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.

  1. 01HumanEndogenous levelRandomized controlled trialEfficacy outcome

    In weaned infants with anemia, formula with 76 mg/100 g bovine lactoferrin raised fecal LL‑37 levels more than formula with 0 or 38 mg/100 g after 3 months.

    In plain wordsIn infants with anemia, the highest lactoferrin dose in formula raised the body's own LL‑37 in stool more than the lower doses.

    Summary
    The HBD-2, LL-37, sIgA, and calprotectin levels were significantly higher whereas the butyrate level was significantly lower in the FG2 infants than in infants in the other two groups after 3 mo of intervention (P < 0.05).

    Summary · context
    The eligible infants were randomly assigned to fortified group 0 (FG0), fortified group 1 (FG1), or fortified group 2 (FG2) and were given formula fortified with 0 mg/100 g, 38 mg/100 g, and 76 mg/100 g of bLF, respectively, for 3 mo.
    Summary · context
    The morbidity of diarrhea and respiratory tract infections (RTIs), the duration of respiratory and diarrhea-related illnesses, and the levels of fecal human beta-defensin 2 (HBD-2), cathelicidin LL-37 (LL-37), secretory IgA (sIgA), butyrate, and calprotectin were assessed.

    This result measures the body's own LL-37. Nobody was given the peptide. It is not evidence about taking it.
