I didn't want to create toxic levels in my body. I took d3, however, before I went primal and now I don't take it at all. Any advice on appropriate dosage?

    Short answer 4,000 or 5,000 a day in winter.

    Will our body be able to utilise D3 ingested in this way? I need some but am concerned about throwing away my limited income on quackery...

    I self experimented and raised mine from 40 to 50 by taking 10,000/day for 3 months.

    Would dosage increase for someone who's significantly overweight?

    Dosage depends on if you are maintaining or if you are treating a deficiency. 10,000/day for a couple months is good to treat a deficiency, but then you need to re-test to determine if its time to back off to maintenance levels or not (usually 4,000 is good for maintaining but is dependent on individual, time of year and lattitude).

    you need to get your levels checked. likely you are low if you work indoors and live in the northern hemisphere.

    mine was in the low 20s so i started supplementing with 10,000 ius daily. last time i had it checked it was in the 50s. if i spend time outdoors i don't take any that day. now i maintain on 5000 ius.
    As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.

    it's not quackery at all. d3 is a vital precursor hormone that facilitates countless processes in the body and YES quality supps work in this case.
