Vitamin C is essential for tissue maintenance, immune strength, and as an antioxidant. It can be found in fruits and vegetables or taken as a supplement. Overdosing is difficult, but daily intake is necessary as the body cannot store it. Topical vitamin C can improve skin elasticity and act as a natural defense against the sun, but results vary by individual.
Vitamin C is a nutrient that is essential for human growth and development. The function of vitamin C in the body is varied: the vitamin is very important for the maintenance of connective tissues and cartilage, and it can act as an antioxidant. It helps keep the immune system strong, plays a role in many of the body’s enzymatic activities and conversions, and applied topically can improve skin elasticity and act as a natural defense against the sun.
One of the most important roles that vitamin C plays in the body is tissue maintenance and tissue repair. The tissues that connect organs, the tendons and ligaments that allow movement, and the scar tissue that forms after injury are all supported by vitamin c. Vitamin C also acts as an antioxidant by allowing the body’s enzymes to target and destroy free radicals. An equally important function of vitamin C is immune strength: the vitamin is essential for the proper functioning of the immune system, which helps prevent disease and illness. Vitamin C deficiency can cause numerous health problems, but those problems can be avoided by eating foods with naturally high levels of vitamin C, including most fruits and vegetables, or by purchasing vitamin C supplements.
The fact that vitamin C is essential does not necessarily mean that consuming a large amount of vitamin C will improve health. Vitamin C supplements are commonly promoted as some kind of cure for any ailment, and are regularly sold with promises of increased immunity, the power to prevent cancers and chronic diseases, and many other pro-health claims. Whether or not these claims have scientific truth is a matter of great controversy.
Most governments around the world have set modest recommendations for daily intake of vitamin C in line with the amount of vitamin ca a person should naturally consume from a diet rich in fruits and vegetables. As of 2010, the United States Department of Agriculture recommended a daily dose of at least 75 milligrams for women and 90 milligrams for men. The UK Food Standards Agency recommended 40 milligrams per day for all adults, and the World Health Organization recommended 25 to 30 milligrams per person per day.
Vitamin C is water soluble, which means that excess vitamin C in the body is easily eliminated. This role of vitamin C makes it difficult to overdose, and there are relatively few side effects from consuming too much. However, it also means that vitamin c must be consumed on a daily basis, as the body has no capacity to store additional reserves.
The vitamin can also be used externally. Cosmetic companies in particular have tried to capitalize on vitamin C’s preservative role by adding it as an ingredient to topical lotions and creams that promise to slow environmental damage to the skin, renew the skin, and reduce wrinkles. In high enough concentrations, the collagen-building function of vitamin C that is so essential for internal tissue maintenance can sometimes help improve skin regeneration and elasticity, and the vitamin has been shown to block harmful rays. ultraviolet from the sun. However, results vary by individual. There is little scientific evidence to support vitamin C as a universal wrinkle reducer, and vitamin C creams alone should not be relied on to protect skin from the sun or other harmful environmental elements.
