Fertility & Preconception — The Nutrient Foundation Most Doctors Skip
What your body actually needs before conception. MTHFR and methylated folate, egg quality nutrients, uterine lining support, and the lab panel worth runnin
Key Findings
- MTHFR variants affect 40-60% of people and reduce folic acid conversion by 30-70% — methylfolate is the safer choice regardless of MTHFR status
- CoQ10 as Ubiquinol (600mg/day starting 3 months before conception) is the most research-backed nutrient for egg quality
- Ferritin below 70 ng/mL impairs uterine lining even when hemoglobin appears normal
- TSH above 2.5 is associated with impaired fertility — most OBs only flag above 4.5
- Sperm takes 74 days to mature — male partner nutritional changes need 3+ months lead time

The Bottom Line
Start 3-6 months before conception with methylated folate, CoQ10 as Ubiquinol, Vitamin D, and iron (to ferritin target) — and run a full thyroid panel including TSH, Free T3, and TPO antibodies. Most fertility gaps are nutritional and addressable before you start trying.
