What is the Connection Between Vitamin C and the Immune System?

T. M. Robertson

Medical science has shown Vitamin C to be a vital component in maintaining a healthy immune system. After vitamin C is ingested, the body is able to produce more white blood cells that in turn help prevent viruses from entering and wreaking havoc on the body. Regular intake of vitamin C can also prevent other health problems such as cardiovascular disease, high blood pressure, and various forms of cancer. Vitamin C can be obtained through regular diet, and can also be taken in the form of supplements. In addition, experts recommend that dosages be spread throughout the day to maximize absorption rates.

Vitamin C and the immune system have been studied in detail by the medical community. Since the body cannot produce vitamin C on its own, one must consume it through diet or supplements. When people think of vitamin C, many automatically think of orange juice, but vitamin C is actually prevalent in many fruits and vegetables. Most people will get more than enough of the vitamin as long as they ingest at least six fruits and vegetables a day. Supplements are also available at most supermarkets and nutrition stores.

While experts seem to agree on the correlation between vitamin C and the immune system, there is less agreement about daily recommended dosage. According to the US Food and Drug Administration, adults should consume at least 60 mg per day. Other experts conclude that adults should be taking upward of 200 to 1,000 mg per day. Taking more than the recommended amount will result in the body eliminating the excess through the urine. In rare cases, it is reported that people can overdose if they take too much, but that number has not been determined.

When vitamin C enters the body, there is an increased production of white blood cells. This increase allows the body to help prevent viruses from taking hold and spreading throughout the system. Vitamin C is not only a major contributing factor in boosting the immune system and preventing colds and flus, but it also helps lower rates of cancer, heart disease, and high blood pressure.
