Vitamin D Side Effects and Vitamin D Overdose

Vitamin D is found in oily fishes such as anchovies, cod, sardines, herring, mackerel and tuna. It is also found in eggs, beef, liver, cheese, Portobello mushrooms, and milk. Most of the vitamin D you acquire comes from sunlight. Cholesterol in your body is converted into vitamin D in your skin. Two to three times a week for 10 to 15 minutes a day will do it. Vitamin D is important for laying down calcium in bone and teeth and a deficiency causes rickets, a condition known as soft bones. Vitamin D is also used as a form of therapy for cardiovascular problems stemming from hypertension (high blood pressure) and high cholesterol levels. It is also used to treat vitiligo, scleroderma and psoriasis. Vitamin D is also used to boost the immune system to prevent autoimmunity and cancer. However, high doses can cause severe vitamin d side effects.

Despite the foods we eat, supplementation and sunlight, some people find themselves deficient in vitamin D. Some people try to supplement themselves to resolve this issue however, that is the wrong thing to do because it is too easy to overdose generating vitamin d side effects. Consult with your healthcare provider before you supplement. It’s better to get some sunlight than it is to supplement. Depending on where you read the daily recommended dose varies however it has been suggested by the Institute of Medicine that adults should take up to 4,000 IU and children should have 2,500 IU. Some healthcare professionals think this is conservative but certainly adequate and should not produce any vitamin d side effects.

There are many vitamin d side effects which are listed below. These are the most common reported by healthcare practitioners and patients and by no means exhaustive. If you experience any of these side effects, contact your doctor immediately.

Overdoses of vitamin D cause elevated levels of calcium in your body. This excess calcium will begin to deposit in cells of major organs and tissues causing them to calcify. In essence, your organs are turning to stone like your bones. This is a very serious condition indeed. This is true of your arteries as well. While all of this is happening your kidneys are shutting down. Vitamin D side effects due to an overdose have far reaching consequences. Be very careful about supplementation and talk with your doctor before you do so. If you have a vitamin D deficiency, this may due to a preexisting medical condition that needs to be diagnosed. Don’t ignore your health, seek medical attention.
