Brief Summary

Dysbiosis of gut microbiota has been reported to be involved in the development of hypercholesterolemia in both humans and animal models. Probiotics have been reported to have ameliorative effects in murine models. However, whether probiotics could help alleviate dyslipidemia in adults remain obscure.
