Peptides
LL-37 (Defense / Immune Support)
Broad-spectrum defense. Support your innate immunity.
Your body already makes its own front-line defenders. LL-37 is one of them. It is a human-derived antimicrobial peptide — a short chain of amino acids that acts as a broad-spectrum defense mechanism.
People turn to LL-37 for immune support. It targets a wide range of pathogens, including bacteria, viruses, and fungi, and it breaks down biofilms — the protective layers microbes build to shield themselves. At the same time, it calls white blood cells to where they are needed and helps keep inflammation from running unchecked.
There is a repair side too. LL-37 supports wound healing and tissue regeneration by encouraging angiogenesis, the growth of new blood vessels that bring more blood flow to damaged areas. It is also studied for its role in supporting the gut barrier.
At IAM, LL-37 is supplied as an injectable vial. A licensed provider reviews your history first and builds a plan around your goals.

How it works
LL-37 is a human-derived antimicrobial peptide — a short chain of amino acids your own body makes. It acts as a broad-spectrum defense, targeting pathogens and breaking down biofilms while attracting white blood cells to sites of infection. It also supports gut health, calms unnecessary inflammation, and promotes tissue regeneration through angiogenesis — the growth of new blood vessels that carry more blood to healing tissue.
Who it's for
LL-37 may fit patients seeking broad immune support, people managing chronic inflammation, those supporting gut barrier integrity, and patients focused on tissue repair. A licensed provider reviews your health history to confirm it makes sense for you.
