Patterns Commonly Discussed
Diets emphasizing whole grains, vegetables, legumes, healthy fats, and moderate protein (broadly Mediterranean-style patterns) are the most-studied dietary patterns in reproductive research and are commonly recommended for general health during fertility planning.
Specific Nutrients
- Folate / folic acid — standard preconception recommendation.
- Vitamin D — deficiency is common and worth checking.
- Iron and B12 — relevant especially in vegetarian/vegan patterns.
- Iodine — thyroid support during preconception.
Weight and Metabolic Health
Extremes of body weight in either direction can affect ovulation and treatment response. Modest, sustainable changes tend to be more useful than aggressive short-term interventions.
Supplements
Marketing claims for fertility supplements frequently outrun the evidence. Discuss any supplement with your clinician, especially before or during a treatment cycle, since some interact with medications.
