Benefits of Zinc

When our founder, Julie Dickens, created Cold FAid®, her mission was to help provide an effective and efficient strategy for combating the common cold. Our strategy includes the use of 4 medications - zinc gluconate lozenges, antihistamine, nasal decongestant PE and a pain reliever. Within the next two blogs, we will be digging into the benefits of zinc.


Zinc is an efficacious homeopathic medication to treat a cold. How it works:  

  • First, a majority of colds are caused by rhinovirus.  
  • Zinc affects rhinovirus and certain other viruses. The Mayo Clinic writer, Bernt A. Bauer, M.D., along with many other researchers, theorize that zinc works by blocking the virus from
    • attaching to the cells lining the nose 
    • replicating if it enters a nasal cell. 

Lozenges should have 13 to 23 milligrams. The Best Health zinc lozenges used in the Cold FAid® kit contain 13.3 milligrams of zinc. To treat a cold, one lozenge every 2-4 hours is needed for a total of 6 lozenges per day. This delivers 79.8 mg (within the studied antiviral dose of over >75 mg/d).  While 40 milligrams per day is the recommended daily allowance (RDA) by the Food and Nutrition Board of the Institute of Medicine, Hallie Levine from Health.com mentions that exceeding the limit for three or five days is reasonable.


To fight a cold, suck on one lozenge every 2-4 hours at the first sign of a cold. Take the first lozenge within 24 hours of your symptoms beginning. While you may experience nausea or a metallic taste as side effects, the benefits result in a shorter and milder cold symptoms. Due to this, make sure to take a zinc lozenge after eating a meal as the lozenge coats your throat. Do not crush or swallow the lozenges whole. Citric fruits and citric juices deactivate the zinc if taken 30 minutes before or after. 


At Cold FAid®, we hope you and your families stay healthy this winter by reducing the length of your cold with zinc!
