Large Doses Can Be Harmful Even Without Symptoms Of Toxicity

Large doses of vitamin D can be harmful, even though there may not be immediate symptoms of toxicity.

Vitamin D is very unlikely to cause severe symptoms of toxicity right away, and symptoms may take months or years to show up.

This is one reason why vitamin D toxicity is so difficult to detect.

There have been reports of people taking very large doses of vitamin D for months without symptoms, yet blood tests revealed severe hypercalcemia and symptoms of kidney failure .

The harmful effects of vitamin D are very complex. High doses of vitamin D can cause hypercalcemia without toxicity symptoms, but can also cause toxicity symptoms without hypercalcemia .

To be safe, do not exceed the 4,000 IU upper limit without consulting a doctor or dietitian.

What Is Vitamin C

Vitamin C is an important vitamin and antioxidant that the body uses to keep you strong and healthy. Vitamin C is used in the maintenance of bones, muscle, and blood vessels. Vitamin C also assists in the formation of collagen and helps the body absorb iron.

Vitamin C is found naturally in vegetables and fruits, especially oranges and other citrus fruits. This key vitamin is also available as a natural dietary supplement in the form of vitamin C pills and vitamin C chewable tablets.

Like vitamins, minerals also help your body function. Minerals are elements that our bodies need to function that can be found on the earth and in foods.

How Much Vitamin C To Slay Your Sniffles

Can Vitamin C Cause Kidney Stones? How Much Vitamin C Per Day Should You Take?

Common Cold, Virus

Vitamin C is best known for its ability to fight viruses especially the common cold.

Of course, some people will tell you vitamin Cs cold-fighting abilities are a myth. But, the truth is, its cold-fighting reputation is warranted

Studies show that if you take vitamin C before catching a cold it can reduce the severity of your symptoms. And, if you take it after catching a cold, it can shorten the duration of your cold. But heres the catch

Most clinical trials show that vitamin C only reduces the duration of your cold by a mere 10 percent. That means, if you have a cold that would typically last 10 days, vitamin C can knock the time you spend sneezing and sniffling down to nine days.

Now, one less day spent feeling sick and miserable is worth the minimal effort required to take a daily vitamin C pill. But it does make you wonder whether vitamin C is the miracle cure for colds that weve hoped for all these years

I, for one, know there have been times when Ive taken vitamin C at the first signs of a cold and its gone in a day or two max. And Im sure youve probably had experiences like this too. So why do these anecdotal experiences defy the clinical evidence?

Well, it may be due to dosage.

Can You Take Too Much Vitamin C

The tolerable upper intake for adults is 2 grams of Vitamin C consuming more than that can result in diarrhea and other unpleasant GI disturbances, says Greaves. She admits that severe side effects from too much ascorbic acid are very rare, but you may experience some discomfort if you take too much. Its pretty much impossible to have a vitamin C overdose, but lets not test that out.

The real problem with taking more vitamin C than you need is that it all goes to waste. Up to 100 mg a day of vitamin C will get almost completely absorbed, says Francesco-Maria Serino, MD, PhD. Above 100 mg a day and the fraction of vitamin C absorbed is progressively smaller. If you take more than 1 gram of vitamin C per day, less than 50% is actually absorbed and its eliminated by the kidneys.

That literally means that a 500 mg vitamin C supplement mostly gets peed down the drain.

How Much Vitamin C Do You Need In A Day

Since the human body does not produce or store vitamin C, we must consume it regularly through fruits and veggies. It supports a large number of body processes related to growth and repair. Vitamin C works with protein to make skin, tendons, and blood vessels. It helps heal wounds and repair cartilage, bones, and teeth. Adequate amounts also result in less bruising, faster healing, and healthier gums and teeth. Vitamin C helps increase iron absorption from plant-based foods. An important antioxidant, vitamin C also plays a role in immune function. So, yes, it is vital to our health, but megadosing is not the answer.

So, how much vitamin C is enough? The RDA primarily depends on age and gender. For example,

  • Adult men, 19 and older: 90 mg/day
  • Adult women, 19 and older: 75 mg/day
  • Adult pregnant women: 85 mg/day
  • Adult breastfeeding women: 120 mg/day
  • Adult smokers need an additional 35 mg/day because of smoke’s oxidative effects.

