Vitamin C, or technically L-ascorbic acid, is an essential water soluble vitamin known to exhibit antioxidant properties.
It is the most famous of all vitamins and was discovered in 1932 when scurvy killed 2 million sailors between year 1500-1800. Unlike most animals, humans are unable to synthesize vitamin C so it is considered to be an essential nutrient.

* Adequate Intake (AI)
Due to its function as an antioxidant and its role in immune function, vitamin C has been promoted as a means to help prevent and/or treat numerous health conditions. Supplements are most common in the form of ascorbic acid. which has equivalent bioavailability to that of naturally occurring ascorbic acid in foods, such as orange juice and broccoli. Other forms of vitamin C supplements include sodium ascorbate; calcium ascorbate; other mineral ascorbates; ascorbic acid with bioflavonoids.
You should be able to get all the vitamin C you need by eating a well balanced diet. But due to lifestyle and busy schedule and vitamin c being water soluble meaning heat sensitive -you may not meet the daily requirement and opt for supplements. Please keep in mind the dosage and talk to a health professional for further advice.
