Antimicrobial Peptide

LL-37
The human cathelicidin antimicrobial peptide

Starting at $295

LL-37 is the only member of the cathelicidin family in humans — a natural antimicrobial peptide produced by immune cells, skin cells, and mucosal epithelia as the body's first line of defense. It has direct antibacterial, antifungal, antiviral, and immune-modulatory properties, with emerging applications in wound healing, skin conditions, and immune optimization.

LL-37 peptide therapy

Natural antimicrobial defense restored.

1

Antimicrobial Activity

Membrane Disruption

LL-37 disrupts bacterial and fungal cell membranes through amphipathic helix insertion — a mechanism resistant to the development of antibiotic resistance. Effective against antibiotic-resistant organisms.

Result: Broad-spectrum antimicrobial activity including drug-resistant organisms

2

Innate Immunity

Immune Activation

Acts as an alarmin — activating dendritic cells, mast cells, and macrophages to mount coordinated immune responses. Bridges innate and adaptive immunity.

Result: Enhanced innate immune response coordination

3

Tissue Repair

Wound Healing

Promotes wound healing through multiple mechanisms: chemotaxis of immune and repair cells, angiogenesis, and epithelial cell migration and proliferation.

Result: Accelerated wound closure and reduced infection risk

Clinical Benefits

What you can expect from LL-37 therapy

Antimicrobial activity

Direct activity against bacteria, fungi, and viruses — including antibiotic-resistant organisms like MRSA.

Wound healing

Accelerates wound closure through immune cell recruitment, angiogenesis, and epithelial repair.

Skin health

Deficiency in LL-37 is implicated in atopic dermatitis — topical supplementation supports skin barrier defense.

Antiviral protection

Demonstrated activity against multiple viruses including herpes simplex, influenza, and SARS-CoV-2.

Immune bridge

Connects innate and adaptive immunity, ensuring coordinated and comprehensive immune responses.

Neuroprotection

Emerging evidence for LL-37 in reducing neuroinflammation and supporting neuroprotective pathways.

The Process

2

Weeks 1–3

Immune Activation

Enhanced innate immune response. Wound healing accelerates with improved cell recruitment.

3

Weeks 3–6

Tissue Repair

Structural wound healing and skin repair complete. Chronic conditions show progressive improvement.
