Zinc Lozenges Can Shorten the Duration of the Common Cold

Zinc Lozenges Can Shorten the Duration of the Common Cold

During cold season, a large variety of cold remedies are advertised and sought after, but few actually address the root causes of colds.  Most cold medicines suppress symptoms, or at best slowly reduce cold symptoms, but they do not improve the status of the immune system or aid proper nutrition.  In addition, many unpleasant side effects can accompany the use of cold medicines which can make them undesirable solutions. 

Possible Side Effects of Common Cold and Flu Remedies:

  • Insomnia
  • Hyper-excitability
  • Dry mouth
  • Constipation
  • Drowsiness
  • Interaction with prescription medications


Zinc plays a central role in the proper functioning of innumerable bodily processes.  It is found throughout the body and it is a key element in regulating the immune system.  Research has shown that it may also generate anti-viral action in the body.  Since it effectively manages these areas of bodily health, studies have been conducted to determine its effectiveness in treating and relieving common colds.   

Good Food Sources of Zinc:

  • Lean Meats
  • Liver
  • Eggs
  • Seafood
  • Whole Grain Breads
  • Cereals

Clinical trials have shown that zinc lozenges can provide enough zinc to effectively shorten the duration of the common cold.  The studies demonstrated that daily doses of zinc under 75mg have no effect on common colds, but doses that are over 75mg can reduce the duration of colds by about 20-40%.   The studies implied that low doses of zinc are ineffective, but the higher the dose of zinc, the more effective it would be in reducing the duration and symptoms of colds.  Further studies will be required to determine the ideal dosage for this purpose in order to maximize the effectiveness of this safe and natural remedy for the common cold.
