This post checks out the total security of vitamin C, whether it’s possible to consume too much, and the potential unfavorable impacts of taking big dosages.

Vitamin C Is Water-soluble and Not Saved in Your Body

Vitamin C is a water-soluble vitamin, which implies it dissolves in water.

In contrast to fat-soluble vitamins, water-soluble vitamins do not get kept within the body.

Instead, the vitamin C that you take in gets transferred to your tissues through body fluids, and any extra gets excreted in urine.

In basic, these side effects do not take place from eating foods that contain vitamin C, but rather from taking the vitamin in supplement kind.

You’re probably to experience digestion signs if you consume more than 2,000 mg at as soon as. Therefore, a tolerable upper limit (TUL) of 2,000 mg per day has actually been developed.

Vitamin C binds with non-heme iron, making it a lot easier for your body to take in. This is an essential function, especially for people who get most of their iron from plant-based foods.

One research study in grownups discovered that iron absorption increased by 67% when they took 100 mg of vitamin C with a meal.

Nevertheless, people with conditions that increase the danger of iron build-up in the body, such as hemochromatosis, need to be mindful with vitamin C supplements.

Under these circumstances, taking vitamin C in excess may cause iron overload, which can trigger major damage to your heart, liver, pancreas, thyroid, and central nervous system.

That said, iron overload is highly unlikely if you do not have a condition that increases iron absorption. Furthermore, iron overload is most likely to occur when excess iron is consumed in supplement type.

High vitamin C intake is not only associated with greater amounts of urinary oxalate but also linked to the development of kidney stones, especially if you take in quantities higher than 2,000 mg.

Reports of kidney failure have likewise been reported in people who have taken more than 2,000 mg in a day. However, this is exceptionally rare, particularly in healthy people.

How Much Vitamin C Is Too Much?

Because vitamin C is water-soluble and your body excretes excess quantities of it within a couple of hours after you consume it, it’s rather difficult to take in too much.

Nevertheless, the risks of vitamin C overdose are higher when people take supplements, and it is possible to consume excessive of the vitamin in some situations.

For instance, those with conditions that increase the risk of iron overload or are susceptible to kidney stones must be mindful with their vitamin C intake.

All the negative results of vitamin C, consisting of digestion distress and kidney stones, appear to happen when people take it in mega dosages higher than 2,000 mg.
