Nutrition & fertility — education
General fertility-friendly nutrition mirrors public-health eating: adequate energy, folate-rich foods, iron status, omega-3–containing fish where appropriate, and limited alcohol. Supplements should follow clinician advice, not influencer stacks.
Energy availability
Chronic undereating relative to training load (relative energy deficiency in sport, RED-S) can disrupt ovulation. Sports medicine teams address this with staged fueling plans.
Folate and neural tube defects
- Periconceptional folic acid supplementation is widely recommended in public-health guidelines where neural tube defects are a concern.
- Food sources include leafy greens, legumes, and fortified grains.
Caffeine and alcohol
Moderate caffeine is generally discussed as compatible with conception for many; alcohol policies differ by country—follow your clinician during preconception and pregnancy.
