Which vitamins matter when trying to conceive?
Answered by the AskDoc Medical Team · Medically reviewed under our Medical Director, MBBS
One is non-negotiable: folic acid, 400 micrograms daily, started at least a month before trying, cuts serious spinal birth defects dramatically. It is the single best-evidenced supplement in all of medicine for this moment.
Vitamin D if yours is low, and iodine adequacy matter; a basic prenatal vitamin covers both. Correct iron only if tests show deficiency.
Expensive fertility blends add marketing, not conception. The bigger levers remain smoking cessation for both partners, moderate weight, limited alcohol, and timing sex to the fertile window.
