What Happens If You Eat Too Much Vitamin C
Vitamin C: Excess of its intake can lead to iron overload in the body
Highlights
- Vitamin C is needed by the body for a stronger immunity
- Excess of it, however, can lead to formation of kidney stones
- Increase intake of Vitamin C through food sources, instead of supplements
Vitamin C is one of the most important nutrients for the body. Also known as ascorbic acid, Vitamin C is needed for growth, development and repair of body tissues. This water-soluble vitamin helps in many body functions including formation of collagen, strengthening the immune system, speeding up wound healing and maintaining cartilage, bones, teeth, etc. Along with these functions, Vitamin C is important for the body to absorb iron. Daily recommended intake of Vitamin C for adults is 65 to 90 mg. However, intake of Vitamin C beyond a certain extent can cause some side effects like digestive problems and iron accumulation in the body.
Side effects of too much Vitamin C you must take note of
Diarrhoea, nausea, vomiting, heartburn, headache and insomnia are some of the side effects of high Vitamin C intake.

1. Digestion problems
Digestion problems are most likely to be caused not by eating too much Vitamin C-rich foods but by taking supplements of Vitamin C in excess. Consuming more than 2,000 mg of Vitamin C supplements in a day can cause diarrhoea, nausea and even acid reflux.

2. Overload of iron
As mentioned above, Vitamin C is known to facilitate absorption of iron in the body. Vitamin C has the capability to bind non-heme iron, which is found in plant-based foods. Non-heme iron is not absorbed as efficiently by the body as heme iron-a type of iron found in animal foods. Taking too much of Vitamin C can lead to iron overload in the body, which can cause damage to liver, heart, pancreas, thyroid and central nervous system.

3. Vitamin C is not stored in the body
Being a water-soluble vitamin, Vitamin C is not stored in the body. Most of it gets transported to your tissues through body fluids, and the excess of it passes through urine. And when you consume excess of it in the form of supplements, it results in digestion problems.
4. Kidney stones
Excess intake of Vitamin C has also been linked to risk of kidney stones. This nutrient is excreted from the body as oxalate via urine. In some cases, the oxalate binds with minerals and form crystals, leading to the formation of kidney stones. Excess vitamin C intake can increase oxalate in urine, thus increasing risk of kidney stones as well.
