Most people can get adequate vitamin C in their diet by eating fruits and vegetables. However, some people take a vitamin C supplement due to dietary restrictions or a medical condition.

Vitamin C, or ascorbic acid, is a water-soluble vitamin and antioxidant that is essential for health. It helps the immune system, skin, and bones to function, and combats damage from free radicals, which are molecules that can adversely affect the body.

This article looks at who may benefit from taking vitamin C, how much people need to consume per day, and some of the best vitamin C supplements on the market.

According to the National Institutes of Health (NIH), vitamin C deficiency is rare in the United States. Although most people can get enough vitamin C from fruits and vegetables, others have difficulty getting enough vitamin C from their diet.

People who may be at risk for vitamin C deficiency include:

Anyone concerned that they have a deficiency can ask a doctor for blood tests to see which nutrients they need. A long-term deficiency in vitamin C can lead to scurvy.

In addition to those who have a vitamin C deficiency, some other people may also benefit from consuming more of this nutrient. For example, some evidence suggests vitamin C can reduce the severity and duration of the common cold.

According to the NIH, there is no conclusive evidence that vitamin C has an impact on COVID-19.

According to the NIH, the recommended intake of vitamin C is between 7590 milligrams (mg) per day.

Typically, the small intestine absorbs up to 100 mg of vitamin C from food per day. Once the cells have become saturated with vitamin C, they cannot absorb any more.

However, some people believe that taking very large doses of vitamin C, or mega-dosing is beneficial. This may stem from a 1976 paper that indicated that high-dose vitamin C could prolong the life of people with terminal cancer.

However, more recent studies have failed to repeat this result.

Vitamin C doses of over 2,000 mg per day may cause side effects, such as:

People with particular health conditions or who take certain medications may also need to avoid vitamin C supplements. Conditions include:

Vitamin C may also interact with chemotherapy treatment.

The Food and Drug Administration (FDA) do not approve Vitamin C products. It is important to discuss taking any new supplement with a doctor.

There are several forms of vitamin C. In supplements, vitamin C usually comes in the form of ascorbic acid. However, some supplements contain other forms, such as sodium ascorbate, calcium ascorbate, or ascorbic acid with bioflavonoids.

According to the NIH, all forms of vitamin C are similarly beneficial.

There are various ways to take vitamin C, including:

Some people may prefer the convenience of swallowing tablets, while others may prefer a powder they can mix into drinks.

People with problems absorbing nutrients may prefer a sublingual supplement, as the body absorbs these in the mouth, rather than in the intestines.

There are many vitamin products on the market, and because they are not FDA-approved, they may vary significantly in purity, ingredients, and dosage. Always buy vitamin C from a reputable company and ensure the products undergo third-party testing.
