Zinc
About Zinc
Zinc is a nutritional supplement used to prevent and treat Zinc deficiency. It plays an essential role in supporting immune function, wound healing, protein synthesis, DNA synthesis, and normal growth and development. Your doctor may also recommend it to help manage acute diarrhoea, particularly in children, as part of oral rehydration therapy.
For the best results, take Zinc exactly as suggested by your healthcare provider. It is generally recommended to take this supplement on an empty stomach for better absorption. However, if it causes stomach upset, you may take it with food. Maintaining a balanced diet rich in essential nutrients can further support your recovery and overall health.
While Zinc is generally well tolerated, some people may experience mild side effects such as nausea, stomach discomfort, vomiting, diarrhoea, or a metallic taste in the mouth. Contact your doctor immediately if you develop severe abdominal pain, persistent vomiting, signs of an allergic reaction, or any unusual symptoms.
Before taking Zinc, tell your doctor if you have kidney disease, a history of copper deficiency, or gastrointestinal conditions that may affect nutrient absorption. Do not take this supplement if you are allergic to Zinc or any of the other ingredients in the formulation.
This supplement may interact with certain antibiotics (such as tetracyclines and quinolones), penicillamine, iron supplements, and calcium supplements, reducing the absorption of one or both medicines. If you are pregnant, breastfeeding, or are an older adult, consult your healthcare provider before taking this supplement.

Patients Concern
Disease/Condition Glossary
Mineral deficiencies: A mineral deficiency occurs when the body does not absorb or get enough minerals from food. Minerals are necessary for body development and the prevention of diseases. Mineral deficiency can lead to many health problems, like a weakened immune system, weak bones, and fatigue. The human body requires different minerals for bodily functions and proper growth. Mineral deficiency could occur due to a lack of minerals in the diet, an increased need for minerals, or difficulty absorbing minerals from food. Zinc deficiency may cause loss of appetite, altered sense of smell or taste, decreased immune function, and a slowed growth rate.
