What Is Vitamin C And What Does It Do

How To Take It

Vitamin C – What is it & What is it Good For?

The best way to take vitamin C supplements is 2 – 3 times per day, with meals, depending on the dosage. Some studies suggest that adults should take 250 – 500 mg twice a day for any benefit. Talk to your doctor before taking more than 1,000 mg of vitamin C on a daily basis and before giving vitamin C to a child.

Daily intake of dietary vitamin C is listed below.


  • Men over 18 years: 90 mg
  • Women over 18 years: 75 mg
  • Pregnant women 14 – 18 years: 80 mg
  • Pregnant women over 18 years: 85 mg
  • Breastfeeding women 14 – 18 years: 115 mg
  • Breastfeeding women over 18 years: 120 mg

Because smoking depletes vitamin C, people who smoke may need an additional 35 mg per day.

The dose recommended to prevent or treat many of the conditions mentioned in the Uses section is often 500 – 1,000 mg per day.

How Common Is Vitamin C Deficiency

Scurvy due to vitamin C deficiency is rare in the UK.

There are certain groups of people who are more at risk of vitamin C deficiency. They include:

  • People dependent on drugs and/or alcohol who may not have a healthy, balanced diet.
  • People who go on very restrictive diets.
  • People living on a low income who tend not to buy foods with a high vitamin C content.
  • People with a medical condition that affects the body’s ability to digest and absorb food, such as Crohn’s disease and ulcerative colitis.
  • Older people who may eat a less varied diet.
  • Smokers. Smoking affects the absorption of vitamin C from foods and also vitamin C is used up in the body more quickly in those who smoke.
  • Pregnant and breastfeeding women because they need higher amounts of vitamin C.

Potential Side Effects And Risks

Although irritation is unlikely, you should always do a patch test prior to full application. This is the only way to determine how your skin will react to the serum.

If your skin is especially sensitive, avoid products with L-ascorbic acid. Products with magnesium ascorbyl phosphate may be less likely to cause irritation.

Serum stability is affected by two things product formulation and packaging.

The following vitamin C derivatives are designed to retain potency for longer:

  • L-ascorbic acid
  • ascorbyl palmitate
  • magnesium ascorbyl phosphate

You should also ensure that the product has a water-free formulation. And the bottle should be opaque and airtight.

How To Know If Your Child Has A Vitamin C Deficiency

The good news: Vitamin C deficiency is quite rare in the United States.

Vitamin C deficiency is very seldom seen in children and adults in developed countries, unless they have severe intestinal malabsorption or poor eating habits that avoid sources of vitamin C, says Dr. Radhakrishnan.

Diagnosing vitamin C deficiency requires special blood tests. But the main condition caused by deficiency of vitamin C is scurvy, which is very rare. Scurvy was described by the ancient Egyptians and in pirate stories, as it was a leading cause of death during long ship voyages in the industrial revolution era.

People with scurvy may have small brown spots on the skin, roughening of the skin, thickening of the gums and bleeding from the mucous membranes. They also may have a feeling of weakness or discomfort, emotional changes, poor wound healing, bone pain, and in late stages, jaundice, nerve involvement and convulsions.

Might Lighten Dark Spots

Why is Vitamin C So Good For Skin

Vitamin C-based skin care products may lighten patches that are darker than the rest of your skin, called hyperpigmentation. In one study, vitamin C applied to the skin for 16 weeks significantly cut down on these spots. But experts say it will take more research to confirm how well vitamin C creams work.

How To Choose A Supplement

The FDA licenses various supplements. However, some of them are not held to the same safety standards as pharmaceuticals. Therefore, if you wish to take a vitamin C supplement, you should ensure that its a high-quality one bought from reliable sources. You should also have a clear idea about the dosage and choose supplements that have been tested by reputable companies. It is best to consult your doctor before you opt for a vitamin C or a multivitamin supplement.

Vitamin C is an important nutrient that keeps the immune system functioning properly. Most adults need 90 mg of vitamin C per day. To get enough of it in your diet, ensure you eat a variety of vegetables and fruits. Fruits rich in vitamin C include cantaloupe, orange, grapefruit, and other citrus fruits, kiwis, mangos, papayas, pineapples, strawberries, raspberries, blueberries, etc. Broccoli, Brussels sprouts, cauliflowers, certain peppers. spinach, tomatoes, and potatoes are some vegetables rich in vitamin C.

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.

How Else Does Vitamin C Benefit The Skin

Amazingly, vitamin C’s skin-saving benefits aren’t limited to its antioxidant status. It has plenty of other skin-healing properties that make it worthy of a permanent place in your medicine cabinet. For one, when vitamin C is used topically, because it’s highly acidic, “the skin is triggered to heal itself by accelerating the production of collagen and elastin,” explains New York City-based dermatologist Howard Sobel. Remember: Collagen and elastin are both naturally occurring protein fibers that help keep skin plump and firm. So, in helping to promote collagen production, topical vitamin C can help prevent premature aging of the skin.

Another cool thing about the ingredient: It contains a property that inhibits your skin’s melanin production, which is what causes skin discoloration like dark spots and hyperpigmentation, Wexler explains. With continued topical use, vitamin C can help prevent dark spots from forming in the first place.

“It’s a superior brightening agent that works to fade brown spots without altering normal skin pigmentation,” Sobel adds.

Can A Vitamin C Supplement Really Keep You From Getting Sick

Despite it’s popularity as a remedy for the common cold, there’s actually no evidence to suggest that a large dose of vitamin C can actually prevent one or any other type of illness, for that matter.

And while you may have heard that a large dose of vitamin C can slightly reduce the duration of a cold, this only applies if you take that large dose every singleday of the year even when you’re not sick. This means that if you rip that vitamin C packet open after your symptoms begin, there’s no evidence to suggest it’ll actually shorten the length of your cold.

As it turns out, boosting your immune system is more complicated than just downing a packet or a pill. And while vitamin C does play an important role in supporting your immune system, it doesn’t take megadoses like the ones found in supplements which often contain 1667% more vitamin C than you actually need every day.

Vitamin C And Cancer Therapy

Also, the authors of a suggest that vitamin C might work well alongside other treatments to benefit people with cancer.

The note that some alternative therapists already use intravenous vitamin C when treating cancer, fatigue, and infections. However, they note that more research is necessary.

Intravenous vitamin C

2,000 mg per day .

Taking too much vitamin C is unlikely to cause any significant problems, but if a person consumes more than 1,000 mg of vitamin C per day, they will not absorb it all. This may lead to diarrhea and gastrointestinal discomfort.

People are unlikely to consume too much through their diet, and their bodies cannot store it. However, having a high intake through supplements may result in kidney stones.

This may also increase the risk of cardiovascular problems in females after menopause, but there is not enough evidence to confirm this.

Skin cell turnover is the process by which dead cells are shed from the skins top layer and new, fresh cells rise to the surface. One feature of healthy skin is its ability to efficiently turn over – a process that slows with age. With its acidic nature, Vitamin C is helpful in sloughing away dead and damaged skin cells, thereby speeding up the skins natural turnover process. This not only smooths skin texture, but also reduces dullness and minimizes the look of dark spots and hyperpigmentation.
