Although Vitamin C is a important nutrient for people around the world. Too much intake of this vitamin can lead to numerous health issues such as harming the kidneys. Experts warn taking in extra Vitamin C daily.

Once the body has taken in too much Vitamin C the first symptoms to occur is an upset stomach and diarrhea. This generally occurs when the body consumes around 2,000 milligrams of Vitamin C daily. Another harmful side effect of too much Vitamin C intake is Kidney harm. This is due to the Vitamin C creating oxalate which can be difficult for the kidneys to remove from the body. This causes the oxalate to build up causing kidney stones.

Excessive Vitamin C intake can also cause excessive iron production. While this can sometimes be seen as a good side effect, excessive iron build-up can greatly harm the body by causing iron overload and iron toxicity in the bloodstream. This will in-turn cause long-term damage to your thyroid, heart, liver, and central nervous system.

Experts recommend adults take under 2000mg of Vitamin C per day to stay within the tolerable upper limit. This will guarantee that a person will not receive any harmful side-effects.
