What Happens If You Get Too Much Vitamin C

Too Much Folic Acid Can Lead To Serious Health Issues

The danger of taking too many vitamins

As stated by OASH , folic acid is an essential nutrient that everyone needs to maintain a healthy body. Folic acid, as well as folate, assists the body with making new red blood cells. Likewise, this nutrient is extremely important for those looking to get pregnant or are already pregnant. Thats because folic acid protects fetuses against potential serious birth defects. Those worried about their intake of this B vitamin should know that folic acid is found in food sources such as bread, pasta, and cereal folate is also derived from leafy green vegetables, oranges, and beans.

On the other hand, OASH stated that too much folic acid isnt good for our bodies. You shouldnt consume more than 1,000 micrograms of folic acid a day unless directed otherwise by a medical professional. Additionally, its noted that too much of this nutrient can hide signs that youre deficient in vitamin B12, which could potentially lead to nerve damage. Similarly, Healthline declared that there are three other possible side effects that can result from too much folic acid. These include an accelerated age-related mental decline, a slowdown of brain development in children, and an increased chance of cancer recurring in those with cancerous cells.

Eating Too Many Citrus Fruits

Speaking of foods and beverages, some people consume lots of citrus fruits either out of habit or because of the aforementioned desire to avoid or fight off a common cold. While citrus fruits certainly taste great, eating too much of them is never a good thing.

For one thing, its almost impossible to eat so many citrus fruits that you overdose on vitamin C. Just be aware if taking a high dose vitamin c supplement you will not need to overdue the citrus fruit.

Honestly, its a lot easier to just take a vitamin with plenty of antioxidants and vitamins found in fruits instead of trying to eat berries and citrus fruits all day . Check out Livingood Dailys Greens Berry Supplement as a perfect example.

How Much Vitamin D Is Too Much

Since relatively little is known about how vitamin D toxicity works, its hard to define an exact threshold for safe or toxic vitamin D intake .

According to the National Academy of Medicine, formerly known as the Institute of Medicine, 4,000 IU is the safe upper level of daily vitamin D intake. However, doses up to 10,000 IU have not been shown to cause toxicity in healthy individuals (

Hypercalcemia caused by regularly taking high amounts of vitamin D supplements may take a few months to resolve. This is because vitamin D accumulates in body fat and is released into the blood slowly .

Treating vitamin D intoxication includes avoiding sun exposure and eliminating all dietary and supplemental vitamin D.

A doctor may also correct your calcium levels with increased salt and fluids, often by intravenous saline.

Summary

The main consequence of vitamin D toxicity is hypercalcemia, with symptoms including nausea, vomiting, weakness, and kidney failure. Treatment involves limiting all vitamin D intake and sun exposure.

Food Sources Of Vitamin C

It is always best to get your nutrients from food rather than supplements.

Fruits and vegetables, especially citrus fruits, are good sources. Foods naturally rich in vitamin C include:

  • Raw red bell peppers: 95 milligrams per 1/2-cup serving
  • Orange juice: 93 milligrams per 3/4-cup serving
  • Orange: 70 milligrams per one medium fruit
  • Kiwi: 64 milligrams per one medium fruit
  • Raw green peppers: 60 milligrams per 1/2-cup serving
  • Cooked broccoli: 51 milligrams per 1/2-cup serving
  • Strawberries: 49 milligrams per 1/2-cup serving
  • Cooked Brussels sprouts: 48 milligrams per 1/2-cup serving
  • Tomato juice: 33 milligrams per 3/4-cup serving
  • Cantaloupe: 29 milligrams per 1/2-cup serving

If you don’t get enough vitamin C from what you eat, a supplement can help get you to the right levels.

Impair The Effectiveness Of Niacin

How Much Vitamin C Per Day Is Healthy

Evidence suggests that taking vitamin C supplements may impair the bodys ability to increase high density lipoprotein cholesterol in people taking the combination drug niacin-simvastatin. This drug combines the vitamin niacin with the statin simvastatin , and people take it to treat high cholesterol.

