  • D-3 Summer v Winter Dosage

    Hard to believe I was roasting in the sun and swimming in Maine just 2 weeks ago with snow in the forecast for Thu night. So as the clocks change here in the northern hemisphere and the daylight dwindles what do folks that supplement vitamin D do as far as dosage? Amt. +/-/=?

    Same dose all year for me. 5000iu. I'm in NE Ohio. There are other things that can affect D levels so I stay on the same amount all year.

      I do the same as pyro - 5000iu/day regardless of being out in the sun or not.

          My naturopath has me on 4,000 IUs and will test my levels by late winter.

            i double it in the winter

            whatever it is, you double it, do not worry about this

              i do 15,000 iu in the winter...and 10,000 in the summer months depending on how much sun i get. you'd have to be throwing back a handful of supplements to overdose, so don't be afraid to go for a big number if it keeps you healthy and feeling good.

                I do 10,000 IU Daily all year. But I work indoors & I don't get much direct sunshine. However when I feel a chest cold starting, I immediately double to 20,000 IU until it passes. Ditto for a sore throat, or any other illness.

                You can get very inexpensive Vitamin D3 testing either at home $65 or at a nearby lab $50. Details below the line.

                The main factor is how much direct sunshine do you get ( NO Sunscreen ) in the summer. If you get enough, you don't need any D3 supplements.

                  I don't take any in July and August when I get plenty of sun.....6000iu the rest of the year.
