The famous saying of English says that excess of everything is bad. How much is this statement true? Is it true in every case? The answer to this question is no as every component has some effects and these effects may be negative or positive. The effects vary according to the disease and condition of the body.

Kidney stones are one of the most popular diseases and a painful one too. It is believed that vitamin C is a helpful vitamin in kidney stones. Vitamin C rich diet plays a vital role in curing and preventing the disease. Recurrent kidney stones may form in patients who are sensitive to the chemical by products of animal protein and who consume large amounts of meat.

High doses of vitamin C (i.e., more than 500 mg per day) can result in high levels of oxalate in the urine (hyperoxaluria) and increase the risk for kidney stones. It is advised to the stone formers should limit their intake of cranberries, which contain a moderate amount of oxalate.

A study was undertaken to find out the relation between the intake of vitamin B6 and C and the risk of symptomatic kidney stones were prospectively studied in a cohort of 85,557 women with no history of kidney stones. Semi quantitative food-frequency questionnaires were used to assess vitamin consumption from both foods and supplements. A total of 1078 incident cases of kidney stones were documented during the 14-yr follow-up period. It was seen that a high intake of vitamin B6 was inversely associated with the risk of formation of kidney stones. On contrary it was found that Vitamin C intake was not associated with the risk of developing of kidney stones.

The latest study in support of vitamin C says that the intake of vitamin C reduces the risk of heart disease, and increased longevity, and so its use was recommended. One of the arguments against taking large amount of Vitamin C said that it increased the risk of kidney stones but the debate and the studies proved that there was no increase in kidney stones formation due to the intake of Vitamin C rather it was proved that it reduced the risk of stones formation.

The use of vitamin C is further supported by the doctors and health experts who recommend the intake of orange juice and lemonade etc other products rich in vitamin C in order to reduce the risk of kidney stones. It is also said that Vitamin C lowers the risk of recurrence of the stones in the patients prone to kidney stones or the ones who had already got the treatment for the same.
