The 2QR-complex is a novel and patented ingredient that consists of natural polysaccharides. It has the unique ability to neutralize harmful microbes by physically blocking their adhesion. This mode of action is selective and does not affect the desired flora. That is why the 2QR-complex is highly effective in correcting and restoring the micro flora. It directly solves a wide range of problems related to bacterial overgrowth, without any adverse effects. This makes the 2QR-complex the ideal basis for a variety of self-care and OTC-products.
