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).
