Be sick smarter. Recover faster & protect others.
Seasonal respiratory viruses are unavoidable. Help your body fight where it matters most, at the site of infection, with Colver nasal spray. The first product designed to support local immunity in the lining of your nose and throat.

Our Mission
Empowering health-conscious individuals to address the root cause of upper respiratory infections instead of just temporary relieving their symptoms.
Most common cold viruses replicate in the nasopharynx region of the nasal cavity. Unlike oral supplements, Colver nasal spray is designed to target and strengthen the natural immune response directly at the site of infection.

Use up to 3x/day at the first sign of symptoms
See FAQ page for complete formulation
Protect others without changing your habits
