Zinc is a mineral that has biological importance for both plants and animals. It is effective in stimulating the activity of hundreds of enzymes. It is responsible for a variety of body functions. It is obtained from food and is also available as zinc supplements. It is beneficial for the immune system and promotes hair growth. Deficiency of zinc is responsible for the death of a large number of children every year. Symptoms associated with its deficiency include diarrhea, anemia, hair loss, loss of appetite, depressed growth, a weak immune system, and abnormal taste.

Deficiency can affect the immune system including the functions of neutrophil and macrophage. A deficiency in the immune system also affects complement and natural cell activity. Zinc supplements counter this deficiency and help improve the altered immune system. Low levels of zinc can cause infection in children, whose immune system is still developing. Zinc supplements can help correct the imbalance in the immune system.

Zinc is effective in the maintenance of skin integrity and mucosal membranes. Abnormality in zinc metabolism causes chronic leg ulcers. Consumption of zinc supplements has been frequently found effective to treat skin ulcers. Patients with low serum zinc levels can take zinc sulfate that may treat leg ulcers though this has not been proved by research.

Balanced levels of this mineral in the body prevent various diseases like cancer. Low levels can lead to the development of cancer, e.g., prostate cancer. Deficiency has been associated with different types of cancer affecting the colon, breast, skin, and lungs. Adequate levels of zinc help in the healthy proliferation of cells.

 

Consumption of zinc supplements has an important role in the health of the brain and the functioning of neurotransmitters. It ensures that the brain membrane gets proper nutrients. It is helpful for regulating dopamine and in the metabolism of melatonin. Anabolism of fatty acids inside the brain membrane involves the use of zinc.

 

Research finds that attention deficit hyperactivity disorder has an association with deficiency of zinc serum in affected children. Consumption of zinc supplements is beneficial for reducing symptoms such as hyperactivity and impulsiveness. It may treat symptoms of hyperactivity in the case of older children that have a high body mass index. However, zinc supplements may not reduce symptoms of attention deficiency.
