What Is Scurvy?
•
Scurvy is a vitamin C (ascorbic acid)
deficiency that results from a few weeks to
months of no vitamin C or 20 to 40 days
•
We’ve known of it since ancient Greek and
Egyptian times
•
It was most common in sailors throughout the
16th-18th century due to vitamin C deprivation
for long periods of time
•
Cases today are rare
Why Do We Need Vitamin C?
•
Vitamin C is essential for the production of collagen and the absorption of
iron
•
We are unable to make vitamin C on our own so we need to get it from other
sources like citrus fruits
Causes
•
It is caused by environmental factors, not genetic factors

Deprivation of vitamin C due to famine, anorexia, restrictive diets, or difficulty orally ingesting
