Our mission is simple - to help as much people as possible to improve their overall health!

bioquant mission





We developed a medical device that has better light properties than any other device on the market intended for blood irradiation through nasal cavity. 


Because we know how great effect the light has on human cells! And our patented nasal applicator provides the light quality and properties we are proud of. 

If every family had one medical device for blood irradiation for all members to share, the world would become better place to live. Because a prevention against cardiovascular and cerebrovascular diseases is better than treatment.
