Vitamin C is considered among most physicians to be a generally safe nutrient. Found in many common fruits and vegetables, when consumed in daily recommended amounts, side efects are usually non-existent; however benefits of high doses of Vitamin C don’t often outweigh potential side effects that may occur. While some studies have shown high doses of Vitamin C to be beneficial fighting some illnesses, the risk of side effects increase drastically and can be potentially deadly.
Possible Side Effects
The recommended daily intake for a healthy male over the age of 18 is 90 milligrams and for a healthy non-pregnant female is 75 milligrams. These are the doses suggested by the U.S. Food and Nutrition Board of the Institute of Medicine and should be followed unless directed otherwise by a personal physician or dietician. Depending on your own previous and current medical condition, your healthcare provider will be able to best prescribe your daily vitamin intake recommendations. Leaving your personal health to chance, by supplementing without a doctor’s care, can lead to unexpected adverse reactions. Multiple complications can arise that could even end up resulting in a trip to the local emergency room. In some rare instances, complications can be so severe that side effects remain permanent, causing life-altering changes or sometimes even resulting in death. Adverse reactions to high doses Vitamin C can include but are not limited to:
- Blood Clotting
- Kidney Stones
- Red Blood Cell Destruction
- Death (heart-related)
Vitamin C Supplements
The U.S. Drug and Food Administration does not strictly regulate herbs and supplements. It is typically suggested that the healthiest way to absorb your recommended daily vitamin intake is through a normal healthy diet consisting of fruits and vegetables. When deciding to use dietary vitamin C supplements, as opposed to normal food intake, it is important to remember not to go above the normal recommended daily dose. Injecting vitamin C in high doses can ultimately lead to kidney failure. Caution should also be used when chewing vitamin C tablets; overuse can lead to irreversible enamel erosion of the teeth.
