Vitamin C for Immune Health

BARRIER FUNCTION

The body's first line of defense, the physical barrier created by the skin, relies on vitamin C. Vitamin C is necessary for the production of collagen, an important type of connective tissue.** Collagen creates the structural framework of the skin to promote skin integrity, helping to effectively keep unwanted substances from entering the body.

ANTIOXIDANT HEALTH

Vitamin C's important role in immune health does not stop at the surface.** During the initial stages of the immune response, white blood cells of the innate immune system start the inflammatory response as one means of dealing with unwelcomed visitors. In a state of inflammation, an abundance of free radicals can be produced.

Free radicals are unstable compounds that can interfere with a normal cell's ability to function optimally. Free radicals cannot differentiate between your own healthy cells and the target of your immune system so they can end up damaging your own cells. Vitamin C is a powerful antioxidant that helps to fight free radicals.** It also helps to regenerate other antioxidants like vitamin E to their active state to maintain antioxidant support.**

WHITE BLOOD CELL SUPPORT

In addition to supporting skin integrity and antioxidant health, vitamin C is essential for the optimal functioning of white blood cells.** During an immune response, white blood cells go through a process of rapid division and multiplication. Vitamin C supports the production of the important B and T cells of the adaptive immune response.** It also helps special types of cells of the innate immune system called phagocytes do their job, engulfing unwanted compounds.**

Why Supplement with Vitamin C?

The Recommended Dietary Allowance (RDA) for adults is between 75-90 mg per day depending on gender, but some experts recommend a daily intake of at least 200 mg/day for healthy individuals.⁹

Unlike most other animals, humans cannot synthesize their own vitamin C so it must be obtained from dietary sources. As a water soluble vitamin, vitamin C dissolves easily in water but cannot be readily store in the body. This means adequate amounts of vitamin C should be consumed every day.

Vitamin C is found in foods such as citrus fruits, strawberries, cantaloupes, raw vegetables and potatoes. Unfortunately, in today's busy world, many of us do not consume as many fruits and vegetables as we should. National survey data indicates Americans are not meeting the recommendations for daily fruit and vegetable intake, resulting in a significant prevalence of about 40% of Americans with inadequate dietary intake of vitamin C.⁸ Furthermore, vitamin C is sensitive to heat so boiling and other cooking methods can deplete the natural vitamin C content of foods.

Daily intake of 200 mg supports respiratory health.^** Note that while this amount provides adequate support for most healthy individuals, actively multiplying and dividing white blood cells may have even higher requirements of vitamin C.^**

What is the Immune System?

Every day, your body is bombarded by foreign substances from the outside world. Credit card pin pads, bathroom faucets, cell phones, literally everything you touch is covered in tiny microorganisms. Not all microorganisms are bad, in fact there are trillions of bacteria found in and on the human body which cause no harm, or in some cases are even beneficial to human health.

However, there are also less favorable microorganisms found in the environment. The main function of your immune system is to protect you from external threats and keep you healthy.

Think of your immune system as your body's security team, trained to recognize and remove any threats while protecting your body's peaceful residents.

The first line of defense is to restrict the entry of unwanted foreign materials. The skin creates an excellent physical barrier but unwanted guests may still be inhaled or ingested. The acidity of stomach acid, mucosal membranes, and the presence of antibodies in saliva and tears all further help to prevent the entry of these substances into the body.

Four Main Functions
of the Immune System

Physical barriers keep pathogens from entering the body – e.g. skin, mucosa layer of GI tract, antibodies in saliva, pH of stomach

If substances get through the exclusion barrier, they need to be recognized as non-self

Elimination only of unwanted threats, not self or friendly bacteria

Immune memories allow for fast recognition and elimination of repeat offenders
