These studies suggest that zinc supplementation and higher dietary zinc intake are associated with reduced risk and alleviation of depressive symptoms, though further research is needed to confirm its effectiveness as a monotherapy or adjunctive therapy.
Zinc, an essential micronutrient, plays a crucial role in various biological processes, including cell growth, immune function, and neuronal activity. Recent research has explored the relationship between zinc levels and depression, suggesting that zinc deficiency may be linked to depressive symptoms and that zinc supplementation could potentially alleviate these symptoms.

The collective evidence suggests a strong association between zinc deficiency and depression. Higher dietary zinc intake and zinc supplementation, particularly when used alongside conventional antidepressant treatments, appear to reduce the risk and severity of depressive symptoms. Gender-specific differences and the involvement of inflammatory and neurodegenerative pathways highlight the complex role of zinc in mental health. Further research is needed to confirm these findings and to explore the potential of zinc as a monotherapy for depression.
