We know that eating vitamin C is needed to strengthen our immune system to fight sickness and some of us may like to consume more vitamin C than our daily needs. However, consuming excessive vitamin C will harm the body.
A research from Stockholm shows that daily consumption of 1000 to 2000 mg of vitamin C may increase risk of cataract, kidney stones, and even knee arthritis.
Sweden research indicate that excess vitamin c in our body will be converted to oxlate, and passed out of our body through the urine. When oxlate and calcium level in our kidneys are too high, kidney stones will form.
