The recommended Vitamin D dose for women is 400 IU. You should not go over in supplementation. Vitamin D is a fat-soluble vitamin which means the vitamin goes into our fat cells and the body does not excrete it. 2000 IU is the tolerable upper intake level for adults; supplementation over that may cause a risk for toxicity (increased calcium, weak muscles, weak bones, excessive bleeding, severe headaches, and kidney stones). Vitamin D is available through our foods - Fortified milk, breakfast cereals, egg yolks, fatty fish, and fish oils. Sit at a window with the sun shining in for about 1/2 hour (few times a week) and that will help you get enough Vitamin D. Suggest you stop taking the vitamin D supplements, restrict your intake of calcium, and see your MD.
