Vitamin C // Ascorbic Acid

Supply situation

Nutrition surveys in several European countries, such as Austria (37), Ireland (38) and the Netherlands (39), suggest that only close to 50% of the population meet national intake recommendations for vitamin C. 

German survey in 2008 showed that about 30% of all men and women had a daily intake of vitamin C below the recommended level (40). Those most lacking in vitamin C showed a deficiency of about 50–60 mg.

In the U.K., the proportion of those not meeting national recommendations (40 mg/day) is approximately 20% of adults. More recent recommendations of 80 mg/day for vitamin C would not be met by 54% of adults (41).

A dietary surveillance in the U.S. concluded that nearly the entire U.S. population consumes a diet that is not on par with recommendations. People tend not to follow food-based dietary advice and tend to eat too much of what they should reduce and not enough of the foods that they are encouraged to eat (84).
