Although it accounts for only 1.2% of all cancers in males, cancer of the testis accounts for about 11%-13% of all cancer deaths of men between the ages of 15-35. Testicular cancer has two peaks according to age. The first peak occurs before the age of 45 and accounts for about 90% of cases of testicular cancer.
For acne, doses of 40-300 milligrams of zinc sulfate two or three times daily with or without food have been taken by mouth for 4-12 weeks. 30-200 milligrams of zinc gluconate prior to a meal daily for 2-3 months has also been studied.
Different forms of zinc contain different amounts of elemental zinc, which refers to the weight of the zinc molecule by itself (Note: Product labels tend to mark the elemental weight) Zinc citrate is approximately 34% zinc by weight. For a dose of 50mg elemental zinc, take 146 mg zinc citrate. Zinc sulfate is approximately 22% zinc by weight. For a dose of 50mg elemental zinc, take 220 mg zinc sulfate. Zinc gluconate is approximately 13% zinc by weight. For a dose of 50mg elemental zinc, take 385 mg zinc gluconate. Zinc monomethionine is approximately 21% zinc by weight. For a dose of 50mg elemental zinc, take 238 mg zinc monomethionine. Zinc should be supplemented daily. Superloading zinc by taking up to 100mg zinc a day is confirmed to be safe in the short term (2-4 months), but because this dose is higher than the 40mg Tolerable Upper Limit (TUL) of zinc, prolonged superloading is not advised.
