7. Behavioral Disturbances


Zinc deficiency is common in a number of psychiatric disorders, including dementia, psychotic disorder and anxiety disorders. It is an anti-stress nutrient and is associated with emotional instability.

Its deficiency could lead to a reduction in serotonin synthesis and an increase in anxiety as well as frequent mood changes, anger, sudden fright, depression and low confidence. If not addressed timely, it may even lead to attention deficit hyperactivity disorder (ADHD).


A 2011 study published in the Progress in Neuro-psychopharmacology & Biological Psychiatry journal highlights the role of zinc in neurodegenerative inflammatory pathways in depression.

In addition, a 2010 study published in the Current Opinion in Clinical Nutrition & Metabolic Care journal reviewed several studies on zinc and mood disorders and concluded that an adequate zinc level in the body helps reduce symptoms of depression and anxiety.


8. Vision Problems

According to the American Optometric Association, zinc is essential for vision. High levels of zinc are present in the macula, which is part of the retina.


It enables vitamin A to create melanin, a pigment that protects the eye and even helps you see better at night. Its deficiency can result in poor night vision and cloudy cataracts.

A 2001 study published in the Archives of Ophthalmology suggests that antioxidant and/or zinc supplements may delay progression of age-related macular degeneration (AMD), a leading cause of vision loss among older people.

People who have a risk of developing AMD should consult their doctor about taking a zinc supplement.
