Importance of Vitamin C

Vitamin C, also known as ascorbic acid, is an essential nutrient that the body needs to function properly. It is a water-soluble vitamin, which means that the body cannot store it and must be replenished on a daily basis through diet or supplements.

Immune Function

One of the most well-known functions of vitamin C is its role in supporting the immune system. Vitamin C helps to stimulate the production of white blood cells, which are responsible for fighting off infections and diseases. It also helps to protect these cells from damage caused by harmful molecules known as free radicals.

According to a study published in the journal Nutrients, vitamin C can also help to reduce the severity and duration of colds and other respiratory infections.

Collagen Synthesis

Vitamin C is also essential for the production of collagen, a protein that is found in the skin, bones, and connective tissues throughout the body. Collagen provides structural support to these tissues and helps to keep them strong and healthy.

Without enough vitamin C, the body is unable to produce collagen, which can lead to a range of health problems, including joint pain, skin damage, and weakened bones.

Antioxidant Properties

Finally, vitamin C is a powerful antioxidant, which means that it helps to protect the body from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and contribute to the development of chronic diseases, such as cancer, heart disease, and Alzheimer’s disease.

By neutralizing these harmful molecules, vitamin C helps to protect the body from oxidative stress and reduce the risk of developing these conditions.

In summary, vitamin C is a crucial nutrient that plays a variety of important roles in the body. From supporting the immune system to promoting collagen production and protecting against oxidative stress, it is essential for overall health and wellbeing.

Daily Vitamin C Requirements

Recommended Dietary Allowance

Vitamin C is an essential nutrient required by the body for the growth and repair of tissues. It is also an antioxidant that helps to protect cells from damage caused by free radicals. The Recommended Dietary Allowance (RDA) for vitamin C varies depending on age, sex, and other factors.

According to the National Institutes of Health (NIH), the RDA for vitamin C for adult men is 90 milligrams (mg) per day, while adult women need 75 mg per day. Pregnant women require 85 mg per day, and lactating women need 120 mg per day. Smokers require an additional 35 mg per day due to the increased oxidative stress caused by smoking.

Factors Affecting Vitamin C Needs
