"Source Naturals Vitamin D-3 2000 Iu, 200 capsules for $8 on line from vitamin shoppe or $14 in store."
If you have access to Costco you can get 5,000 IU of D3 - 500 capsules for $12.50 (S&H included) at:
As I've posted before, I take 10,000 IU daily. Took 50,000 IU for several months until my doc said that it was raising my creatine levels too high (which causes kidney problems) - was over 2.00 so D/D3 is not without risks at high levels.
I subscribed to Consumer Labs for a year who tests the content of vitamins and supplements compared to what is advertised on the bottle and the Costco/Kirkland brand was always within the amounts listed as was all supplements that Costco carries. (trunature is owned by Costco.) There are others that are good too - not just Costco, but the content of many national brands that were not only nowhere near what the label said, they had loads of pure garbage in them too.
