What are the different ways to counteract too much vitamin C?

Vitamin C is a very essential water-soluble nutrient that you can get from many fruits and vegetables.

It is required for normal growth and development and helps the body in absorbing iron. Since vitamin C is not produced or stored by our body, it is necessary to obtain it from the diet. 

Vitamin C is also crucial for maintaining a healthy immune system, healing wounds, strengthening bones, and improving brain activity. 

However, many vitamin C supplements consist of quite high doses, which can cause undesirable consequences in a few cases.

If you suspect you have increased levels of vitamin C in your body or are experiencing symptoms, ask a doctor or healthcare provider. The doctor may instruct you to get a blood test done. If the report confirms increased vitamin C concentration in your blood, he may ask you to:

Your doctor can then evaluate the problem and take measures such as requesting procedures or suggesting medications to help relieve your symptoms and prevent any more damage from being done to your body. If the condition prevails or you are experiencing difficulty in breathing or kidney problems, reach your doctor right away.

He may then ask you to:

Discontinue taking vitamin C supplements 

The simplest way to counteract too much vitamin C is to either reduce the daily consumption significantly or discontinue taking the supplement entirely. It doesn’t imply that you will have to quit eating vitamin C-rich fruits and vegetables.

In most circumstances, limiting the use of vitamin C supplements should work to counteract many or all overdose symptoms. 

Drink plenty of water 

Drinking plenty of water should also serve to wash out your body and help you heal from a surplus.

Nevertheless, be cautious about how much water you drink. Too much water or drinking an excessive amount of water too quickly can remarkably lower your sodium concentration which can be fatal.

Limit fruits and vegetables with high content of vitamin C

If nothing works for you and you are still facing symptoms of too much vitamin C, then another option to counteract the critical symptoms is to limit the consumption of fruits and vegetables that are rich in vitamin C. 

The fruits or vegetables you will have to watch out for include: 

  • Guava: 377 mg 
  • Kiwi: 167 mg
  • Bell peppers: 190 mg/cup with 46 calories. 
  • Berries including blueberries, blackberries, raspberries
  • Strawberries: 98 mg/cup
  • Oranges: 96 mg/cup
  • Grapefruits 
  • Clementines
  • Lemons 
  • Brussel sprouts 
  • Broccoli 
  • Cabbage 
  • Kale: 53 mg/cooked cup

Keeping in mind that a daily dose of vitamin C is required for the proper functioning of the body, you should only limit and not completely eliminate the intake of fruits and vegetables that have a high content of vitamin C. 

Symptoms of too much vitamin C

For adult men and women, the recommended daily dose of vitamin C is 65-90 mg per day, 2000 mg being the upper limit per day. 

Although too much dietary vitamin C is not likely to be harmful, excessive doses of vitamin C supplements may lead to:

  • Abdominal cramps
  • Diarrhea
  • Headache
  • Nausea and/or vomiting
  • Heartburn
  • Insomnia

In severe cases, the symptoms may include:

How much vitamin C is too much?

There is no doubt our body requires vitamin C daily to remain healthy. But that does not imply we should consume vitamin C in excessive amounts. 

In general, males who are 19 years or older require 90 milligrams of vitamin C in a day whereas females require 75 milligrams.

While smokers and pregnant women are instructed to consume slightly higher quantities of vitamin C.

Typically if you are getting your vitamin C from fruits and vegetables, you should not have to stress about taking excessive amounts. The side effects normally emerge in those people taking vitamin C supplements.

If you are taking vitamin C supplements and you ingest over 2,000 mg at one time, you may start to encounter vitamin C poisoning. At that time, you will experience some side effects.
