An iron deficiency is most commonly linked to the development of anemia, which is a condition when there’s a lack of healthy red blood cells being produced. Providing these double-deficient rats with either iron (Fe) or preformed docosahexaenoic acid (DHA)/eicosapentaenoic acid (EPA) alone affected brain monoamine pathways differently from … Even more, it helps regulate mood, supports sexual function, regulates appetite, and impacts sleep.

Since vitamin B6 and iron play important roles as cofactors for the synthesis of serotonin, the researchers tested to see whether or not low levels of the nutrients played a role in the incidence of panic attacks. Iron deficiency reduced 3H-nisoxetine binding to the NE transporter in locus ceruleus and anteroventral thalamic nucleus in males but not females.

Healthcare professionals do not fully understand why some people develop serotonin deficiency. The symptoms, not the specific levels of serotonin, matter most. Low serotonin can also affect physical health. Since iron is a cofactor for the rate-limiting enzymes involved in serotonin and NE synthesis, decreased iron in the hippocampus due to Cp deficiency could result in impaired production of these monoamines and down-regulate BDNF signaling, which together promote an anxiety phenotype. Serotonin is a hormone that is also called hydroxytryptamine (5-HT), it is located in the pineal gland, blood platelets, the digestive tract and the brain. Iron is required to synthesize both serotonin and dopamine, and serotonin receptors are known to regulate iron-carrying proteins. 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. Some feel it is an epidemic in the United States. Serotonin plays a role in many key functions, including memory, sleeping, hunger, digestion, and mood.

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. A new study from Vanderbilt Medical Center illustrates the power of the in silico — or computer-based — research method to study the connection between iron levels and the neurotransmitter serotonin. From that research there appears to be three factors which are pertinent to the disease: brain concentrations of iron, brain dopamine concentrations and genes. This means that it helps carry a nerve signal across a synapse. Taking antidepressant medications called selective serotonin reuptake inhibitors (SSRIs) may improve symptoms of serotonin deficiency. Iron helps metabolize proteins and plays a role in the production of hemoglobin and red blood cells, helping to prevent anemia from forming.
