What is ascorbic acid?

Ascorbic acid, better known as Vitamin C, is well known for its antioxidant and antibacterial properties. It also has powerful tissue repairing qualities, which make it able to effectively reverse scurvy (deficiency) and treat other diseases characterized by tissue damage.

What are the uses for ascorbic acid?

  • Scurvy
  • Vitamin C deficiency
  • Anti-ageing skincare
  • Bacterial infection
  • Common Cold

Ascorbic acid solution is a popular ingredient in skincare, particularly in people looking to reduce fine lines and wrinkles. People with vitamin C deficiency often take ascorbic acid tablets as an oral supplement.

What are the benefits of ascorbic acid?

Ascorbic acid – or any vitamin c – is beneficial because of its ability to promote the natural functions of the body. It helps wounds to heal quickly and fight infection, it keeps bones strong and it helps our immune systems fight off illness.

The easiest way to see the benefits of vitamin c is to look at the symptoms of vitamin c deficiency. These include recessed and bleeding gums, fatigue and weakness, sores on the skin and rash.

How does ascorbic acid work?

Ascorbic acid works by promoting and protecting collagen (the protein that keeps skin plump).

It is also an antioxidant, meaning it balances the levels of free radicals in our blood. Free radicals are atoms with an odd number of electrodes, which bounce around the body causing random chemical reactions that can lead to cancer or other conditions.

Ascorbic acid is also important in promoting iron absorption, so promotes healthy blood by increasing red blood cell production.

What is the recommended dosage for ascorbic acid?

Most clinical trials agree that it is preferable to avoid a vitamin c deficiency by consuming adequate amounts in the diet. Daily recommended doses of vitamin c are 45mg for children, 75mg for women and 90mg for men. Breastfeeding women should increase to 120mg.

For some, it is not possible to consume enough of the natural vitamin, so supplemental ascorbic acid might be recommended.

When taken orally, ascorbic acid should be taken in a dose no larger than 2000mg for adults (including breastfeeding adults) and 1800mg for adolescents.

The daily recommended doses for children are as follows:

  • 1-3 years: 15mg
  • 4-8 years: 25mg
  • 9-13 years: 45mg
  • 14-18years: 75mg (boys), 65mg (girls)
  • Pregnant or breastfeeding under 18 years: 115mg

Types of ascorbic acid

Ascorbic acid powder is the most common form of vitamin c in skincare, but it can also be taken orally in tablets for anyone with a deficiency.

The best type for you depends on your condition but, generally, skin conditions will require powder or a specialized product (such as serum or moisturizer) and other conditions will require tablet or oral solution.


What are the benefits of ascorbic acid?

Ascorbic acid has collagen-boosting and antioxidant properties. It also promotes iron absorption and good organ, skin and bone health.

What does ascorbic acid do for skin?

Ascorbic acid promotes the health and renewal of collagen, tightening and plumping the skin. In people with photodamaged skin, it has also been found to reduce wrinkles, roughness and discoloration in patients with photodamaged skin.

Is ascorbic acid bad for you?

Ascorbic acid is safe for human consumption, however some people might experience side effects such as nausea, heartburn and headaches. As with any supplement, make sure you do not exceed the recommended dose and consult with your doctor if you are concerned.

What is l ascorbic acid?

L-Ascorbic Acid is the same as ascorbic acid. The L- is often dropped for ease, but it refers to the molecular makeup of the substance. The formula for ascorbic acid is C₆H₈O₆.

What is ascorbic acid made from?

Ascorbic acid is made from vitamin C. It is found in high quantities in fruits – especially citrus – and vegetables. Some supplements, including ascorbic acid, are made synthetically.

Naturally occurring vitamin C might have higher bioavailability, making it easier to absorb than synthetic varieties. Speak to your pharmacist if you want to know how a specific brand of ascorbic acid is made.

Conditions ascorbic acid powder might help

Ascorbic acid for iron deficiency

Ascorbic acid interacts with iron to make it absorbed more efficiently. It is therefore recommended that those taking iron supplements also take ascorbic acid.

However, a study found that 200mg of vitamin c taken orally every 8 hours for 3 months had a slight but non-significant improvement on symptoms of anemia.

Ascorbic acid for Alzheimer's and Dementia

Ascorbic acid has been found to protect against Alzheimer's disease, as well as other age-related neurological diseases. While more research is needed to suggest causation, this study suggests that a dose of 400mg is beneficial.

Ascorbic acid for flu

Research suggests that ascorbic acid can reduce cold and flu symptoms by up to 85%. This study administered "megadoses" of 9000mg daily.

A subsequent meta-analysis found that while there were improvements in symptoms across many clinical trials, they were not worth the slight potential side effects of taking such high doses.

Ascorbic acid for high blood pressure

Ascorbic acid in plasma is associated with reduced blood pressure in those suffering from hypertension. A review of studies found that the antioxidant properties of vitamin c make an orally administered dose of 500mg (between 60 and 4000mg) a day beneficial.

Ascorbic acid for heart disease

Ascorbic acid might help reduce the likeliness of a person dying from heart disease, by allowing them to avoid vitamin c deficiency. A meta-analysis found that, while many studies suggested the relationship, there is not enough evidence for physicians to suggest this treatment yet.

The average recommended dose for reducing the impact of heart disease is 500mg a day taken orally.

Ascorbic acid for gout

Multiple studies indicate that ascorbic acid can help to reduce levels of uric acid in the blood. This is likely to help to reduce instances and severity of gout by reducing the chance of urate crystals from forming.

The average dose studied was 500mg a day, taken orally.

Ascorbic acid for scurvy (vitamin c deficiency)

One of the first uses for vitamin c was to relieve vitamin c deficient individuals from the effects of scurvy. Sailors on long voyages were likely to become vitamin c deficient, but it is also correlated to those with lower socioeconomic status.

Sailors would suck on citrus fruits to reduce their symptoms, but synthetic ascorbic acid is now used as a supplement. Typically, 300mg is given to children and 500-1000mg is given to adults.
