NOW, MORE THAN EVER,
Your Immune System’s Intelligence Matters.
As new challenges to our immune systems continue to arise, the need for a smarter, stronger, and faster-acting defense strategy has never been more important.
Sinus Defense molecules signal your immune system to launch an immediate response when pathogens invade. With continued use, those same molecules teach immune cells to fight future invaders with greater speed and efficiency.


Live your best life by teaching your immune system to disrupt the cycle of sickness.
THE HARD WAY
Traditionally, your immune system learns to respond to invading pathogens once they trigger your body’s alert system and begin causing sickness.
THE SMART WAY
Sinus Defense cuts the learning curve by instructing your immune system to take action immediately and respond to invading pathogens quickly to help prevent or lessen sickness.
“As someone who has been very susceptible to every bug my child brings home from daycare, I can proudly say that since using CitriDrops Nasal Spray and Sinus Defense, I’ve had no illnesses.”
HOW DOES SINUS DEFENSE WORK?
Like an antibody, only faster.
Sinus Defense stimulates your immune system to recognize and tag foreign pathogens quickly, before illness takes root. With regular use, your immune system knows what to watch for and attacks pathogens the smart way, not the hard way.

1.
SINUS DEFENSE CONTAINS IMMUNITY KNOWLEDGE
When you spray Sinus Defense under your tongue, it enters the bloodstream and begins transferring critical immunity knowledge to your T-Cells.

2.
YOUR T-CELLS LEARN FROM SINUS DEFENSE
As your T-Cells “learn” what to look for, they identify invading pathogens much more quickly.

3.
T-CELLS USE KNOWLEDGE TO SPOT PATHOGENS
Armed with new immunity knowledge about invading pathogens, your T-Cells tag pathogens for removal BEFORE the sickness sets in.

4.
WHITE BLOOD CELLS DESTROY INVADING PATHOGENS
Marked for destruction, macrophages (your white blood cells that “eat up” pathogens and debris), swoop in to do the work of eliminating the invaders more effectively.
Give Your Immune System the Best Chance Possible
Your immune system is not bulletproof. Stress hormones and resource depletion can wear it down and cause it to be less effective when pathogens attack.
A Smarter Immune System Doesn’t Have To Work As Hard
As new immune system challenges arise, the need for a smarter, stronger, and faster-acting method of protection has never been more important.
Feeling protected everywhere you go
Sinus Defense teams up with your immune system instantly. You can use it anytime you feel you have been exposed. Right then and there, you can boost your chances of fighting off any potential invasion.
Prepare for the invasion before the battle starts
The age-old adage, "An ounce of prevention is worth a pound of cure," should be at the core of your wellness strategy. Prepare BEFORE you are exposed to pathogens by teaching your immune system what to watch out for.
An immunity map to the shortest path of recovery
When there is a breach and pathogens gain access to replicate and attack your cells, give your immune system the help it needs to find the fastest path to recovery.
What is Transfer Factor?
“The immune-system advancing ingredient in Sinus Defense is Transfer Factor. Transfer Factor is a molecule that acts like an antibody but is smaller. It gets its name because it ‘transfers’ cell-mediated immunity directly to white blood cells.
Transfer Factor molecules are able to impart immunity to specific, targeted pathogens and have been used successfully to enhance the immune response or as primary therapy for a number of viral, parasitic, fungal, and bacterial infections.
Transfer Factor molecules also seem to have a ‘black box’ effect because as the immune system gets better and more robust, this promotes cell-mediated immunity to new pathogens that may enter the body. It is as if learning how to defend against one pathogen lessens the learning curve with new ones. This is what gives Sinus Defense preventative potential."

The Research...
"Transfer Factors are not only useful for disease prevention but can also help with diseases already established due to inadequate immune response. Since Transfer Factors-producing T-lymphocytes are important in immune recognition and memory, impairment of Transfer Factors production could neutralize the rest of the immune response in otherwise healthy individuals."
Greg B. Wilson, Ph.D. and James B. Daily, Jr., Ph.D.
