Key Highlights
Broad-Spectrum Antimicrobial Defense
Effectively targets bacteria, viruses, fungi, and biofilms — including antibiotic-resistant strains like MRSA.
Immune System Regulation
Balances inflammatory and anti-inflammatory cytokines, helping the immune system respond effectively without overstimulation.
Promotes Wound Healing
Stimulates angiogenesis (new blood vessel formation) and keratinocyte migration, accelerating recovery in wounds, surgical sites, and damaged tissues.
Supports Gut Health
Strengthens gut barrier integrity and reduces intestinal permeability (“leaky gut”), supporting digestive and immune balance.
Reduces Chronic Inflammation
Helps manage inflammatory conditions by modulating immune signaling, reducing tissue stress, and supporting long-term healing.
Enhances Tissue Regeneration
Encourages regeneration of skin and mucosal tissues, improving recovery from trauma and chronic wounds.

LL-37 FAQs
What does LL-37 do in the body?
LL-37 acts as a natural antimicrobial and healing agent, protecting the body from infection while promoting tissue regeneration and immune balance.
Is LL-37 beneficial for gut health?
Absolutely. It helps maintain a healthy gut barrier, reducing inflammation and preventing “leaky gut” by supporting mucosal repair.
Does LL-37 help with inflammation?
Yes. LL-37 regulates immune activity to reduce chronic inflammation while still supporting proper immune defense.
How is LL-37 administered?
LL-37 is typically available in injectable or topical formulations, depending on whether the goal is systemic immune support or localized healing.
