If you experience gastrointestinal issues, cut your dose in half.

How To Handle An Overdose On Vitamin C

If youre healthy, theres no way you can die from a Vitamin C overdose. However, if you do have health conditions, taking too much Vitamin C in supplement form can have some serious consequences.

If youre experiencing symptoms such as nausea, cramping or headaches, you could also benefit from using some over-the-counter drugs.

If you suspect youre overdosing on Vitamin C and youre taking prescription medicines or have a health condition, speak with your doctor. And, if the conditions persist or youre experiencing serious side effects such as difficulty breathing or kidney stones, contact your doctor.

Your physician can then assess the situation and take actions such as ordering tests and procedures and/or offering a prescription to help ease your symptoms and preventing any further harm being done to your body.

Can You Overdose On Vitamins Watch For These Symptoms

Weve all heard the saying, Too much of a good thing is bad for you. But what about when it comes to vitamins? Can you ever really overdo them?

Yes, absolutely, said Dawn Gerber, PharmD, a clinical ambulatory pharmacy specialist with Banner Health. Basically, there are two types of vitamins: water-soluble and fat-soluble. Although your body can excrete large amounts of water-soluble vitamins, it holds onto fat-soluble vitamins, which can be toxic at high levels.”

Water-soluble vitamins, like vitamin C and B-complex, are carried to the bodys tissues and arent stored in your body. Fat-soluble vitamins, like A, D, E and K, are absorbed along with fats in your diet and are stored in your bodys fatty tissue and in the liver.

These get caught in our fat, the non-muscular parts of our bodies, Dr. Gerber said. The more supplements we take at high doses, the more that accumulates and isnt flushed out.

While its hard to overdose just eating these vitamins naturally with a well-balanced diet, vitamin supplements can have negative ramifications.

Heres what you need to know to avoid overdoing it in the supplement department.

How Much Vitamin C Is Too Much

Since vitamin C is water-soluble and your body excretes excess amounts of it within a few hours after you consume it, its quite difficult to consume too much.

In fact, it is nearly impossible for you to get too much vitamin C from your diet alone. In healthy people, any extra vitamin C consumed above the recommended daily amount simply gets flushed out of the body .

To put it in perspective, you would need to consume 29 oranges or 13 bell peppers before your intake reached the tolerable upper limit (

19 ).

All the adverse effects of vitamin C, including digestive distress and kidney stones, appear to occur when people take it in mega doses greater than 2,000 mg .

If you choose to take a vitamin C supplement, it is best to choose one that contains no more than 100% of your daily needs. Thats 90 mg per day for men and 75 mg per day for women .

Summary:

Its nearly impossible to consume too much vitamin C from food. However, if youre supplementing with this vitamin, you can minimize your risk of getting too much by taking no more than 90 mg per day if youre a man, or 75 mg per day if youre a woman.

Vitamin C is generally safe for most people.

This is especially true if you get it from foods, rather than supplements.

Individuals who take vitamin C in supplement form are at greater risk of consuming too much of it and experiencing side effects, the most common of which are digestive symptoms.

The Health Benefits Of Vitamin C

No one vitamin can override serious health problems. They often work together â and other lifestyle habits â like getting enough sleep and exercise, and not smoking â are key. That said, research shows that vitamin C may offer health benefits in these areas:

1. Stress. A deficiency in vitamin C is associated with many stress related disease. It is the first nutrient to be depleted in alcoholics, smokers, and obese individuals. And because vitamin C is one of the nutrients sensitive to stress, Moyad says naintaining levels of vitamin C can be an ideal marker for overall health.

2. Colds. When it comes to the common cold, vitamin C is not a cure, but some studies show that it may help prevent more serious complications. “There is good evidence taking vitamin C for colds and flu can reduce the risk of developing further complications, such as pneumonia and lung infections,” says Moyad.

3. Stroke. Although research has been conflicting, one study in the American Journal of Clinical Nutrition found that those with the highest concentrations of vitamin C in their blood were associated with 42% lower stroke risk than those with the lowest concentrations. The reasons for this are not completely clear. But what is clear is that people who eat plenty of fruits and vegetables have higher blood levels of vitamin C.

Can We Overdose On Vitamin C

Yes, you can. Many people assume that since vitamin C is a water-soluble vitamin, you can never take too much of it. Their reasoning is that youll essentially just pee out any excess. Although this is true, if you take more than the amount your body is able to excrete, it will not go over well. Side effects include nausea and diarrhea two things any sane person should avoid.

Getting Vitamin C From Food

People consuming vitamin C from dietary sources probably will not reach the 2,000 mg maximum intake recommendation. For example, red peppers are a high-content vitamin C food. But one-half cup of raw red peppers only contains 95 mg, meaning someone would need to consume over five cups of raw red peppers in one day before reaching the 2,000 mg limit .

Oranges also have a lot of vitamin C, but one medium orange only contains 70 mg. This means that someone would have to consume almost 29 oranges in one day before meeting the maximum recommended intake .

Effects Of Mega Doses Of Vitamin C

How much Vitamin C is too much?

So, most healthy people need around 100 mg of vitamin C a day. Way less than 1,000 mg, which is found in many supplements.

