  • Zinc acetate is easily absorbed and is used in throat lozenges.
  • Zinc chloride is in styptic pencils, deodorants and in wood preservatives.
  • Zinc gluconate is absorbed well. Zinc gluconate is the type most commonly used in lozenge form to kill upper respiratory viruses. One should select brands that do not use citric acid or tartaric acid for flavoring, as these appear to impair the effectiveness.

Zinc oxide is an amorphous white or yellowish powder, ZnO, used as a pigment, in compounding rubber, in the manufacture of plastics. . .or you can put it on your face as it is in pharmaceuticals and cosmetics. Also called Chinese white, zinc white.
  • Zinc picolinate is the most easily absorbed form of zinc. Next are the citrate, gluconate and acetate forms.
  • Zinc sulfate may cause stomach irritation. Zinc sulfate (ZnSO4) is a clear, crystalline, water soluble man-made synthetic chemical compound. The hydrated form, ZnSO4·7H2O, is historically known as “white vitriol“. Zinc sulfate occurs naturally as the mineral goslarite, and can be prepared by reacting zinc with sulfuric acid.

Cautions & Comments about Zinc:

  • A significant amount of zinc is lost through perspiration
  • Compounds called phytates that are found in grains and legumes bind with zinc so that it cannot be absorbed.
  • Oral zinc should not be taken with foods that will reduce its absorption, such as coffee, bran, protein, phytates (see above), calcium, or phosphorus.
  • Supplements should be stored in a cool, dry location, away from direct light, and out of the reach of children.
  • Do not take a total of more than 100 milligrams of zinc daily.  While daily doses under 100 milligrams enhance the immune response, doses of more than 100 milligrams can depress the immune system.
  • If you take both zinc and iron supplements, take them at different times.  If these two minerals are taken together, they interfere with each other’s activity.
  • The consumption of hard water also can upset zinc levels.
  • Diseases affecting zinc absorption include: Diarrhea, kidney disease, cirrhosis of the liver, diabetes, or the consumption of fiber, which causes zinc to be excreted through the intestinal tract, may lower zinc levels.
  • People who have hemochromatosis, are allergic to zinc, or are infected with HIV should not take supplemental zinc.
  • Ulcers in the stomach or duodenum may be aggravated by supplements as well. Those with glaucoma should use caution if using eye drops containing zinc.
  • Overuse of supplemental zinc during pregnancy can increase the risk of premature birth and stillbirth, particularly if the supplement is taken in the third trimester.
