Results from this study1

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In patients with ulcerative colitis in remission, vitamin D3 injection raised the mean fold change of the body's own hCAP18 (LL‑37) gene expression more than placebo.
