Preconception Nutrition

What "preconception" actually means.

The preconception window is the 90 days before conception. The time during which egg and sperm cells are developing. Everything you eat, drink, breathe, supplement (and do not supplement) during this window has a measurable effect on the quality of those cells.

Why most prenatals are wrong for this window

Standard prenatal vitamins were designed for pregnancy. For the first and second trimester. They are calibrated for the needs of pregnancy, not the needs of preconception. They typically:

• Use synthetic folic acid, not 5-MTHF active folate
• Use one form of B12 (cyanocobalamin) instead of the two active forms
• Contain no CoQ10
• Use doses calibrated for pregnancy, not preconception

What good preconception nutrition looks like

The research consistently highlights the following nutrients during the 90-day window:

• 5-MTHF folate. The active form, usable by all MTHFR variants. Folate contributes to maternal tissue growth during pregnancy and has a role in cell division.
• B12 (methylcobalamin + adenosylcobalamin). Both active forms support red blood cell formation, energy metabolism, and homocysteine metabolism.
• CoQ10. Involved in mitochondrial energy production. An active research area for both egg and sperm cell quality.
• Vitamin D. Has a role in cell division and normal immune function. Many UK adults are deficient, especially in winter.
• Zinc. Contributes to normal fertility and reproduction.
• Selenium. Contributes to normal spermatogenesis and to normal thyroid function.
• Iodine. Contributes to normal thyroid function, which affects ovulation.
• Choline. Increasingly recognised role in maternal nutrition and infant brain development.

Every one of these is in BioMirco Fertility Advance and Fertility Focus, in active forms and research-backed doses.
