Make sure your prenatal vitamin contains iron! Most of the gummy vitamin options I’ve come across don’t contain iron, so check your label. You need 30 mg of elemental iron daily while TTC and during pregnancy.

Folic acid is the recommended form for prenatal supplementation because it has proven efficacy in preventing neural tube defects in large randomized trials, while methylfolate (5-MTHF) lacks this same level of evidence.

Folic acid supplementation is safe and effective even in women with MTHFR variants. The USPSTF explicitly notes that “folic acid consumption may help diminish the effects of the gene mutation” in individuals with MTHFR variants.

Importantly, folic acid is the only folate form with high-quality evidence from randomized controlled trials demonstrating prevention of neural tube defects. A landmark trial showed 72% reduction in NTD recurrence with 4 mg daily folic acid supplementation.

Studies show that 5-MTHF is “at least as effective as folic acid in improving folate status,” but this measures blood levels, not clinical outcomes. The critical distinction is that synthetic folic acid remains the only folate form with proven efficacy in large randomized clinical trials for preventing NTDs. Even individuals with MTHFR polymorphisms respond well to standard folic acid supplementation, as the extra substrate overcomes the reduced enzyme activity.

Geriatric pregnancy? I prefer “advanced maternal age,” but these terms refer to pregnancies in individuals age 35 or older, and they are associated with increased risks.
It’s not like something magical happens at 35 that automatically makes you high risk, it’s more of a continuum, with risks increasing in general as women have pregnancies at ages after the mid twenties. We see the greatest inflection point up towards higher risks at age 40. Preexisting health status is HUGE, so those who are healthier and in better shape with less medical problems or well controlled medical problems, will do better pregnant overall.

Again, if we just paid the people to do the surgeries for the ladies, I think the world of OBGYN and the safety of women would be improved. At present, general OBGYNs are disincentivized from performing surgery — this can lead to excessive referrals to specialists for routine GYN surgery and loss of generalist skills/reps. I shouldn’t make less doing GYN surgery for the day than I would in the office, that’s crazy. But hey, sexism 🎀

THIS is the crux of the issue imo — GYN surgery (and OB andGYN care generally) MUST be reimbursed more fairly moving forward.
