More about this report

Zinc can shorten the duration of a cold, but found that a not all products provide a dosage that's been proven effective. Zinc can also slow the progression of advanced macular degeneration of the eye, but the amount you need may be less than some products contain — and there is a risk of causing copper deficiency from taking too much zinc!

Zinc supplements may be useful in treating other conditions including acne, depression, and anorexia nervosa, and, of course, in preventing and correcting zinc deficiency. But which form of zinc should you choose, and which products provide what you want at the lowest cost? The answers are in our report.

We tested tablets, capsules, and lozenges, as well as a powder and a liquid, to be sure they contained what they claimed and met other quality standards. 

In this comprehensive report about zinc supplements and zinc lozenges, you'll get test results and quality ratings for 24 zinc products (including 8 that passed our voluntary Quality Certification Program). You'll learn:
    • Which zinc supplements passed testing, which failed, and which were selected as CL's Top Picks for providing the right ingredients and the best value   
    • Which zinc lozenges provide a dosage known to work -- and which do not
    • What zinc can and cannot do for your health  
    • If certain forms of zinc, like zinc gluconate, zinc acetate, and zinc citrate are better absorbed than others  
    • The zinc dosage to treat conditions including colds, macular degeneration, and zinc deficiency 
    • What the "zinc challenge" is and whether or not it is a reliable method for determining zinc deficiency or adequacy
    • The potential side-effects of zinc and other concerns with zinc, including drug interactions
