  • Blocks & Locks Viruses....Cold!
  • Daily Dose Lozenges
  • Dietary Supplement

100% Herbal Virus Blocker

  • Blocks viruses from entering human cells*
  • Works to target and block viruses before they multiply*
  • Begins working in minutes...not hours.

The bioactives in Blockade actually bind themselves to viruses, coat the viruses, and block their ability to attach to and enter human cells.

Blockade, with the exclusive extract, ViraBloc, is the first all-herbal, natural therapeutic that acts to block viruses from entering human cells therefore preventing them from replicating.

In-vitro, laboratory studies of this patent-pending extract have demonstrated up to a 100% success rate in inhibiting the entry of enveloped viruses (like influenza).

Dissolves Fast-Acts Fast

Because Blockade is a fast dissolving, great tasting, all natural lozenge that you hold under your tongue, it enters and starts working in your bloodstream in minutes...not hours, unlike anti-virals whose primary delivery mechanism has to work through the GI tract (stomach lining).

Suggested Use

To help maintain healthy immune system cells and protect against enveloped viruses, take one lozenge daily or two daily for enhanced defense.

Other Ingredients

Maltodextrin, dextrose, fructose, silica, citric acid, natural blueberry flavor, cyclodextrin and magnesium stearate.

This stuff has been amazing for my children and myself. We take it at the first sign of feeling unwell and just for a fews days after and we have not been sick for months. My colleagues at work use it too and I even sent a bottle to my parents. We love it!!

It works for us!

Posted by Reviewer3001153 on Jul 02, 2008

Take it right away if you start to feel sick or have an exposure to someone with a cold or flu. It's kept us healthy. If you take it after you've gotten sick, you can decrease the severity and shorten the duration of the illness.

Both my husband & I suffer from CFS & sinusitus, we actual have noticed a difference when we stop taking Blockade for just a day & feel like we starting to get a cold again. Even though you may still get a virus it definitely helps minimize the effects. This was recommended to me by my GP, who is a very conservative doctor!!!

Healthiest winter yet

Posted by Reviewer1081222 on Apr 20, 2008

Taking one lozenge a day, while exposed to sickness many times this past winter, I went down only once with a sinus infection where my past winters have been marked by repeat occurrences of sore throat, cold and flu.
