First off we need to realize that small amounts of vitamins A, D, E and K are crucial to maintaining a good general health. Also, as opposed with other vitamins, foods that have them included in their composition will not lose them when cooked. Our bodies do not require the vitamins each day because of the fact that they are stored in soft tissue and liver when they are not utilized and this immediately means that most people do not need vitamin supplements that contain fat soluble vitamins. The problem stands when we get higher dosage of Vitamins A, D, E and K as they can be toxic and can lead to health problems.

Vitamin A overdose is much more probable than deficiencies. A tolerable upper intake level in adults is 3,000 mcg RAE and it is very hard to reach it by only taking in the fat soluble vitamin from food. It usually happens with a vitamin supplement. Symptoms of high dosage include itchy skin, headache, nausea, dry skin and appetite loss. Severe symptoms include blurred vision, slowed growth and dizziness.

Vitamin D deficiency in children comes with some symptoms including rickets and flattening of the back area of the skull. In adults vitamin D deficiency is called osteomalacia and causes weak bones and muscular weakness. Deficiency is rare but the contrast is more difficult to handle as the tolerable upper intake is 50 mcg. High dosage can lead to accumulation in the liver and poisoning. Symptoms include slowed physical and mental growth, loss of appetite, vomiting, nausea and too much calcium in the blood.

Vitamin E overdose is dangerous for people that take blood thinning drugs and/or statin drugs. This is because it can interfere with the strength of the medication used. Vitamin K does not have an established upper intake level although excessive quantities will cause liver damage and red blood cells breakdown so it is not recommended.
