NOW ZINC 50MG 120 CAPS
Zinc is a mineral. It is called an “essential trace element” because very small amounts of zinc are necessary for human health. Since the human body does not store excess zinc, it must be consumed regularly as part of the diet. Common dietary sources of zinc include red meat, poultry, and fish. Zinc deficiency can cause short stature, reduced ability to taste food, and the inability of testes and ovaries to function properly.
It treats and prevents zinc deficiency and its consequences, including stunted growth and acute diarrhea in children, slow wound healing, and Wilson’s disease. There is some scientific evidence to support its use for some of these conditions. But for most, there is no good scientific evidence to support its use.
Coronavirus disease 2019 (COVID-19): While zinc may have benefit for the common cold and other airway infections, there is no good evidence to support using it for COVID-19. Also, zinc gluconate 50 mg daily does not seem to be beneficial. Follow healthy lifestyle choices and proven prevention methods instead.
USES AND EFFECTIVNESS of NOW ZINC 50MG 120 CAPS
- Zinc deficiency. Zinc deficiency might occur in people with severe diarrhea, conditions that make it hard for the bowel to absorb food, liver cirrhosis and alcoholism, after major surgery, and during long-term use of tube feeding in the hospital. Taking zinc by mouth or giving zinc intravenously (by IV) helps to restore zinc levels in people who are zinc deficient. However, taking zinc supplements regularly is not recommended.
Likely Effective for
- Diarrhea. Taking zinc by mouth reduces the duration and severity of diarrhea in children who are undernourished or zinc deficient. Severe zinc deficiency in children is common in developing countries. Zinc 20 mg daily is the most common dose used. But doses of 5-10 mg also seem to work and cause less vomiting.
- An inherited disorder that causes copper to build up in many organs (Wilson disease). Taking zinc by mouth improves symptoms of an inherited disorder called Wilson disease. People with Wilson disease have too much copper in their bodies.
When taken by mouth: Zinc is LIKELY SAFE for most adults when taken by mouth in amounts not larger than 40 mg daily.
Routine zinc supplementation is not recommended without the advice of a healthcare professional. In some people, zinc might cause nausea, vomiting, diarrhea, metallic taste, kidney and stomach damage, and other side effects.
Zinc is POSSIBLY SAFE when you take it by mouth in doses greater than 40 mg daily, especially when these doses you take it only for a short period of time.
There is some concern that taking doses higher than 40 mg daily might decrease how much copper the body absorbs.
Decreased copper absorption may cause anemia. Taking high amounts of zinc is LIKELY UNSAFE. High doses above the recommended amounts might cause fever, coughing, stomach pain, fatigue, and many other problems.
Taking more than 100 mg of supplemental zinc daily or taking supplemental zinc for 10 or more years doubles the risk of developing prostate cancer.
There is also concern that taking large amounts of a multivitamin plus a separate zinc supplement increases the chance of dying from prostate cancer. Taking 450 mg or more of zinc daily can cause problems with blood iron. Single doses of 10-30 grams of zinc can be fatal.
To the skin: Zinc is LIKELY SAFE for most adults when you apply it to the skin. Using zinc on broken skin may cause burning, stinging, itching, and tingling.
