PN5
THE MICROBIAL FIGHTER
Pine Needle-Derived Antimicrobial Peptide
PN5 is an antimicrobial peptide derived from pine needles that can kill bacteria, including drug-resistant strains, without creating resistance. It works by punching holes in bacterial membranes and preventing biofilm formation. It also has anti-inflammatory effects, making it promising for gut infections, sepsis prevention, and chronic inflammatory conditions.
