Quick Answer
Heat-Killed Probiotic Sleep Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: 1 2 3 4 5 4 The term ‘postbiotic’ has found its way into the vocabulary of scientists and increasingly also of consumers.

- The gut-immune-metabolic axis has emerged as a central regulator of human health, with growing evidence indicating that microbiota-derived metabolites improve gut microbial ecology, enhance intestinal barrier integrity, reduce systemic inflammation, and maintain metabolic homeostasis.

Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
