title: The effect of supplement use on vitamin C intake.
abstract: According to results from the 2004 Canadian Community Health Survey-Nutrition, Canadians get an average of 132 milligrams of vitamin C a day from food. About one adult in five has inadequate dietary intake of vitamin C. A third of Canadians take vitamin C supplements, which add 100 milligrams to total average daily intake. Supplement use lowers the overall percentage of adults with inadequate intake by 5 percentage points to 17%. Smokers, people who eat fruit and vegetables infrequently, and members of households with low income and low educational attainment tend to have relatively low vitamin C intake.
