According to data from the NHANES 2005-2006 survey, the prevalence of vitamin E inadequacy based on blood concentrations was extremely low among US adults, affecting less than 1% of the population.

According to the National Institutes of Health, vitamin A deficiency is rare in the US, while toxicity from supplements is a more frequent concern. Ingesting excessive preformed vitamin A can lead to a condition known as hypervitaminosis A, which affects multiple bodily systems and, in severe cases, can be fatal.