The regular consumption of 1,000 mg of vitamin C is pretty safe, though.

According to a study, researchers have treated cancer patients with high dosages of vitamin C, through IVC therapy . Scientists gave cancer patients up to 100 g of vitamin C a day! Thats 100,000 mg. 100 times more vitamin C than the 1,000 mg dose, or 100,000 times the recommended daily intake of vitamin C. Thats a huge dose. So, what happened to these patients?

Regarding cancer, researchers observed:

  • improvement in the quality of life,
  • improved tolerance of conventional therapy,
  • deterioration in clinical condition, in the absence of vitamin C dosage.

On the other hand, the side effects of mega dosages of vitamin C seem to be minimal. Patients experienced symptoms of Jarisch-Herxheimer reaction. This is a reaction of the body to endotoxins produced by the necrosis of harmful cells. Fever, chills, strong body odor, and pimples may be other side effects.

Dont forget that these side effects happened to cancer patients, after megadoses of vitamin C. Symptoms resolved after 2 to 3 hours, after injection with vitamin C.

Most noteworthy, therapy with high dosages of vitamin C may:

  • stabilize cancer,
  • reduce the risk of metastasis,
  • keep tumor stable,
  • have antitumor activity in some cases,
  • help patients regain strength.

Overloading On Vitamin C

Ive been taking an average of 2,000 mg of vitamin C daily. Is that too much? Ive been warned that it can cause kidney stones.

Andrew Weil, M.D. |May 23, 2018

Vitamin C is a water-soluble vitamin and powerful antioxidant, and helps the body form and maintain connective tissue, including bones, blood vessels, and skin. Research also indicates that it may help protect against a variety of cancers by combatting free radicals and helping neutralize the effects of nitrites .

Vitamin C is abundant in many fresh vegetables and fruits. The best food sources include citrus fruits, red peppers and sweet potatoes. When obtained from food and supplements in the recommended dosages, vitamin C is generally regarded as safe. High doses arent known to cause serious side effects but can lead to diarrhea, nausea, abdominal cramps, and other gastrointestinal symptoms as well as heartburn, headache and insomnia.

Doses greater than 2,000 mg/day may contribute to the formation of kidney stones, but evidence for this is inconclusive.

The second study came from the Linus Pauling Institute and was published in the June 1999 issue of the American Journal of Clinical Nutrition. It identified a similar dose, 120 to 200 mg, as the optimal amount for reducing the risk of cardiovascular disease, cancer, cataracts and other chronic conditions.

Can I Take 2000mg Of Vitamin C At Once

2000 mg of vitamin C per day, or at once, is the peak limit for the allowed dosage of this vitamin. Still, we dont encourage consuming that amount on a daily basis without a consultation from your doctor.

Thats because this might only be required in case of the complete absence of any other sources of vitamin C present in the food you ought to be consuming throughout the day. Nevertheless, if you have an established healthy diet including different fruits and vegetables, then you cant ever require taking yourself to the upper limit.

Maximum Safe Intakes Of Vitamins E And C

The UL is defined by the FNB as the highest daily nutrient intake that is likely to pose no risk of adverse health effects to almost all persons in the general population. The UL method is an adaptation of a general method in quantitative toxicology. It is similar to but has important differences from the acceptable daily intake method that is widely used to set regulatory limits for food additives and pesticide residues in foods. Both the UL and the acceptable daily intake involve identification of an intake that is a no-adverse-effect level or a lowest-adverse-effect level , evaluation of uncertainty, and calculation of an intake that is expected to carry no significant risk of adverse effects, ie, the UL or acceptable daily intake. The UL and acceptable daily intake methods differ markedly in the way they address uncertainty. The UL method uses uncertainty factors that are fully derived from the specific database for each substance under consideration. For derivation of a UL from human data, the FNB has utilized UFs that range from 1 to 5, with values of 1.5 to 2 being most common. When deriving the UL from animal data, higher uncertainty factors are used to account for the uncertainties in extrapolation between species.

The NOAEL data are selected on the basis of considerations of evidence of causality, relevance, and the quality and completeness of the database. The UL is calculated as

Dietary Reference Intakes For Vitamins E And C

The Food and Nutrition Board of the Institute of Medicine, a part of the US National Academies, has established a system of dietary reference intake values for the US population that, for the first time, provides advice on the safety of the nutrients. Safety is defined as presenting no unreasonable risk of illness or injury or a reasonable certainty of no harm, under labeled or ordinary conditions of use, as set forth in US laws and regulations for dietary supplements and food additives. The DRI system includes the estimated average requirement, the recommended dietary allowance , and the tolerable upper intake level . The RDA represents the recommended daily intake for meeting normal nutritional needs and preventing clinical deficiency. Compared with the previous RDA, the new recommendations for vitamin E have been increased by 50% for men and by almost 100% for women. Similarly, the new recommendations for vitamin C have been increased by 25% for women and by 50% for men. The DRI values include a UL, which is the maximum amount considered safe for healthy people when used daily for long periods. The RDA and UL values are based on exhaustive reviews of the scientific literature. RDA and UL values for vitamins E and C are shown in .
