We recently showed that a combined deficiency of iron (ID) and n-3 fatty acids (n-3 FAD) in rats disrupts brain monoamine metabolism and produces greater memory deficits than ID or n-3 FAD alone. Racism and economic stress contribute, too. In the serotonin synthesis system of the brain, vitamin B6 is a coenzyme for tryptophan hydroxylase, which is involved in the conversion of tryptophan into 5-hydroxytryptophan and iron serves as a cofactor for aromatic L-amino acid decarboxylase involved in the formation of serotonin from 5-hydroxytryptophan.

Serotonin helps your body’s nervous system communicate.
