BioBlock® nasal spray


BioBlock® nasal spray


BioBlock® nasal spray is a natural product that contains antibodies against SARS-CoV-2 along with naturally occurring beneficial antibodies in colostrum which humans benefit daily while consuming dairy and meat products. In vitro testings demonstrated that the product blocks the entry of viral particles into cells.
Tests were performed against initial Wuhan and newly mutated SARS-CoV-2 variants  – Omicron B.1.1.529 (incl. its sublineages BA.1, BA.2, BA.4, BA.5, BA.2.75.2, BA.2.3.20, BQ.1.1, XBB.1.5), Indian (Delta B.1.617.2, Kappa B.1.617.1), UK B.1.1.7, South African B.1.351 and Brazil P.1.

BioBlock® can be used wherever it is difficult to distance from others: at home, at work, at school, in gyms, in public transportation and in crowded places. This natural product does not cause dryness of nasal mucous membrane.

BioBlock® is not a medicine.


2 sprays into each nostril, 3-4 times a day, and before and after visiting crowded places. After blowing the nose, it is recommended to use the spray again.

BioBlock® is effective on the nasal mucosa up to 4 hours.

The product contains 150 spray doses.


Does BioBlock affect the SARS-CoV-2 test results?

No. PCR tests identify genetic material of the virus and antigen tests identify proteins of the virus. BioBlock does not contain any of them.  In case of antibody testing after a  person has had Covid-19 disease, blood sample is analyzed for human anti SARS-CoV-2 antibodies. BioBlock contains bovin antibodies.

Does BioBlock have any side-effects?
All ingredients are safe and carefully chosen, which are specifically meant for use on nasal mucus. If a person does not use spray products in general, there might occur slight irritation.
There are no side-effects to our knowledge. However, persons who have milk protein allergies (e.g. to casein) should not use the product. BioBlock is lactose free.

Is it safe for children?
It is more frequent that milk protein allergy occurs in children rather than adults (especially children under 6 years of age), so it is recommended to consult with your healthcare professional. In any other cases, BioBlock is safe for children.

Is there a fixed time period for how long a person can use the product?
No, there is not. BioBlock can be used consistently.

Does BioBlock dry nasal mucus?
No, BioBlock solution has moisturizing properties.

Can it be used with other products/medicines/preparations?
There are no contraindications to our knowledge.

Why is the natural bovine colostrum more preferred?
Bovine colostrum contains ca 150 times more antibodies than ordinary milk. The concept of BioBlock is related to SARS-CoV-2 antibodies which are not found in ordinary milk.

What is the efficacy of BioBlock.
We have proven in-vitro results, with 99% of efficacy. Additional clinical trial is getting started.

Should i wear a mask after I have sprayed BioBlock into nose?
Yes. BioBlock is an additional precautionary measure which together with masks and vaccines helps to prevent the spread of the virus. BioBlock does not replace masks.

What does it taste like?
BioBlock has a slightly salty taste because of the buffer salts, which are meant for preservation of antibodies.

Does BioBlock cure me faster, if I already have Covid-19 disease?
Final clinical trials will answer the question, although it is possible considering in-vitro testing results.

Is BioBlock addictive?
No. We confirm that BioBlock has no well-known addictive ingredients in it.
