Four weeks of oral supplementation with Lactobacillus acidophilus NCFM preserves insulin sensitivity in subjects with normal glucose tolerance, impaired glucose tolerance, or type 2 diabetes compared to placebo, without affecting systemic inflammatory markers.

Taking 1 gram of Lactobacillus acidophilus NCFM daily for four weeks may help maintain insulin sensitivity in individuals with normal glucose tolerance, impaired glucose tolerance, or type 2 diabetes. This benefit occurs independently of changes in systemic inflammation, suggesting the mechanism is specific to this strain and not a general anti-inflammatory effect of probiotics.

In conclusion, intake of L. acidophilus NCFM for 4 weeks preserved insulin sensitivity compared with placebo, but did not affect the systemic inflammatory response.

Why this rating

Double-blinded, randomized, placebo-controlled trial in humans with rigorous measurement (hyperinsulinemic-euglycaemic clamps), though the sample size is moderate (n=45) and the effect on inflammation was null.
