Peptides studied for immune support

Immune-modulating peptides studied for defence, resilience and immune calibration.

1

Thymosin Alpha-1

Immune modulator

Backed by 30+ RCTs; approved in 35+ countries for chronic hepatitis B and used for immune restoration.

2

LL-37

Cathelicidin peptide

Core innate-immune effector: kills microbes, neutralises LPS and recruits immune cells.

3

TB-500

Thymosin Beta-4 fragment

Thymic origin with some immune-modulating activity, but evidence here is thin.

4

KPV

Alpha-MSH tripeptide

Calms overactive immune/inflammatory signalling rather than broadly stimulating immunity.

5

MOTS-c

Mitochondrial peptide

Metabolic/AMPK signalling links to inflammation, but human data are sparse.

6

Selank

Anxiolytic peptide

Derived from immunomodulatory tuftsin, with reported effects on cytokine regulation.
