Vitamin B6, also called pyridoxine, plays a role in the body's metabolism and energy production, protecting neurons and producing neurotransmitters, which are important substances for the proper functioning of the nervous system.
This vitamin is present in foods like fish, liver, potatoes and fruits, and its lack causes symptoms in the body such as tiredness, depression, confusion and mental swelling in the tongue. See all the signs here.
