Zinc sulfate monohydrate is an inorganic compound with the chemical formula ZnSO4. It is a white crystalline solid. Zinc sulfate is used as a dietary supplement, and it is sometimes combined with vitamin C to help reduce the length and severity of symptoms of the common cold. It is also available as an over-the-counter medication.

Zinc is a mineral that naturally occurs in the environment and in food. It can also be found in human, animal, and plant tissues. Zinc can enter the body through inhalation, skin contact, or oral consumption. It is an essential nutrient that supports normal growth and development, and it helps maintain the health of tissues.

When ingested, zinc sulfate monohydrate is absorbed in the digestive tract and passes into the bloodstream. It binds to proteins and enters cells throughout the body, where it may be found in the brain, bone, eye, intestine, heart, liver, kidney, lungs, muscle, pancreas, and prostate. It is important for the normal function of many enzymes, including alkaline phosphatase and both RNA and DNA polymerase. It is necessary for protein synthesis, wound healing, and maintaining normal blood stability and tissue function. Zinc is also involved in the metabolism of phosphorus, governs contractions of muscles, and supports the senses of taste and smell.

Long-term exposure to zinc sulfate can cause changes in the normal balance of nutrients in the blood. This can lead to nutritional deficiencies and affect the stomach and intestines, the respiratory system, and the pancreas. It can also cause abnormalities in the urine, sweat, and feces.
