ColdZyme® reduces cold duration and symptoms
A scientific article published in the The Journal of Physiology, confirms that ColdZyme not only alleviates cold symptoms but can also reduce the number of sick days. The article is a collaboration between the University of Kent, the Ignaz Semmelweis Institute, and Vetmeduni Vienna.
The evidence behind ColdZyme®
The latest independent study shows that ColdZyme shortens illness duration, alleviates symptoms, and reduces viral loads in upper respiratory tract infections. ColdZyme addresses the underlying cause of upper respiratory infections by physically inhibiting the virus's spread and protecting the cells in the airways. The results reinforce ColdZyme’s position as an effective support for fighting the cause of colds, both for athletes and the general public.
Key results from the study
- Shorter illness duration: The duration of respiratory infections was on average 40% shorter with ColdZyme.
- Reduced symptoms: Study participants who used ColdZyme experienced significantly fewer cold symptoms.
- Reduced viral load: Median amount of virus was reduced by 94 percent.
ColdZyme® helps you beat every cold faster
ColdZyme is a medical device that helps your body clear cold viruses effectively. Use ColdZyme at the first signs of a cold to shorten the duration of your illness and reduce symptom severity.
How ColdZyme® Works
At the first signs of cold- or flu-like symptoms, spray ColdZyme towards your throat, targeting the back of the mouth. ColdZyme forms an osmotically active protective layer that traps and inactivates viruses. This prevents them from infecting and spreading further into the body. As a result, you experience milder symptoms and a shorter cold.

Benefits of Using ColdZyme®
- Shorter colds: When you use ColdZyme at the first signs of a cold, you can shorten the course of the illness.
- Milder symptoms: ColdZyme traps and inactivates viruses in the mouth and throat, reducing viral load. Clinical studies of ColdZyme confirm that this leads to milder symtoms.
- Regain control: With ColdZyme, you take an active step to give your body the best conditions to beat colds faster.

Scientifically proven
ColdZyme has been developed based on research into how respiratory infections occur and how they can be prevented at an early stage. The principle behind ColdZyme is purely mechanical — an additional moisture layer in the throat prevents viruses from attaching to the mucous membrane. The viruses are trapped and inactivated, thereby reducing viral load. The result is milder symptoms and a shorter illness duration — an effect scientifically proven in clinical studies.

Fewer sick days benefit society
Shorter colds — could that also be an advantage for society? Yes, reduced illness not only benefits individuals but can also generate economic gains for society as a whole.
A reduction of just one sick day per person would save society an estimated SEK 1.4 billion per year. The fewer sick days, the greater the potential savings. This calculation is based on 10% of Sweden’s 4.7 million full-time working adults.1
