niacin has been researched along with Depression in 76 studies
Niacin: A water-soluble vitamin of the B complex occurring in various animal and plant tissues. It is required by the body for the formation of coenzymes NAD and NADP. It has PELLAGRA-curative, vasodilating, and antilipemic properties.
vitamin B3 : Any member of a group of vitamers that belong to the chemical structural class called pyridines that exhibit biological activity against vitamin B3 deficiency. Vitamin B3 deficiency causes a condition known as pellagra whose symptoms include depression, dermatitis and diarrhea. The vitamers include nicotinic acid and nicotinamide (and their ionized and salt forms).
nicotinic acid : A pyridinemonocarboxylic acid that is pyridine in which the hydrogen at position 3 is replaced by a carboxy group.
Depression: Depressive states usually of moderate intensity in contrast with MAJOR DEPRESSIVE DISORDER present in neurotic and psychotic disorders.
