01
B. licheniformis and B. subtilis produce cyclic lipopeptides that disrupt viral lipid envelopes and secrete subtilisin-like proteases that cleave viral surface glycoproteins, providing direct virucidal activity at mucosal surfaces.

The headline result
Up to 42% reduction in acute respiratory infection risk with Vitamin D3 supplementation; combined with 6-strain formula — 90-day use reduced URTI episodes, severity and duration by approximately 50%.
The science
Why Vir Pro works.
Virpro is a high-potency 15 Billion CFU, 6-strain synbiotic engineered for broad-spectrum antiviral protection. It combines two spore-forming Bacillus strains (B. licheniformis and B. subtilis) with four Lactobacillus/Bifidobacterium strains plus Vitamin D3, C, B6, and FOS.
The Bacillus duo produces antiviral lipopeptides (iturin A, surfactin, fengycin) with documented activity against enveloped viruses including influenza, herpes simplex, and coronaviruses. Vitamin D3 stimulates cathelicidin (LL-37) production, reducing acute respiratory infection risk by up to 42%.

Mechanism of action
How it works, step by step.
The documented biological pathway — exactly how each component acts inside the body.
02
Lactobacillus and Bifidobacterium strains activate plasmacytoid dendritic cells via TLR-9 signalling, triggering type-I interferon (IFN-α/β) responses. L. reuteri further reduces viral load by reuterin-mediated inhibition of RNA-dependent RNA polymerase.
