Zinc Deficiency and the Mind
It is believed that a zinc deficiency can lead to low energy and depression. Many patients who are suffering from psychological conditions, such as depression, bipolar disorders, ADD, and even schizophrenia, have low zinc in their blood. Also, a connection has been made between people who have behavioral problems, and imbalances of essential minerals — not only zinc, but also copper, magnesium, calcium, and manganese.
A zinc deficiency is of particular concern, as researchers believe that the mineral actually acts as a neurotransmitter. An imbalance could then disrupt healthy mental functioning. Low levels can cause irritability, fatigue, a faulty memory, and diminished senses, specifically taste and smell. Also, as zinc balances with copper in the body, a deficiency implies high levels of copper in the blood. Excess copper is linked to depression, violence, and learning disabilities.
