Antimicrobial Blue Light Targets Viral Infections

Antimicrobial blue light (aBL) therapy is an innovative, drug-free approach that uses specific wavelengths of light (typically 405–470 nm) to help inactivate a wide variety of infectious agents including bacteria, fungi and viruses. Enveloped viruses like CoVID-19 are particularly susceptible to aBL:

How aBL Works

In addition to directly targeting microbes, aBL helps prime the innate immune system, which serves as the body’s initial barrier against infection.

Direct Attack on Viruses

Both photodynamic therapy (PDT) and antimicrobial blue light (aBL) eliminate infectious agents by generating reactive oxygen species (ROS). PDT achieves this by applying an external photosensitizer and activating it with light of a specific wavelength. In contrast, aBL relies on activating natural, endogenous photosensitizers produced by the pathogen itself. The resulting ROS act quickly and at multiple levels to interfere with viral entry, function, and replication. The resulting ROS act quickly and at multiple levels to interfere with viral entry, function, and replication. Furthermore, antimicrobial resistance has not been observed with aBL or PDT, likely due to the rapid and multi-targeted action of ROS in eliminating pathogens.

Enhanced Immune Response

In addition to its direct antimicrobial effects, aBL helps prime the innate immune system, which serves as the body’s initial barrier against infection.

Why It Matters

Newer strains of CoVID-19 not only show increased resistance to antibody-mediated defenses but further mutations have resulted in suppression of innate responses, including critically important interferon production. aBL is active against all CoVID-19 variants and other viruses - and enhances this compromised innate immune response.

Treatment Options

1. Local aBL Treatment

Blue light is applied to the nose, mouth, and over closed eyes to reduce the chance or severity of infection by lowering the viral load at points of entry.

2. Sublingual Blue Light

Light directed under the tongue reaches blood vessels directly, allowing systemic (whole-body) effects. This method is useful for more advanced infections.

3. Combination Therapies

aBL can be combined with oral riboflavin (vitamin B2) for enhanced antiviral effects (Photodynamic Therapy) or with red light for healing and inflammation support (Photobiomodulation).

Advantages of aBL

Although its effects can be enhanced with the addition of a photosensitizer, the beauty of this approach is that it can be used as a standalone treatment without the need to source other treatment supplies:
