Gut Health & Immunity Peptides

Gut-health and immunity peptides act on inflammation and host defense through several distinct pathways. KPV is an anti-inflammatory tripeptide derived from α-MSH, often paired with BPC-157 for combined gut and tissue-repair effects; LL-37 is an antimicrobial and immunomodulatory peptide naturally produced by the human immune system; Thymosin Alpha-1 works through broader immune modulation. VIP (vasoactive intestinal peptide) acts on the VPAC1/VPAC2 receptors for vasodilation and immunomodulation among these 5 entries, and its synthetic form aviptadil remains investigational rather than FDA-approved.
