Should I Take More Vitamin C When Im Sick

vitamin c requirement per day

Many people pop vitamin C pills when they feel a cold coming on. Though vitamin C helps the immune system, it does very little for a cold.

A study from the Australian National University found that vitamin C supplements did not prevent colds at all. Supplementation, in a few cases, helped people get over the cold a little bit faster since about 8 percent of participants had one less day of sickness due to vitamin C.

If you want to play it safe and add more vitamin C when youre sick, its still best to do it through food. Add more citrus or greens. Even if the vitamin C doesnt make a difference, the healthy food will help you feel better.

What Evidence Is There To Support Taking Vitamin C For Covid

There have been hundreds of studies investigating vitamin C, many of which have conflicting results. One of the biggest problems with vitamin C studies is that most do not measure vitamin C concentrations before or after supplementation. Supplementation is unlikely to show an effect in people whose vitamin C levels are already high.

COVID-19 is a new disease, and we are still learning about it. But several studies in other infections or conditions suggest it may be beneficial in certain groups of people, particularly those already deficient in vitamin C who develop COVID-19. Currently, at least two trials are underway specifically investigating the use of vitamin C to treat severe COVID-19, one in New York and one in China.

Beneficial effects of vitamin C supplementation have been reported for

  • Elderly people with acute respiratory infections
  • Recurrent acute respiratory distress syndrome
  • Reducing the severity and duration of the common cold
  • Reducing the length of hospital stay and symptoms in elderly patients with pneumonia
  • Reducing the duration of mechanical ventilation in people in ICU
  • Preventing the common cold in people who are vitamin C deficient
  • Preventing the incidence of pneumonia in people who are vitamin C deficient.
  • Studies have shown that excretion of vitamin C is decreased during infections, such as the common cold, suggesting that more is utilized during times of need.

The Recommended Dietary Allowance

The recommended dietary allowance for vitamin C is based on the amount of vitamin C intake necessary to maintain neutrophil vitamin C concentration with minimal urinary excretion of vitamin C and is proposed to provide sufficient antioxidant protection . The recommended intake for smokers is 35 mg/day higher than for nonsmokers, because smokers are under increased oxidative stress from the toxins in cigarette smoke and generally have lower blood concentrations of vitamin C .

Can You Have Too Much Vitamin C

The Future Of Vitamin C: Liposomal Vitamin C Healthy ...

The reason we need to top up our vitamin C regularly is that the nutrient is water soluble: in other words, our bodies cant store it and it gets flushed out when you urinate.

Because of this, its quite difficult to have too much vitamin C in your diet even with lots of fruit and veg and a moderate supplement. Potential problems usually only arise when youre taking very high vitamin C supplements of more than 1,000mg every day. This can cause stomach pain, diarrhoea, and flatulence.

You should also be careful if you suffer from haemochromatosis, a condition where your body retains too much iron in your blood. Thats because vitamin C can increase iron absorption.

The recommended dose of vitamin C should be doubled, according to a recent study.

Scientists behind the claim have described the methods behind the 1944 study that continues to inform current day levels as shocking.

At present, the NHS and World Health Organisation recommend a daily intake of the vitamin of 40mg and 45mg respectively.

However, academics behind a new study published in the American Journal of Clinical Nutrition have said that the research conducted by The Sorby Research Institute was to assess the nutrition levels of Britons during World War II when food was in short supply.

At this time, the aim was to avoid scurvy, rather than maximising health, they claim.

What Is And How Much Vitamin C Per Day – Functions, Benefits Of, Foods High In Vitamin C

During the autumn and winter, you need to get vitamin D from your diet because the sun is not strong enough for the body to make vitamin D.

But since it’s difficult for people to get enough vitamin D from food alone, everyone should consider taking a daily supplement containing 10 micrograms of vitamin D during the autumn and winter.

Between late March/early April to the end of September, most people can make all the vitamin D they need through sunlight on their skin and from a balanced diet.

You may choose not to take a vitamin D supplement during these months.

How Much Vitamin C Is Enough

Most of the studies Moyad and his colleagues examined used 500 daily milligrams of vitamin C to achieve health results. That’s much higher than the RDA of 75-90 milligrams a day for adults. So unless you can eat plenty of fruits and vegetables, you may need to take a dietary supplement of vitamin C to gain all the benefits, Moyad says. He suggests taking 500 milligrams a day, in addition to eating five servings of fruits and vegetables.

“It is just not practical for most people to consume the required servings of fruits and vegetables needed on a consistent basis, whereas taking a once-daily supplement is safe, effective, and easy to do,” Moyad says. He also notes that only 10% to 20% of adults get the recommended nine servings of fruits and vegetables daily.

Moyad says there is no real downside to taking a 500-milligram supplement, except that some types may irritate the stomach. That’s why he recommends taking a non-acidic, buffered form of the vitamin. “The safe upper limit for vitamin C is 2,000 milligrams a day, and there is a great track record with strong evidence that taking 500 milligrams daily is safe,” he says.

Still, American Dietetic Association spokeswoman Dee Sandquist, RD, suggests doing your best to work more fruits and vegetables into your diet before taking supplements.

