Question 3

How common is vitamin E deficiency and why is it rare?

Accepted Answer

Vitamin E deficiency is uncommon in the United States and most developed countries. This is because vitamin E is widely available in foods and true deficiency usually only occurs in people with medical conditions that impair fat absorption.
