Possibility Of Cardiovascular Disease

Side Effects Of Taking Too Much Vitamin C

Vitamin C is well known for its antioxidant properties that protect the body from diseases. But can one have too much of a good thing? Possibly, under some conditions. One study showed that high doses of vitamin C supplements can trigger cardiovascular disease in individuals who already have other underlying health conditions consuming over 300 mg per day of vitamin C supplements was associated with cardiovascular disease among postmenopausal women with diabetes. However, this was observed only in a single study and is not established firmly yet.10

Side Effects Of Vitamin B2 Overdose

Taking too much vitamin B2 is also rare, but there are side effects to consider of a riboflavin overdose.

Too much vitamin B2 side effects include increased urine frequency, diarrhea, allergic reactions like hives, difficulty breathing, and swelling of the tongue or face. Vitamin B2 will also cause the harmless side effect of turning your urine to a yellow-orange color.

Medication interactions associated with vitamin B2 include zidovudine , didanosine, doxorubicin, oral contraceptives, tetracycline, and tricyclic antidepressants.

How much vitamin B2 should you take? According to the Institute of Medicine at the National Academy of Sciences, the following is the recommended dietary allowance for vitamin B2 daily:

  • Males 14-plus years: 1.3 mg
  • Females 14 to 18 years: 1.0 mg
  • Females 19-plus years: 1.1 mg
  • Pregnant females: 1.4 mg

You can also get vitamin B2 from food. Whole foods high in vitamin B2 include:

  • collard greens
  • mushrooms

Is Vitamin A Destroyed By Heat

Vitamin A is soluble in oils and fats. The vitamin is not easily destroyed by heat but is readily oxidized. Preparations must, therefore, be protected from oxidation and are prepared in an atmosphere of carbon dioxide or nitrogen. In the absence of air, vitamin A is unaltered at moderate temperatures.

What Are The Key Ingredients In Emergen C And What Do They Do For Your Immune System

Vitamin C is the number one ingredient in all the different versions of Emergen-C. You can think of it as the hero ingredient. The powdered products and chewables all have 1000 mg of vitamin C, while the gummies tend to have lesser amounts because there is only so much vitamin C that can be mixed into a gummy without making it taste gross. Vitamin C is by far the most well-known ingredient for immunity, going back many decades to the advocacy of the renowned chemist, Linus Pauling. For more background, you can check out these pages on the Linus Pauling Institute and the NIH Office of Dietary Supplements fact sheet.

Some people think that the effect of vitamin C on immunity has been debunked, but a number of clinical trials have proven that it works to help shorten respiratory tract infections. This is especially true in people under physical stress, like soldiers and marathon runners. The caveat is that you do need to take a significant amount every day to get the job done, at least 200 mg, and many studies have shown benefits with 500-1000 mg per day.

Emergen-C also has other ingredients that are important for the immune system. B vitamins like thiamin, riboflavin, niacin, B6, B12, and folate are all essential for immune cell production. It also has zinc, an essential mineral that plays a role in a huge number of physiological processes. Zinc is well known to support immune system health.

Subtle Signs You’re Getting Too Much

Supplement warning: THIS is what happens if you have too ...

“I have not seen someone off the street who was taking a toxic level of vitamin A or D — those are very unusual,” says David Katz, MD, director of the Yale University Prevention Research Center in New Haven, CT, whose medical practice specializes in nutrition. “What I’m more likely to see is a person with a dosing level of supplements that’s higher than optimal.”

Scientists don’t yet know if routinely getting a little bit too much of a vitamin or mineral is a problem, Katz says.

“There might be hints of concern, but they would be very subtle signs,” he says.

These fairly mild symptoms may include difficulty sleeping or concentrating, nerve problems such as numbness or tingling, or feeling more irritable — depending on the nutrient that’s going overboard.

The bigger concern, Katz says, is that we’re “garnishing the food supply with overfortification.”