The tolerable upper limit for vitamin C is 2,000 mg /day. Megadosing on vitamin C supplements above the UL may cause diarrhea, nausea, vomiting, heartburn, abdominal bloating and cramping, headache, insomnia, and kidney stones. Also, prolonged use of large doses of vitamin C may increase the nutrients’s metabolism, causing losses. Once vitamin C decreases, you could develop rebound scurvy. As is the case with most nutrients, it is best to get enough vitamin C, but not in excessive amounts.

How Much Is Too Much

According to the dietary guidelines, the max amount of vitamin C that is safe to take each day is 1800 milligrams. Taking in more can cause stomach upset, nausea and diarrhea, which typically resolves quickly once the usage is discontinued. Some data suggests excessive intakes for long periods of time may be linked to kidney stones in people with existing kidney issues.

This may seem like an unattainable amount , but whether its a fizzy drink mix or chewable tablet, the average cold prevention supplement contains 1000 milligrams per serving. Many of these products recommend taking a dose multiple times a day, quickly exceeding the 1800 milligrams recommendation and this is before you eat any vitamin C rich foods. It is also important to point out many of these products also include other vitamins and minerals, some of which may carry their own separate risks for toxicity or interactions with medications, so check labels carefully so you know what you are taking.

Why Do People Take Vitamin C

How Much Vitamin C Can I Take in a Day?

Studies have shown that vitamin C may reduce the odds of getting a cold, but only in specific groups in extreme circumstances, such as soldiers in subarctic environments, skiers, and marathon runners. Studies have not found solid evidence that vitamin C helps prevent or treat colds in average situations.

Vitamin C’s antioxidant benefits are also unclear. While some studies of vitamin C supplements have been promising, they have not found solid evidence that vitamin C supplements help with cancer, stroke, asthma, and many other diseases. Some evidence suggests that vitamin C may be helpful in people who have high cholesterol and in preventing cataracts, but more studies are needed to prove these effects.

Data on vitamin C and heart disease are mixed. Some studies show an association between low levels of vitamin C and heart disease risk, yet many studies have linked the use of vitamin C supplements with an increased risk of heart disease.

Studies have shown that dietary rather than supplemental sources of vitamin C are more effective in keeping blood pressure in check.

A substantial number of Americans may have low intake levels of vitamin C due to the inadequate intake of fruits and vegetables. The proven and effective use of vitamin C is for treating vitamin C deficiency and conditions that result from it, like scurvy.

Vitamin C also seems to help the body absorb the mineral iron.

Two small studies that used historic controls reported favorable clinical outcomes in patients with sepsis or severe pneumonia who received a combination of vitamin C, thiamine, and hydrocortisone.8,9 Subsequently, several randomized trials in which patients received vitamin C and thiamine to treat sepsis and septic shock showed that this combination conferred benefits for certain clinical parameters. However, no survival benefit was reported. Two trials observed reductions in organ dysfunction 10,11 or the duration of shock12 without an effect on clinical outcomes.

Understanding A Vitamin D Overdose

It is best to take Vitamin C in the raw form as heat and light can destroy the amount of vitamin in the particular food. Cooking Vitamin C rich food for a long time at a high temperature can break down the vitamin.

Stir-frying or blanching are the best ways to preserve the vitamin. Also, try to eat fruits that are ripe as they contain the maximum amount of Vitamin C.

Common Cold And Vitamin C Fact Or Futility

Controversy exists about vitamin C’s role with the common cold. Some research shows that vitamin C levels in the body decrease at the start of a cold and that increasing vitamin C intake might be beneficial. Other evidence shows that the body holds onto vitamin C due to increased demand and that extra vitamin C intake does not help combat a cold. Cold prevention using high-dose vitamin C supplements lacks evidence. With its weak antihistamine effects, vitamin C might make cold symptoms milder and shorten its duration.

Some researchers think that mild vitamin C deficiency may be more widespread than you think. Vitamin C deficiency can result in fatigue, anemia, bleeding gums, decreased ability to fight infection, increased bruising, nosebleeds, swollen and painful joints, and dry, splitting hair. After three to five months, sustained vitamin C deficiency can cause scurvy with symptoms of bleeding gums and loose teeth.
