Deficiency of vitamin B1 causes beriberi loss of fatigue and appetite. The lack of vitamin B2 causes mucosal injuries in the mouth, lips and tongue. Deficiency of niacin causes nervousness, loss of energy and pellagra, digestive disturbances. Lack of vitamin B6 causes skin irritation, lesions and convulsions.
