Are We Getting Enough Vitamin C?


A new report published in Critical Reviews in Food Science and Nutrition recommends raising the daily allowance (RDA) of vitamin C.

Are we getting enough vitamin C in our diets? According to a new report published in Critical Reviews in Food Science and Nutrition, the recommended daily allowance (RDA) of vitamin C should be raised, and we should all consume more vitamin C-rich foods. In fact, the scientists believe that the RDA of vitamin C should be more than doubled.

Currently, the RDA for both the United States as well as Canada is 75 mg for women and 90 mg for men. The researchers call for raising it to 200 mg for adults. The current RDA is sufficient to prevent scurvy, but it may not be high enough to help to reduce risk of chronic diseases such as stroke, cancer, and heart disease. A diet higher in vitamin C may also help to prevent high blood pressure, chronic inflammation, and atherosclerosis (hardening of the arteries), as well as boost immune response.

Who is at risk for low vitamin C levels?

  • the elderly
  • college students (whose diets may be lacking in fruits and vegetables)
  • smokers
