Question 2

A hypochondriac patient, who drinks a large bottle of V8 and takes multiple supplements every day, develops a painful flush and skin lesions. She is lethargic, acting like she may be depressed, and complains of numbness in her limbs. Based on her history, identify which B vitamins she is taking in excess, and specifically indicate which vitamin is likely causing each of her symptoms.

Answer to Question 1

C

Answer to Question 2

High levels of niacin lead to the painful flush. Vitamin B6 toxicity is responsible for the skin lesions, and the behavioral symptoms and the numbness. Although the other B vitamins do not have toxicity symptoms reported, the interdependence of the vitamins on one another could lead to additional health problems that may be undetected at this early point.
