                                While inadequate dietary intake is the most common reason for scurvy, a study found that over 7% of the U.S. population has a vitamin C deficiency. However, some individuals with sufficient dietary intake still develop a deficiency, pointing to less common causes. The most scientifically compelling rare cause of vitamin C deficiency is genetic variations that impact how the body absorbs and processes the nutrient.
