      Own brand vitamin D Eileen.I was asking what is 2.5 nano grms in international units to compare to a recommendation of RDA for bit D of 600 int units

      The ng figures I'm familiar with are the blood levels - and the vit D amounts in tablets/foods are expressed in mcg or IU. I'm sending you a link by pm you may be able to work it out from. However - 1,000 IU is 25 mcg,

      The 600 IU daily recommendation is absolutely at the bottom end of the range - 2000 iu is more like it for maintenance and for replacing vit D if your level is very low you need 60,000 IU per week (3X 20,000 IU) for several weeks at least.
