What is the daily recommended alllowance for zinc?

Answer 1

The maximum tolerable upper level for long term usage is 25 - 40 mg per day however Zinc interacts with other minerals. It is best to take a mineral complex and top the remaining zinc up to the 25 - 40 mg with separate zinc tablets.

Answer 2

Infants * 0 - 6 months: 2 milligrams per day (mg/day) * 7 - 12 months: 3 mg/day Children * 1 - 3 years: 3 mg/day * 4 - 8 years: 5 mg/day * 9 - 13 years: 8 mg/day Adolescents and Adults * Males age 14 and over: 11 mg/day * Females age 14 to 18 years: 9 mg/day * Females age 19 and over: 8 mg/day

Answer 3

The most important consideration is to get reasonably close to one seventh as much copper as zinc in the diet. Those two interfere with each other. I had a well liked relative die recently who was on blood thinners when she started to bleed from a brain blood vessel. She had been taking large zinc supplements but no copper, and copper is essential for strong arteries. The reverse is not good either. I suspect that a zinc deficiency can cause a swollen prostate. You may see a discussion of copper nutrition that also has some zinc information in the first URL. You may see a copper and zinc food content table in the second URL expressed as weight per calorie, the most useful way.

Added:RDA = daily dietary intake level

Upper limit = UL = Tolerable upper intake levels

• Copper: RDA 900 µg = 0.900 mg (UL: 10 mg)
• Zinc : RDA 11 mg (UL: 40 mg)

Answer 4

In 2000, the National Academy of Sciences set a tolerable upper limit (UI) of 40 milligrams for daily intake of zinc for adults age 19 and over. The establishment of this limit was largely related to the ability of zinc, especially supplemental zinc, to impair the status of other nutrients.
