Q

Vitamin B3 defiency is known as:

A. Night blindness
B. Pellagra
C. Rickets
D. Pernicious anemia

A

B. Pellagra

Pellagra is a disease caused by low levels of niacin, also known as vitamin B-3. It’s marked by dementia, diarrhea, and dermatitis, also known as “the three Ds”. May also cause swelling and redness in the mouth. If left untreated, pellagra can be fatal.
