Antioxidants like vitamin C do seem to reduce the oxidative stress associated with these diseases. This can happen when there are too many free radicals in your body.

A 2013 review found that vitamin C may help prevent stroke. This was mostly true for people who had low intake of vitamin C before treatment or were at high risk for stroke.

The review only found this benefit for vitamin C from food sources, not from supplements.

A 2013 review noted that high intake of vitamin C does seem to be associated with a lower risk of certain cancers. It also noted that intravenous vitamin C has been shown to improve outcomes for cancer patients.

Many experimental cancer therapies include using vitamin C along with other treatments, however. This makes it hard to know how much of an impact vitamin C has on its own.

Drink plenty of liquids while you are taking ascorbic acid.

The chewable tablet must be chewed before you swallow it.

Ascorbic acid gum may be chewed as long as desired and then thrown away.

Do not crush, chew, or break an extended-release tablet. Swallow it whole.

Measure liquid medicine with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Keep the orally disintegrating tablet in the package until you are ready to take it. Use dry hands to remove the tablet and place it in your mouth. Do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing. Swallow several times as the tablet dissolves.

Is Your Multivitamin To Blame For Hypercalcemia

Can taking too much vitamin C hurt your body?

Do you usually pop an antacid when you have an upset stomach? If you said “yes,” you’re not alone, but keep in mind those antacids contain calcium carbonate, and they along with calcium supplements and many multivitamins can up your calcium levels . In fact, overdoing it on the dietary supplements or over-the-counter medications are a leading cause of potentially dangerously high levels of calcium in the body, or what is known as hypercalcemia.

As Healthline explained, the symptoms of hypercalcemia can be as mild as fatigue or headaches to as severe as abnormal heart rhythms and even coma. Excessive thirst and urination, kidney stones, nausea, vomiting, constipation, decreased appetite, pain in the abdomen, bone pain, muscle cramps and twitching, osteoporosis, and bone fractures can all be the results of too much calcium. Neurological symptoms of hypercalcemia can also be serious and include depression, irritability, confusion, and memory loss.

While contacting your health care professional about any of these symptoms is important, Healthline advised reaching out for help right away if you also have cancer. Besides supplements and antacids, cancer alone can raise calcium levels, which is considered a medical emergency.

Possibility Of Cardiovascular Disease

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

The Best Vitamin A Sources

As previously mentioned, most people get an adequate amount of vitamin A from the foods they eat. If you have concerns about getting too much vitamin A, NIH recommends you limit your intake of liver and cod liver oil, which have high concentrations of preformed vitamin A.

For perspective, a 3.5-ounce portion of braised beef liver has 9,363 microgram RAEs, which is more than three times the UL. Eggs are also a source of preformed vitamin A, but one large egg has only 90 microgram RAEs of vitamin A.

Though liver contains high amounts of vitamin A, you don’t need to completely cut it from your diet, unless advised to do so by your doctor. However, you should limit the amount of liver you eat every month to reduce risk of toxicity.

To meet your daily needs, you can include these healthy vitamin A sources in your diet:

  • Sweet potatoes

Why Do We Need Vitamin C At All

Can I Take Too Much Vitamin C?

Ascorbic acid is a water-soluble vitamin found in a variety of fruits and vegetables. Often, we think of citrus fruit as the best vitamin C delivery system, but you can also get it from peppers, tomatoes, and cauliflower.

Once its in your system, the C helps your immune system function at its best and protect against damage from free radicals. Plus, ascorbic acid is needed to make collagen, that wondrous protein that helps heal wounds and keep our skin looking young and lovely .

Our bodies cant make vitamin C on their own, so its important that we get enough ascorbic acid from food or other outside sources.

Vitamin C deficiency is fairly rare in Western countries, but it can happen. If you take a long break from fresh produce , its possible to get scurvy which causes inflamed gums, skin spots, depression, and eventually death.

Its not common or likely if you have access to healthy food and produce, but its good to be mindful of your vitamin C intake all the same.

Don’t Miss: Which Vitamins Should I Take

Can You Be Allergic To Vitamin C

Technically, no. The isolated vitamin of ascorbic acid is an essential nutrient for human health and you would die without it. However you can have an allergic reaction to vitamin C tablets, face cream, serum, and drinks containing it. Since ascorbic acid is often made using corn, those with an allergy to that plant are at risk.

Allergy to vitamin C causes are unlikely to be from corn since that is a very rare allergy. Plus, the potential amount of allergens remaining residual protein matter from the plant would likely be in a concentration of only parts per million . If you are experiencing ascorbic acid intolerance its likely you are allergic to another ingredient in that supplement, fortified food, or skin cream.

