Vitamin C is an essential nutrient that keeps the body functioning. It includes the synthesis of collagen, healing of wounds, and repair and maintenance of cartilage, bones and teeth. Vitamin C is also an antioxidant. It is considered an immune booster and there is little evidence that it actually prevents or treats infections. The main use is to treat Vitamin C deficiency.
It is also believed to aid in the prevention of numerous diseases including colds, asthma, bronchitis, cancer, chronic pain, glaucoma, heart disease, hypertension and many other diseases. Evidence supporting these claims is weak.
Studies showed that Vitamin C did nothing to reduce the rate of colds. There is some evidence that it may slow the progression of macular degeneration or prevent certain types of cataracts.
Vitamin C is generally safe. High doses can cause adverse effects such as heartburn, nausea, headaches, cramps, diarrhea, and kidney stones. It can reduce the effects of some anti-psychotic medications. It can also raise your blood sugar.
*Always ask your doctor before starting any over the counter medication. Most Vitamin C doses can be obtained through foods such as fruits and vegetables.