Doctors consider HDL cholesterol the good cholesterol because it reduces the amount of harmful cholesterol in the blood.

If a person takes vitamin C supplements and niacin-simvastatin, they should talk to their doctor about ways to make each more effective. Doctors do not know whether vitamin C also affects the ability of other medicines similar to Zocor.

A persons body cannot make vitamin C, so people need to eat enough foods that contain vitamin C to meet their daily needs. If someone is at risk of a vitamin C deficiency, they can take vitamin C supplements.

The advise aiming for the following RDA of vitamin C each day:

Age
90 mg 75 mg

People who smoke should take 35 mg more vitamin C per day than those who do not smoke.

During pregnancy or when breastfeeding, women should get the following levels of vitamin C per day:

  • 1418 years: 80 mg during pregnancy and 115 mg when breastfeeding
  • 19 years and older: 85 mg during pregnancy and 120 mg when breastfeeding

There is not enough research to suggest an RDA for vitamin C in those younger than 1 year of age. As a result, the ODS provide an adequate intake, which is the amount that is likely to be sufficient:

What Are The Side Effects Of Vitamin C

Vitamin C is generally considered safe, but high doses can cause side effects. These may include:

Higher doses are more likely to lead to side effects. Doses over 2,000 milligrams a day may increase the risk of diarrhea and kidney stones. If you have a history of kidney stones, taking more than 1,000 milligrams a day may increase your chances of having more.

Whats The Best Way To Take Vitamin C

Both experts stress that the best way to take vitamin C is through food. Whole foods contain a vitamin and micronutrient complex which cannot be fully replicated in vitamin supplements, says Dr. Serino. Also, your body absorbs more of the vitamin through food than through a supplement.

In my experience, most people do not need to supplement with vitamin C since it is abundant in food, says Greaves. The best sources of vitamin C are foods like bell pepper, brussels sprouts, strawberries, and citrus fruit. For example: A half cup of raw red pepper has about 95 mg of vitamin C.

If you dont like any of that stuff, you can eat a medium potato and a cup of red cabbage to get your daily dose. If youve got guava around, youll get 206 mg from eating just one!

Make sure to eat a few servings of fruits and vegetables each day, and youll likely have more than enough vitamin C to make your body happy. Its important to know that research doesnt show any benefit of supplementing with vitamin C beyond the recommended daily intake, says Greaves. So more is definitely not better!

Cancer Treatment And Prevention

A lot of research has investigated the role of antioxidants, including vitamin C, in cancer care and prevention. However, the results have yielded inconsistent results.

Most studies have found that vitamin C supplementation, either on its own or in combination with other supplements, cannot prevent or treat cancer.

Some studies have shown that when used in supportive care, high-dose intravenous vitamin C can improve quality of life and reduce the side effects of standard cancer treatments.

When it comes to cancer, it’s become clear that antioxidants aren’t all good or all bad. Studies have also shown that antioxidants may:

  • Help cancerous or pre-cancerous cells survive
  • Possibly make some cancer treatments less effective

Some healthcare providers recommend eating more antioxidant-containing fruits and vegetables, as people with diets rich in vitamin C may have a lower risk of getting certain types of cancer. However, it’s important to remember that no one food will prevent cancer. Moreover, vitamin C supplements themselves do not appear to prevent cancer. Eating a well-balanced diet in general, including antioxidants, is beneficial for your overall health.

Future studies are needed to establish the role of antioxidants like vitamin C in cancer. Talk to your oncologist before starting any supplements during cancer treatment.

In one study where healthy subjects were administered supplemental vitamin C every day for 6 weeks, oxidative damage was reported at a dosage of 500 mg per day. Researchers speculate that as a pro-oxidant, vitamin C supplements can alter and damage DNA and even lead to diseases like cancer. This effect was not seen in dosages less than 500 mg and may be restricted to excessive supplemental use rather than intake via natural foods. However, these claims have been disputed in other studies and will need further extensive study before it can be confirmed.111213