He says manufacturers have shifted their focus from what they’ve taken out of food — such as its fat, sugar, or salt — to what they’re putting in, whether it’s vitamin D, probiotics, or omega-3 fats — whatever nutrient is in vogue.

“When more and more foods are enhanced, it becomes impossible for consumers to know what dose they’re getting over the course of a day,” Katz says. “Clinicians have to realize we might be introducing new dietary imbalances because of this practice.”

How Can You Tell If Your Vitamin C Product Is Too Strong For You

In people that have extremely sensitive skin, you may have a slight irritation to Vitamin C serums. Irritations are more common with the higher strengths of Vitamin C serums, and may be caused by the more acidic pH of Vitamin C.

Your skin should feel good after an application of your Vitamin C cream or serum, so if you are experiencing redness, itching, burning, or stinging, you may want to opt for a weaker formulation or try blending your product with a gentle moisturizer to dilute it.

How To Treat And Prevent Vitamin C Overdose

The single best way to prevent vitamin C overdose is to avoid taking supplements in high doses and to get the vitamin C your body needs from foods instead, especially fresh vegetables and fruits. Some of the foods richest in vitamin C include citrus fruits like oranges, leafy green vegetables, red peppers, melon, berries, kiwi, mango and sweet potatoes.

As mentioned above, vitamin C is water-soluble. What does this mean in terms of getting extra vitamin C out of your body? Do you pee out excess vitamin C?

Because vitamin C is water-soluble, its not as risky to take too much vitamin C as it is to take fat-soluble vitamins like vitamin A or D. Unmetabolized ascorbic acid is excreted in the urine.

That said, overdose of vitamin C is still possible if someone takes supplements in high doses for an extended period of time, especially if that person also consumes lots of vitamin C from his or her diet and/or fortified foods.

How long does it take to get vitamin C out of your system?

Vitamin C can stay in the body for weeks. However, excess amounts are usually urinated out in a matter of hours.

Vitamin C will stay in someones body longer if that person doesnt already have high levels or are deficient. In order to prevent vitamin C from being lost in the urine, its best to take smaller, multiple doses spread out throughout the day.

How Much Should I Have Every Day

Taking Supplements In High Doses May Lead To Kidney Stones

Excess vitamin C is excreted from the body as oxalate, a bodily waste product.

Oxalate typically exits the body via urine. However, under some circumstances, oxalate may bind to minerals and form crystals that can lead to the formation of kidney stones .

Consuming too much vitamin C has the potential to increase the amount of oxalate in your urine, thus increasing the risk of developing kidney stones .

In one study that had adults take a 1,000-mg vitamin C supplement twice daily for 6 days, the amount of oxalate they excreted increased by 20% .

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 consume amounts greater than 2,000 mg (


Consuming too much vitamin C may increase the amount of oxalate in your kidneys, which has the potential to lead to kidney stones.

You Have Too Much Vitamin C If This Happens To You

Vitamin C is one of the most popular nutritional supplements around, available in everything from standard pills to chewable tablets and gummies. It’s a key nutrient in the body, responsible for maintaining strong bones, improving brain function, facilitating wound healing, and keeping the immune system strong, according to Healthline. Anecdotally, many people also believe it wards off colds.

Vitamin C is readily available in many foods, including citrus fruits, strawberries, broccoli, kale, sweet potatoes, and peppers, according to WebMD. Because of this, it’s generally easy to get the recommended daily amount from your diet. For adults, that RDA equals 90 milligrams for men and 75 milligrams for women.

If you’re also taking a vitamin C supplement, it’s important to check the bottle for the dosage. That’s because many supplements are high in milligrams, and too much of this vitamin can lead to some unpleasant, though not necessarily dangerous, side effects.

A maximum of 2,000 milligrams of vitamin C daily is considered safe for most adults. Vitamin C is water-based, so anything your body cannot use is simply flushed out in urine, according to Healthline.

What Happens When You Overdose On Vitamins?

While vitamin C is well-known for its antioxidant properties, some evidence point to its pro-oxidant tendencies in certain circumstances one of them being higher dosages. 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
