Navigating PCOS can feel overwhelming, especially when fertility is part of the picture. Many women tell me they feel stuck between wanting evidence-based answers and wanting options that feel supportive rather than extreme. One supplement that comes up again and again in conversations around PCOS and fertility is N-Acetyl Cysteine (NAC).

If you've been living with PCOS for any length of time, you've probably come across the word "inositol" at some point — scrawled in a TikTok comment, buried in a Reddit thread at midnight, or mentioned by a naturopath when your GP had nothing new to offer.

If you have PCOS and you're pregnant, or trying to become pregnant, chances are nobody sat you down and explained what insulin resistance actually does to your body during this stage. You were probably told to "watch your diet" or handed a glucose tolerance test appointment without much context.

If you've been navigating a PCOS diagnosis and trying to conceive, you've probably come across myo-inositol at some point. Maybe a friend mentioned it, or you found it at the bottom of a TikTok rabbit hole at midnight. Either way, you're right to be curious — because the research on this is actually pretty clear, and it's one of the few supplements in the fertility space that has genuinely earned its reputation.
