From the FDA Drug Label
Recommended daily intakes by intravenous route are the following:
- In pediatric patients:
- Premature infants: 0.3 to 0.35 mg zinc/kg/day,
- Full term infants: 0.1 to 0.2 mg zinc/kg/day,
- Children: 5 mg zinc/day.
- In adults: 3 to 15 mg zinc/day.
The recommended daily intake of zinc to improve prostate function is not explicitly stated in the provided drug labels. However, the labels provide general recommended daily intakes of zinc for different patient groups.
- For adults, the recommended daily intake is 3 to 15 mg zinc/day 1. There is no specific information on the recommended daily intake of zinc to improve prostate function.
From the Research
The recommended daily intake of zinc for prostate health should not exceed 75 mg per day, as higher doses may increase the risk of lethal and aggressive prostate cancer. Men concerned about prostate function should aim for a daily intake of 15-30 mg of zinc, with most supplements providing around 15 mg per dose 2. It's essential to note that excessive zinc can interfere with copper absorption and potentially cause immune system problems. Zinc is particularly concentrated in the prostate gland and plays a role in maintaining proper prostate function by supporting cellular growth, hormone metabolism, and immune function within the gland. Food sources of zinc, such as oysters, red meat, poultry, beans, nuts, and whole grains, can contribute to daily intake alongside supplements if needed.
Some key points to consider:
- The bioavailability of different zinc compounds can vary, with zinc gluconate and zinc citrate showing higher bioavailability in the prostate compared to zinc sulfate 3.
- The risks and benefits of zinc supplementation should be carefully evaluated, as excessive intake can cause copper deficiency and other health problems 4.
- While saw palmetto is an herbal product used to treat symptoms related to benign prostatic hyperplasia, its effectiveness and potential interactions with zinc supplements are not well understood 5.
- Some studies suggest that long-term supplemental zinc intake may be associated with reduced risk of advanced prostate cancer, but more research is needed to confirm these findings 6.
In general, men should consult with a healthcare provider before starting zinc supplementation, as individual needs may vary based on age, health status, and medications being taken. It is crucial to prioritize a balanced diet and not rely solely on supplements to meet daily zinc needs.
