A 2025 meta-analysis of randomized controlled trials found that GLP-1 medications significantly reduced fasting insulin, post-glucose-tolerance-test glucose, and HOMA-IR, a standard insulin resistance measure, in women with chronic anovulation and insulin resistance, alongside reductions in BMI and waist circumference. The same research found significantly increased rates of nausea, vomiting, and dizziness. Longer-term data on glucose and lipid outcomes in this population is still limited, and researchers are explicit that more study is needed before drawing firm conclusions.

GLP-1 medications reduce caloric intake by an estimated 16 to 39 percent, and months of reduced eating can leave nutrient stores, including folate, thinner than you'd expect once you start actively trying to conceive. The conversation around stopping a GLP-1 tends to focus on the medication itself, not on what months of appetite suppression may have done to your nutrient reserves. Folate deserves specific attention because it plays a role in ovulation, implantation, and early pregnancy, all of which matter in the preconception window.

Recent OB/GYN guidance recommends structured preconception counseling for women on GLP-1 medications, rather than a blanket "just stop" approach. It centers on timing discontinuation to the medication's half-life, using proven alternatives like metformin and lifestyle changes once you are actively trying to conceive, and following up with your provider throughout the process. Current data have not shown a clear increase in birth differences from unintended early exposure, but the evidence is still limited and observational, so this is a "plan ahead" conversation, not a "don't worry about it" one.

Clinical research comparing different ratios of myo-inositol to D-chiro-inositol found that a 40:1 ratio was the most effective for restoring ovulation and normalizing key hormone markers, while formulas with too much D-chiro-inositol relative to myo-inositol actually performed worse.^† This is one of the more specific, checkable details worth knowing before choosing an inositol supplement, since ratio is not something every bottle discloses clearly.

Methylated folate (5-MTHF) is the active form of folate that your body can use directly, without needing to convert it first, which matters because folate plays a critical role in fetal neural tube development in early pregnancy.^† Some people have a genetic variation called MTHFR that affects how efficiently they convert standard folic acid, but the CDC notes that people with this variation can still process all types of folate, so this is about knowing what to look for on a label, not something everyone needs to test for¹.

Ginger and vitamin B6 are the two options with the strongest head-to-head research behind them for nausea and vomiting of pregnancy, and multiple randomized trials have found they perform similarly well. Always consult your healthcare provider before starting any new supplement, especially during pregnancy. A large trial found ginger and vitamin B6 to be equivalent for reducing nausea, retching, and vomiting, so the more useful question is often which one fits your routine, not which one is objectively better.^†
