I had blood tests done found out I'm vitamin d defecient I'm not sure how bad it is I'm taking 2000iu a day is this enough?

Listen to your body. In canada one can not get sufficient vit d from sun from sept to april because of the slant of the sun. Tobacco, alcohol, stress, and lack of exercise lower vit d levels possibly through effects of free cadmium. In addition to taking supplemental vit d3 up to 10, 000 units a day with vit k2 100mcg a day it is a good idea to optimize health.