Recommended Sodium Intake For Older Adults

Sodium is another important mineral. In most Americans diets, sodium primarily comes from salt . Whenever you add salt to your food, you’re adding sodium. But the Dietary Guidelines shows that most of the sodium we eat doesnt come from our saltshakers its added to many foods during processing or preparation. We all need some sodium, but too much over time can lead to high blood pressure, which can raise your risk of having a heart attack or stroke.

How much sodium is okay? People 51 and older should reduce their sodium intake to 2,300 mg each day. That is about one teaspoon of salt and includes sodium added during manufacturing or cooking as well as at the table when eating. If you have high blood pressure or prehypertension, limiting sodium intake to 1,500 mg per day, about 2/3 teaspoon of salt, may be helpful. Preparing your own meals at home without using a lot of processed foods or salt will allow you to control how much sodium you get. Try using less salt when cooking, and dont add salt before you take the first bite. If you make this change slowly, you will get used to the difference in taste. Also look for grocery products marked low sodium, unsalted, no salt added, sodium free, or salt free. Also check the Nutrition Facts Label to see how much sodium is in a serving.

Does Vitamin C Lower Chronic Disease Incidence Mortality Or Both

Cardiovascular disease

Coronary artery disease and stroke are the leading causes of morbidity and mortality in the United States and other westernized populations. Cardiovascular disease is responsible for nearly one million deaths every year in the United States alone, at the cost of > $15 billion in health care and lost productivity . Major risk factors associated with cardiovascular disease are age, male sex, smoking, hypercholesterolemia, hypertension, family history, obesity, and physical inactivity . Many epidemiologic studies have shown inverse associations between antioxidant intake, particularly vitamin E, and cardiovascular disease . Over the past 15 y, several prospective cohort studies have been published on the association between vitamin C intake and the risk of cardiovascular disease . Some of these were reviewed previously by Enstrom and Gey , as well as by others . Because the purpose of this review is to propose an RDA for vitamin C based on chronic disease incidence, only studies that stated actual amounts of vitamin C intake are considered further here.

Good Sources Of Vitamin D

How much Vitamin C do you need each day?

From about late March/early April to the end of September, most people should be able to make all the vitamin D they need from sunlight.

The body creates vitamin D from direct sunlight on the skin when outdoors.

But between October and early March we do not make enough vitamin D from sunlight. Read more about vitamin D and sunlight.

Vitamin D is also found in a small number of foods.

  • fortified foods such as some fat spreads and breakfast cereals

Another source of vitamin D is dietary supplements.

In the UK, cows’ milk is generally not a good source of vitamin D because it is not fortified, as it is in some other countries.

What Is Vitamin D

Vitamin D is a fat-soluble vitamin that acts as a steroid hormone in the body.

There are two types of vitamin D in the diet:

Vitamin D2 : is found in some mushrooms.

Vitamin D3 : is found in oily fish, fish liver oil, and egg yolks.

D3 is more potent in these two types and raises blood levels of vitamin D by almost twice as much as D2.

A large amount of vitamin D can also be produced on your skin when exposed to UV rays from the sun. Any excess vitamin D is stored in your body fat for later use.

Every cell in your body can absorb vitamin D. This vitamin is involved in many processes, including bone health, immune function, and cancer prevention.

Whats The Recommended Daily Intake Of Vitamin C

The recommended daily intake of vitamin C is 75 90 mg. Its 70 mg for women and 90 mg for men.

Moreover, smokers need more vitamin C per day. They need additionally 35 mg of vitamin C a day, as smokers have increased oxidative stress. A study suggested that drinking orange juice can increase plasma concentrations of vitamin C in humans. Smokers can benefit the most.

Additionally, women in pregnancy require at least 85 mg of vitamin C. Furthermore, women in lactation require at least 120 mg. Always consult your health care provider before taking any supplements.

So, the maximum recommended vitamin C dose of 120 mg is way less than the dose of a 1,000 mg pill. Is a daily consumption of 1,000 mg of vitamin C safe? Pretty safe actually

    Impair The Effectiveness Of Niacin

    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.

    Should I Take A Vitamin C Supplement

    If you are eating a balanced diet, most likely you do not need to take a vitamin C supplement, says McGowan. Vitamin C is water-soluble meaning the body utilizes it but doesnt store it. For most healthy individuals, the body can only hold and use about 200 to 250 mg of vitamin C a day, and any excess is lost through urine, explains McGowan.

    Despite this, you can overconsume vitamin C. This is most likely to occur with supplement use, so make sure your daily intake falls below the tolerable upper limit , or the maximum daily intake thats unlikely to result in negative health effects. That amount for a 1- to 3-year-old child is 400 mg, while its 650 mg for a 4- to 8-year-old child, 1,200 for a 9- to 12-year-old child, and 1,800 mg for a 14- to 18-year-old teenager. The UL for an adult is 2,000 mg. Keep in mind that if you take a multivitamin, youre getting vitamin C there, too dont forget to add that amount to your total supplemental intake.
