Vitamin C modulates immune function through redox-sensitive cell signaling pathways and by directly protecting structural components of cells. For example, oxidants are known to inhibit neutrophil motility, in part by decreasing membrane fluidity. Moreover, oxidants inhibit the regeneration of vitamin E.

A component of neutrophil membranes. Thus, it is likely that vitamin C enhances neutrophil motility through scavenging oxidants and regeneration of vitamin E.

Vitamin C is an antioxidant, which means that it neutralizes free radicals that damage cells and tissues. Studies show that vitamin C may also protect against heart disease. For this reason, it is important to get plenty of vitamin C from fruits and vegetables.

In addition, vitamin C contributes to the immune system and maintains bone and blood vessel health. It also supports the production of B and T-cells, which support a healthy immune response. These specialized cells fight pathogens and help keep the body healthy. They can also protect the skin and act as a barrier against foreign invaders.

Recent research has shown that vitamin C supports the immune system. It protects against oxidative stress, increases the activity of gene-regulatory enzymes, and enhances phagocytosis and reduce the incidence of infections, such as the common cold. It may also recover from colds faster.

Vitamin C may also improve absorption of iron. As such, it can help prevent iron deficiency. Vitamin C also aids in the production of white blood cells, which help the body fight infections. It also protects against free radicals and boosts wound healing. Further, vitamin C may reduce the risk of osteoarthritis.

Vitamin C is also helpful in the treatment of common respiratory diseases. It inhibits the production of histamine, a molecule released by mast cells and eosinophils in the body. Histamine is a messenger that induces vasodilation and increased capillary permeability. As a result, vitamin C reduces the levels of histamine.

The National Institute of Health recommends that adults consume at least 90 milligrams of vitamin C daily. People who consume less than this amount should see a health care provider. Vitamin C is best as part of a balanced diet. In addition to helping the immune system, it also plays a role in wound healing and helps absorb nonheme iron.

Research has also suggested that prevent and treat respiratory, infections by modulating immune cell functions. In addition. Research has shown that vitamin C intake of 100-200 mg per day may help prevent and treat respiratory and systemic infections. However, higher doses of vitamin C may be necessary for treating infections. There are many types of vitamin C available on the market.
