Sinus Defense
Sinus Defense


Sinus Defense sublingual spray delivers bioavailable Transfer Factor to immune system cells, aiding the body’s natural ability to identify, mark,  eliminate, and remember foreign invaders, like mold, allergens, and viruses.

Sinus Defense is a homeopathic, colostrum-based supplement containing Transfer Factor, small immune messenger molecules that help cells identify and eliminate invaders. Once Transfer Factor targets mold invaders, immune cells (T Cells) become efficient destroyers of it. Sinus Defense is designed to bind to a broad array of antigens, especially mold, since mold spores exist almost everywhere, to reduce inflammation and other symptoms normally caused by mold exposure.

Apply 2-3 sprays of Sinus Defense under the tongue 2-3 times daily. Adjust number of sprays and applications as needed.

Children under 12: Consult a Health Care Professional prior to use. Bottle lasts for 6-8 weeks depending on number of sprays used. NOTE: Sinus Defense does not require physician allergy testing and administration. It can be used prior to or in conjunction with allergy shots or immunotherapy, where specific antigens are introduced to the body, enabling it to develop antibodies over time (several weeks). Sinus defense begins to target antigens immediately to take advantage of our immediate natural T cell immunity.

  • Blood Test Proof

    Posted by Richard Appel


    I have monitored the antibody reaction to mold for years through IgG blood tests. I have tried all kinds of remedies to help with my fungal allergy reaction. The only thing that I have ever used that has reduced all 5 IgG levels is Sinus Dense. It is now apart of my daily routine and I feel so much better.

  • I've had no illnesses

    Posted by Michael Parsons


    As someone who has been very susceptible to every bug my child brings home from daycare, I can proudly say that since using Citri Drops and Sinus Defense, I've had no illnesses; while others in my home have experienced significant colds, sinusitis and even strep.

  • I think its working

    Posted by Cindy Canoy


    I have used this for almost a year and still use it 2X a day with 9 sprays each time. I don’t necessarily see immediate results but I hope it’s making a difference in my immune system. I wish it were not so expensive.

  • I am 50 to 60% better and can sleep at night

    This stuff works. I have suffered for years with chronic sinus problems. Nothing I have tried has cleared up my post nasal drip. In just 3 weeks of using the nasal wash, CitriDrops Nasal Spray, and now Sinus Defense I am 50 to 60% better and can sleep at night.
