Female Fertility & TTC

For anyone trying to conceive, one supplement is non-negotiable (folate, for the baby), and a few others — inositol, CoQ10 — have a reasonable rationale for egg quality and ovulation. But the honest headline is that large umbrella reviews find the evidence that "fertility supplements" raise conception or live-birth rates is limited and low-quality (and drawn mostly from women in IVF/fertility treatment, not spontaneous conception). Here’s what’s genuinely worth taking, what’s hopeful-but-unproven, and how this differs from our PCOS guide.

Last reviewed Jun 24, 2026 · Evidence-based — every ingredient links to its underlying studies.

Start folate, and get a fertility work-up if it’s taking a while

Start a folate/prenatal before conception (neural-tube-defect prevention is proven). If you’ve been trying ~12 months (or 6 if over 35), see a doctor — many causes (ovulatory, tubal, thyroid, male-factor) need medical evaluation, not supplements. For PCOS-specific metabolic support, see our PCOS guide; this guide is about preconception/egg-quality.

At a glance
Do
  • Take folate/methylfolate before conception (essential)
  • Consider inositol if you have irregular/PCOS cycles
  • Get a work-up after ~12 months trying (6 if 35+)
Skip / caution
  • Expect "fertility blends" to overcome a medical cause
  • Take high-dose preformed vitamin A (retinol) or untested herbs while TTC
  • Assume supplements replace a fertility evaluation

Key point: Folate is essential; inositol and CoQ10 are the best-supported extras — but proof they raise conception/live-birth rates is limited.

Honest expectations

The one supplement with rock-solid TTC evidence is folate — and that’s to protect the baby, not to boost conception. For conception itself, inositol (in the 40:1 myo:D-chiro form) genuinely helps ovulation in insulin-resistant/PCOS cycles, and CoQ10 is a reasonable bet for egg quality with advancing age — but a Cochrane/umbrella read of "fertility supplements for sub-fertile women" concludes the evidence for higher live-birth or pregnancy rates is limited and low-quality. So take folate, consider inositol/CoQ10 if they fit your situation, avoid high-dose preformed vitamin A (retinol) and untested herbs, and don’t let supplements delay a proper work-up if conception is taking time.

Common questions

What supplements help with fertility / TTC?

Folate is essential before conception (for the baby). For conception itself, inositol helps insulin-resistant/PCOS cycles and CoQ10 is studied for egg quality — but the evidence that fertility supplements raise conception or live-birth rates is limited (and mostly from IVF/treatment settings).

Does CoQ10 improve egg quality?

It’s a reasonable, mechanistically sensible bet — especially with age or diminished ovarian reserve — and early trials are encouraging, but it’s not conclusively proven to increase pregnancies.

Is inositol good for getting pregnant?

For women with PCOS or insulin resistance, the myo + D-chiro (40:1) combination improves ovulation and is a solid option. Use the 40:1 ratio — high-dose D-chiro-inositol alone can impair egg quality.

When should we see a doctor?

After about 12 months of trying (6 if you’re over 35), or sooner with known issues. Many fertility causes need medical evaluation and treatment that supplements can’t address.
