Vitamin C Overdose & Deficiency

Vitamin C, or ascorbic acid, is a water soluble vitamin and the body will only use what is required and eliminate the rest, leading people to assume that the risk of overdose is non existent. However there is a growing concern that mega doses of this vitamin can have negative consequences and overdoses may be possible.

Due to well known vitamin C  benefits for general good health and particularly in cold and flu season, many people load up on mega doses of Vitamin C believing they can suffer no ill effects.

But in spite of the fact that vitamin C is not stored in the body and whatever the body does not use will be eliminated, there is the possibility in extended periods of excessive doses, for the vitamin to do the damage before it is excreted.

The recommended daily dose for Vitamin C is 90 mg. However many people take in excess of 1,000 mg daily. These people are more at risk for overdose along with the consumption of other vitamins and nutrients due to the interaction between them.

Some indicators of Vitamin C deficiency are weakness, fatigue, and irritability. Signs of a severe deficiency, also known as scurvy, are anaemia, bruising easily, dry hair and skin, and gum and dental problems.

Vitamin C deficiency is generally caused by lack of proper dietary sources such as fresh fruits and vegetables although there are other possible causes. Cooking does destroy some of the vitamins in foods and so fresh fruits and vegetables are the more desirable choice. There are other conditions which can increase the body’s need for vitamin c and therefore cause a deficiency if intake is not increased as well, such as pregnancy, breastfeeding, surgery, severe burns and some disorders causing inflammation and/or high fever.
