Negative Side Effects Of Too Much Vitamin C
Introduction
Vitamin C, also known as ascorbic acid, is an essential nutrient that our body needs to maintain good health. It is found in many fruits and vegetables, and is often taken as a supplement to boost the immune system and prevent colds and other illnesses. However, too much of a good thing can be harmful, and excessive intake of vitamin C can have negative side effects on our health.
What Is The Recommended Daily Intake Of Vitamin C?
The recommended daily intake of vitamin C varies depending on age, gender, and other factors. For adults, the recommended daily intake is 75-90 milligrams per day. However, some people may need more vitamin C, such as pregnant women, smokers, and people with certain medical conditions.
What Are The Negative Side Effects Of Too Much Vitamin C?
While vitamin C is generally safe when taken in recommended doses, excessive intake can lead to negative side effects. Some of the most common side effects of too much vitamin C include:
Gastrointestinal Problems
High doses of vitamin C can cause gastrointestinal problems such as diarrhea, nausea, and stomach cramps. This is because vitamin C is a water-soluble vitamin, which means that excess amounts are excreted in the urine. When taken in large doses, the body may not be able to absorb all of the vitamin C, which can lead to gastrointestinal problems.
Kidney Stones
Excessive intake of vitamin C can increase the risk of kidney stones, especially in people who are prone to developing them. This is because vitamin C is converted into oxalate, which can accumulate in the kidneys and form stones.
Iron Overload
High doses of vitamin C can increase the absorption of iron from food, which can lead to iron overload in people who are already at risk of this condition. Iron overload can cause damage to the liver, heart, and other organs.
Interference With Medical Tests
Excessive intake of vitamin C can interfere with certain medical tests, such as blood glucose tests and stool tests for colon cancer. This is because vitamin C can affect the accuracy of these tests, leading to false results.
Conclusion
Vitamin C is an important nutrient that our body needs to stay healthy, but excessive intake can have negative side effects. If you are taking vitamin C supplements, it is important to follow the recommended daily intake and talk to your doctor if you have any concerns. By being aware of the potential negative side effects, you can make informed decisions about your health and well-being.
