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
?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.
