LL-37 may initially trigger a “die-off” or cytokine response as the immune system becomes more active—especially in individuals with autoimmune or inflammatory conditions. This temporary reaction can include fatigue, body aches, low-grade fever, or a flare in symptoms.
We recommend starting slowly and assessing tolerance. These effects are typically short-lived and a sign that the body is beginning to clear underlying infection or inflammation. Always consult your provider if symptoms are concerning or persistent.
LL-37 is a powerful peptide naturally found in the human body as part of your first line of defense against illness and injury. Now available as a prescription therapy, LL-37 is gaining attention for its ability to support the immune system, reduce inflammation, and promote healing in a variety of health conditions.
Whether you're struggling with a chronic infection, dealing with an autoimmune condition, recovering from illness, or simply looking to support your immune health, LL-37 can offer meaningful benefits.
How It Works:
LL-37 is part of a family of molecules called antimicrobial peptides. These peptides not only fight harmful bacteria, viruses, and fungi, but also help regulate the immune system so it responds appropriately—not too weak, and not overly aggressive like in autoimmune conditions.
What LL-37 May Help With:
Immune Support: Helps your body defend against infections, including antibiotic-resistant bacteria
Chronic Infections & Inflammation: Supports recovery from recurring illness, Lyme disease, mold exposure, and more
Autoimmune Conditions: Modulates the immune system to help calm overactive immune responses
Wound Healing & Tissue Repair: Promotes faster healing of skin, soft tissue, and internal inflammation
General Wellness: May benefit those looking to strengthen immune resilience, especially during periods of stress or recovery
LL-37 is being used by people looking for a targeted way to reduce inflammation, enhance healing, and support immune balance—especially when other treatments have fallen short.
