What is Vitamin C?

Vitamin C, known in the scientific community as ascorbic acid, is a water-soluble vitamin needed for many important functions and is essential for overall health.

It’s naturally found in many fruits and vegetables and helps support immune function, skin health, and reduces the risk of several chronic diseases.

Your body can’t make this vitamin on its own, so it’s important to get enough of it through the foods you eat and any needed additional supplementation.

People who are at risk of having low vitamin C include:

  • Individuals who smoke.
  • People who consume excessive amounts of alcohol.
  • Those who don’t eat a variety of foods, especially fruits and vegetables.
  • People with digestive conditions that cause poor nutrition absorption.

Health benefits of vitamin C supplements

Read on to learn several ways vitamin C can benefit your overall health.

Boosting the immune system

Your immune system is made up of a collection of cells and organs that work together to help fight off infection and sickness.

Vitamin C bolsters the immune system by supporting the production and function of white blood cells, some of the primary cells for fighting infection.

While experts have more to learn about the exact ways vitamin C assists, research shows that many cells in the immune system store up vitamin C in large amounts, demonstrating its importance for defending against infection.

Antioxidant properties and role in fighting free radicals

Vitamin C is a strong antioxidant that helps protect cells against free radical damage. Free radicals are unstable atoms that can cause damage to your cells. Over time, enough damage can lead to chronic illnesses, inflammation, and aging.

Researchers have discovered that vitamin C plays a role in protecting the cells from damage by neutralizing free radicals.

Supporting collagen production for skin health

Vitamin C is essential for healthy and glowing skin and can also aid in managing acne, primarily due to its important role in producing collagen. Collagen is a protein that provides structure and elasticity to the skin.

An example of vitamin C’s importance is scurvy, a condition characterized by gum disease, brittle bones, and skin wounds that used to be seen in sailors who were away at sea for longer periods of time.

The discovery that vitamin C deficiency caused scurvy was significant and led to the cure of eating citrus fruits.

Vitamin C is also beneficial in wound healing as it can accelerate the repair process of damaged skin by enhancing new tissue growth.

Potential role in reducing the risk of chronic diseases

Vitamin C’s role in potentially reducing the risk of chronic diseases ties into its ability to protect the body from free radicals which reduces inflammation and oxidative stress. Both of which are key factors in the development of chronic diseases.

Studies suggest that vitamin C may help lower the risk of cardiovascular disease by increasing blood flow through vasodilation (widening of blood vessels).

While the research is still mixed, several studies suggest that taking vitamin C supplements may help reduce the risk of age-related macular degeneration and cataracts, two of the main conditions that cause blindness.

Natural sources of vitamin C

The best way to get your vitamin C is through your diet. Fruits and vegetables are great sources of vitamin C, with citrus fruits at the top of the list.

While vitamin C is not naturally found in grains, some cereals are fortified with it, meaning the manufacturer adds vitamin C to enhance the nutritional value.

Here is a list of the top ten natural sources of vitamin C in order from highest to lowest:

  • Red peppers
  • Orange juice
  • Oranges
  • Grapefruit juice
  • Kiwis
  • Green peppers
  • Broccoli
  • Brussels sprouts
  • Grapefruit

Potential side effects and precautions when taking vitamin C

Doctors consider vitamin C to be safe. Generally, it does not cause side effects.

Some digestive complaints typically occur due to taking high doses of vitamin C. Symptoms may include:

  • Diarrhea.
  • Nausea.
  • Stomach cramps.

People taking certain medications, such as chemotherapy, radiation, or statins, should talk with their doctor before taking vitamin C because there can be interactions.

In general, it’s best to talk with your doctor before taking any new supplements, especially if you have pre-existing health conditions or are taking medications.

How to incorporate vitamin C supplements into your routine

Incorporating vitamin C into your routine can be simple. The Dietary Guidelines for Americans 2020-2025 suggest trying to meet most of your nutritional needs through diet.

The Institute of Medicine recommends that males over the age of 19 get 90 mg of vitamin C each day, and females get 75 mg.

If you smoke, you need an additional 35 mg of vitamin C each day, and people with particular circumstances such as pregnancy or lactation may need more vitamin C.

Eat several types of fruits and vegetables throughout the day to get vitamin C. Certain cooking methods, such as boiling, can decrease the vitamin C content, so try steaming your vegetables instead.

There’s no specific way you need to take your vitamin C supplement. Choose a time of day that works best for you and that you can be consistent with. If the vitamin tends to upset your stomach, try taking it with food rather than on an empty stomach.

Talk with your primary medical provider or registered dietitian for personalized advice on the best amount of vitamin C for you.

Best vitamin C supplement — conclusion

Vitamin C is an essential nutrient your body needs to function properly. It is especially important for supporting your immune system and skin health and possibly reducing your risk of chronic illnesses such as heart disease.

With so many vitamin C supplements available, it can be difficult to decide what is the best vitamin C supplement.

When looking for one, important considerations include the manufacturing process, the company's ingredients, third-party testing, and making sure the supplement fits your dietary preferences or needs.

Vitamin C doesn’t typically cause side effects, but if you take a large dose, you may feel some digestive discomfort or have diarrhea.

Talk with your doctor if you have further questions about taking vitamin C and if it’s right for you.
