I am suffering from vitamin d deficiency and my doctor prescribed 1 / 1000iu tablet daily. how long will take me to recover?

To low a dose!: Vitamin d repletion takes longer when you have more body fat, since it is a lipid soluble vitamin, and your general size, independent of leaness. Usually on your dose you should see a significant rise in 4-6 weeks, but not knowing how low you were & if you are overweight, it may be from 3-9mo before you d is adequate! key factors: size; how low you were; & degree of obesity! your dose is too low!
