Which deficiency is associated with potential depressive symptoms?

Iron deficiency is associated with potential depressive symptoms due to the critical role that iron plays in the production of neurotransmitters, such as serotonin and dopamine, which are essential for mood regulation. When the body's iron levels are low, it can lead to inadequate oxygen delivery to the brain and other tissues, affecting overall energy levels and cognitive function. This disruption can contribute to feelings of fatigue, irritability, and ultimately depressive symptoms.

Moreover, studies have shown that individuals with iron deficiency anemia are more likely to report symptoms of depression. This connection highlights the importance of maintaining adequate iron levels for both physical health and mental well-being.
