Vitamin C Sources

The human body requires vitamin C for various purposes. Known also as ascorbic acid, this nutrient is known to lower the risk of cancer and do a lot of other great benefits to the health. This article will discuss ascorbic acid as well as top vitamin C sources to help you with your health and diet.

Vitamin C as an Essential Nutrient

Vitamin C is a water-soluble nutrient that is essential for the body’s growth and development. When we say this vitamin is water-soluble, it means it dissolves in water and unused vitamin C can leave in the body and is excreted through the urinary tract. This only means that a continuous supply of vitamin C is needed to supply the body with the necessary nutrient for proper health.

The main function of ascorbic acid is repairing and supporting the growth of tissues in the body. It supports the growth of the skin, ligaments, tendons, and blood vessels. It can also help in healing wounds and repairing cartilage, teeth, and bones. Besides this, vitamin C is considered an antioxidant, too. It blocks damage caused by free radicals coming from the natural breaking down of foods and exposure to tobacco and radiation. In line with this, vitamin C as an antioxidant is known to prevent certain health conditions like heart disease, arthritis, and cancer.

The Recommended Dietary Allowance for Vitamin C

The body cannot make its own vitamin C and it also does not store the nutrient. With this, it is very important that we supply the body with plenty of vitamin C from food sources and even supplements, if necessary.

However, it is very important that we know the right dosage of vitamin C to take for the best health possible. This is true because deficiency and overdose can both cause health problems. For instance, vitamin C deficiency can offer problems such as bleeding gums, skin discoloration, poor wound healing, weak immune function, and respiratory infection. On the other hand, toxicity can offer diarrhea, increased levels of uric acid, and kidney stones. Check out the recommended dietary allowance (RDA) for vitamin C from the National Academy of Sciences to guide your everyday food intake:

The Offers of Vitamin C Supplements

Vitamin C can also be taken as a daily dietary supplement. It is available in various forms such as vitamin C powder, capsules, tablets, and caplets. However, experts recommend getting vitamin C from food sources instead of supplements like vitamin C tablets.

But, people who are prone to deficiency are often required to take supplements. This includes smokers, alcohol drinkers, and steroid users. People who eat limited variations of foods such as those following fad diets may also need supplementation. The same is true for people with medical conditions such as cancer and digestive issues. Infants who are fed with boiled cow’s milk or evaporated milk may also need vitamin C supplementation as the boiling process of the milk can destroy the milk’s vitamin C contents.
