The effect of postbiotics on depressive symptoms and polycystic ovary syndrome (PCOS) in human health: A short review

Postbiotics are known as preparations comprising inert microorganisms and/or their ingredients that activate health profits on the host. They motivate the intestine microbiome and back the gut immune activity and prevent the duplication of pathogenic microorganisms as well. Although postbiotics are a type of probiotic waste, they can apply some beneficial effects on human health such as anti-obesity, antioxidant, immunomodulatory, and anti-carcinogenic. Accordingly, many studies suggested a conclusive effect of postbiotics on polycystic ovary syndrome (PCOS) in women and depressive symptomatology. The aim of our study was to provide an updated review of these subjects. We conducted a systematic search of literature in multiple databases such as Web of Science, Google Scholar, Science Direct, and PubMed based on some keywords. In the current review, we have focused on an effective, better understanding of postbiotics on consumers’ health and present a base for future investigation.