On a related note, theres a strong likelihood the corn used is genetically modified. If you want non-GMO ascorbic acid, then make sure the packaging is labeled as such. Organic food-derived sources will always be non-GMO.

Vitamin C Megadoses Can Cause Gas And Diarrhea

This is completely true and we should be glad that this is the case.

When your body is saturated with as much vitamin C as you can handle, it dumps the excess in your colon for elimination. This results in diarrhea. Gas usually comes first to let us know that we are almost at that saturating point.

These vitamin C side effects make it easy to determine how much our bodies need and is the whole point behind the vitamin C flush.

That Pesky Skin Rash May Be Caused By Excess Vitamin B3

At first glance, vitamin B3 looks like a safe choice because it’s water-soluble . After all, how could something that dissolves in water build up in the body? Wouldn’t urinating take care of excess amounts of it? Although that’s true, the body still has to process it, and while it’s making its way from your stomach to your kidneys, vitamin B3 can cause some side effects. This is why it’s important to avoid exceeding 35 milligrams of the vitamin per day .

According to the Medline Plus, high intakes of B3 can cause skin rashes, elevated amounts of blood sugar, liver damage, and peptic ulcers, which can occur either in the stomach or the intestines. Even when it is used to treat high cholesterol, B3 can cause discomfort to the face, neck, arms, or upper chest. Specifically, you may experience tingling, itchiness, redness, or a warm sensation referred to as “flushing.”

If you’re looking for non-supplement ways to get vitamin B3, though, fish, poultry, lean meats, eggs, and milk are all great sources. Outside of animal-based products, B3 is also found in peanuts, legumes, and rice, according to Medline Plus.

by Dr Sam Ooi | Apr 21, 2020 | Vitamin C

Vitamin C can also help to slow down skin aging and lower cholesterol levels it can enhance our iron absorption and reduce the risk of gout while a deficiency can cause gingivitis and easy bruising.

Making sure of our levels of Vitamin C is something we need to monitor, to help us maintain good health, especially with our fast approaching flu season and the current global COVID-19 pandemic.

Vitamin C can be found in an abundant number of fruits and vegetables, including citrus fruit, broccoli, kiwi fruit, tomato, strawberry, and pineapple, just to name a few. Many of us also take vitamin supplements, sometimes in the form of chewable Vitamin C tablets.

We all agree that Vitamin C is essential for good health, but we also need to be aware of some possible side effects that it may cause. We need to monitor how much Vitamin C we have every day and how we get it.

The recommended daily amount for adults is 65 to 90 milligrams with a maximum of 2000 mg per day. Vitamin C is also known as ascorbic acid.

Yes A Vitamin C Overdose Is A Real Thing

Get more Spoon in your feed.Get Healthier Delivered

It’s that time of year. Your professor cancels class, your roommate is coughing nonstop, and the kid next to you in the library has a mound of used tissues piling up uncomfortably close to your laptop. You wash your hands and disinfect the doorknobs, but sometimes getting sick is just inevitable.

This is why when I felt that familiar feeling of the beginning of sickness, I decided that a healthy dose of vitamin C might help. Thus, my vitamin C bender day began. I started with an Emergen-C packet, followed by a glass of OJ at brunch, a green juice for a late afternoon treat, an immune booster tablet with dinner, and a smoothie for dessert. By my calculations, I had about 2,000% of my daily value of vitamin C.

However, after lying in bed for over two hours, I realized that I hadn’t yet fallen asleep. I tried deep breathing and lavender oil , but after another restless hour, I knew sleep just wasn’t in the cards. Coming from someone who can fall into REM sleep in an airport, I knew this bout of insomnia wasn’t normal.

In a 4:30 am haze, I googled “is too much vitamin C bad?” I browsed web page after web page detailing the various symptoms of consuming too much vitamin C. Sure enough, insomnia was listed as one of the many side effects.

You Could Suffer From Digestive Problems

Another likely symptom you’ll experience if you consume too much vitamin C is digestive distress. While you won’t get this issue from eating too many vitamin C├órich foods, overdosing on the supplement is likely to cause diarrhea, nausea, and sometimes acid reflux.

To avoid an upset stomach, you shouldn’t take more than 2,000 milligrams of vitamin C supplements at once, as that’s been identified as the tolerable upper limit per day.

Overloading On Vitamin C

Can Taking Too Much Vitamin C Hurt Your Body?

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.
