Gut Bacteria Transplants Offer Sleep Gains in Small Insomnia Trial
In a small study, adults with chronic insomnia received fecal microbiota transplant capsules after a two‑day course of antibiotics. Sleep efficiency rose from about 79% to 93% after one month, and time awake at night dropped from 79 to 17 minutes; self-reported sleep improvements persisted for months. The placebo group saw little change, but antibiotics and the small sample size mean it’s unclear how much of the effect is due to the transplants, underscoring the need for larger trials.
