You are more likely to experience digestive-related symptoms if you consume more than 2,000 mg at a time. Therefore, a tolerable upper limit of vitamin C (TUL) of 2,000 mg per day has been established. The most common digestive-related symptoms of too much vitamin C are diarrhea and nausea.

Vitamin C can cause iron retention
Vitamin C is known enhances iron absorption. Vitamin C can bind to non-heme iron, found in plant foods. Non-heme iron is not absorbed by your body as efficiently as heme iron, which is commonly found in animal products.
Vitamin C binds to non-heme iron, making it easier for your body to absorb. This is an important function, especially for those who only consume iron from plant-based foods.
One study in adults showed a 67% increase in iron absorption when they supplemented with 100mg of vitamin C with a meal. However, people with conditions that increase the risk of iron accumulation in the body, such as hemoglobinopathy, should use vitamin C supplements with caution and should consult their doctor. Excessive vitamin C can lead to iron overload, and cause serious damage to the heart, liver, pancreas, thyroid and central nervous system of the body.
Taking vitamin supplements in high doses can lead to kidney stones
Excess vitamin C is excreted from the body as oxalates. Oxalate is normally eliminated from the body in the urine. However, in some cases, oxalates can bind with minerals and form crystals that persist in the body and lead to kidney stone formation. Too much vitamin C has the potential to increase urine oxalate levels, thereby increasing the risk of developing kidney stones.
In a study taking a 1,000 mg vitamin C supplement in adults twice daily for 6 days, excretion of oxalate in these subjects increased by 20%. Taking more vitamin C is not only associated with higher levels of urinary oxalate, but also with the development of kidney stones, especially if you take a vitamin C supplement greater than 2,000 mg.

Since vitamin C is water soluble and your body excretes excess amounts of this vitamin within a few hours of taking it, excess intake is limited. In fact, it's almost impossible to get too much vitamin C from your daily diet. In healthy individuals, when the amount of vitamin C added exceeds the recommended daily amount, it is eliminated from the body.
However, the risk of vitamin C overdose is higher when people take supplements that contain vitamin C. The side effects of vitamin C when taken in excess can be greater than 2000mg, including digestive disorders and kidney stones.
If you choose to take a vitamin C supplement, you should choose one that contains no more than 100% of your daily needs. Vitamin C products should include 90 mg per day for men and 75 mg per day for women.
You should never take vitamin C supplements without your doctor's supervision. Consuming large doses of vitamin C and stopping suddenly can cause serious complications.
