Nutrition for Fertility, Pregnancy, and Menopause

Episode #98: March 19th, 2026
in THIS EPISODE
Dietitian Ayla Barmmer helps us understand just how much nutrition and gut health impact fertility, pregnancy, and reproductive health during perimenopause and menopause.
While supporting women undergoing IVF, Ayla noticed a troubling pattern: Many were advised by doctors to restrict food, and meet their nutrition needs with prenatal supplements that didn’t prepare their bodies for healthy conception and pregnancy. Furthermore, the medical establishment was hardly addressing men’s pre-conception health at all.
These gaps prompted Ayla to revolutionize reproductive supplements for women and men. She developed a prenatal multivitamin and launched FullWell, offering the first dietitian-formulated product in the category. Her commitment to radical transparency—publishing actual third-party test results rather than relying on certifications—redefined expectations in the supplement industry.
Ayla walks us through how to care for our reproductive health at all phases of life. We go over key labs and pre-conception food and lifestyle strategies for both women and men. And get the non-negotiable nutrition requirements for healthy pregnancy. From there we discuss recovery after birth (often ignored), other postpartum needs, plus recommendations for breastfeeding, and preparation for subsequent pregnancies.
Moving on to priorities in perimenopause and menopause, Ayla cuts through the confusion about protein, collagen, creatine, and enzymes. She red flags various supplements, then gives us a quick course in reading labels and speaking to companies, to ensure we’re giving ourselves the best support.
Big takeaway: Reproductive health goes beyond conception and pregnancy. Paying attention to this part of our health at every age is preventative wellness.
