Planning for pregnancy or navigating your fertility journey? The right nutrition can make all the difference. Vitamins and minerals play a key role in balancing hormones, improving egg quality, and supporting your baby’s healthy development from the very start. While a well-rounded diet is the best way to get these essential nutrients, knowing which ones to focus on can help you optimize your fertility and prepare your body for a healthy pregnancy. Let’s explore the most important vitamins and minerals, their benefits, and how to incorporate them into your daily routine.

Additional supplements for fertility

Some supplements, like DHEA and Alpha Lipoic Acid, have shown potential benefits but require further research.

  • Inositol: Supports ovarian function, cycle regulation, and insulin sensitivity (recommended for PCOS patients). 
  • CoQ10: Aids in egg and sperm quality, especially for those with diminished ovarian reserve (DOR). 
  • N-Acetyl-Cysteine (NAC): Helps reduce oxidative stress and inflammation, particularly for those with PCOS and endometriosis. 
  • Alpha Lipoic Acid (ALA): Supports insulin sensitivity and sperm quality, though data on female fertility is limited. 
  • DHEA: May improve antral follicle count in women with low ovarian reserve but lacks conclusive evidence on pregnancy outcomes. 

Choosing the right prenatal vitamin

While a balanced diet is the best way to obtain essential nutrients, a high-quality prenatal vitamin ensures you meet your daily requirements. Look for a prenatal supplement that includes iron, choline, DHA, and calcium, as many standard formulations may fall short. 

Recommended brands: 

  • Theralogix 
  • One a Day Prenatal Advanced with Choline 
  • Nature Made Prenatal with DHA 
  • Zahler (kosher, gluten-free) 

The journey to parenthood begins with a strong foundation, and proper nutrition is one of the most powerful tools at your disposal. By prioritizing a diet rich in essential vitamins and minerals—and supplementing wisely—you can support your fertility, promote a healthy pregnancy, and set your baby up for the best possible start in life. Remember, every individual’s needs are unique, so before making any changes to your supplement routine, consult with your doctor or fertility specialist to ensure you’re giving your body exactly what it needs.
