Core Tip
Core Tip: Higher vitamins A, D, E, K, and B12 levels were casually related to a reduced risk of polycystic ovary syndrome (PCOS) or main pathways implicated in its development, as suggested by our Mendelian randomization investigation. More prospective and functional in vivo and in vitro trials are required to clarify the role of vitamin supplements in the onset of PCOS and main pathways implicated in its development.
