This disease has symptoms such as twisted, weak bones. An adult form of this disease is called osteomalacia. If there is too much vitamin D taken in, reabsorption of the bone will be seen. It may cause diarrhea and weight loss. It should be noted that vitamin D toxicity would not be caused from being in the sun too long.
Vitamin E has anticoagulant and antioxidant properties.
This is due to compounds called tocopherols. Dietary and supplemental doses of vitamin E have no known symptoms of deficiency or toxicity. The RDA is 8mg for women and 10mg for men. Vitamin K, is a little different because one of its forms can be synthesized in the stomach. Though the synthesis of K in the stomach is not enough for a dietary source, it can be also be absorbed from food.
