When Vitamin C is obtained from food sources and supplements in the recommended dosages, it is generally regarded as safe. Though side effects are not usually reported, taking too much vitamin C can cause nausea, vomiting, heartburn, abdominal cramps, and headache. In people with a condition called hemochromatosis, which causes the body to store too much iron, high doses of vitamin C could aggravate iron overload and cause damage to body tissues.
What is important to know is that our body get enough Vitamin C to help repair and regenerate tissues, prevent scurvy, protect against heart disease, aid in the absorption of iron, and decrease total and LDL (“bad”) cholesterol and triglycerides.
Daily amount of the required vitamin can be obtained by eating at least five portions of fruit and vegetations if they are consumed raw or cooked quickly. Taking C vitamin supplements is a handy way to fill up any deficiency of the vitamin. However, with a balanced diet the quantity of c vitamin the body obtains is likely to be adequate.
