Vitamin B-6 is required for the brain to produce serotonin, dopamine, norepinephrine and GABA and for myelin formation. It is also necessary for the proper maintenance of red blood cell metabolism, the nervous system, and the immune system.
Deficiencies can cause dermatitis (skin inflammation), depression, confusion, cognitive dysfunction, convulsions, and increased risk of heart attack.
A deficiency in vitamin B-6 can be induced by certain drugs, including antidepressants. A vitamin B-6 deficiency is characterized by mental changes such as fatigue, nervousness, irritability, depression, insomnia, dizziness, confusion, and nerve changes. These mental changes are related to the body’s decreased ability to manufacture neurotransmitters.
Cooking and freezing destroy vitamin B-6 so eating fruits and vegetables raw and other sources with the shortest cooking times required will help ensure maintenance of B-6.
Mild deficiency of vitamin B-6 is common in the U.S.
