Dr. David L. Katz, MD, MPH
Preventive Medicine
In today's world of fortified foods, vitamin deficiencies are less common than they used to be -- but shortages still exist. In this video, I will describe some of the problems that can result from vitamin shortfalls.

The following are some results of vitamin deficiencies:

Vitamin A: Night blindness, poor growth, reproduction problems, dry skin
Vitamin D: decreased bone mass, rickets
Vitamin E: (rare) low birth weight, problems absorbing fat
Vitamin K: (rare) problems with blood clotting
Vitamin B6: convulsions, depression, nausea, greasy, flaky skin
Folic Acid: impairs growth, anemia
Vitamin B12: anemia, fatigue, nerve damage (strict vegetarians are at risk)
Vitamin C: scurvy
