THE GOLD FROM THIS EPISODE

“Our reproductive health signals to us about our overall health at every stage of life.”

“Improving digestive and metabolic health, blood sugar regulation and insulin sensitivity profoundly improves reproductive health and cycle regularity for women.”

“Digestive and liver health are critical for hormone health. Your quality of your nutrition and the diversity of your gut microbiome play a key role in estrogen metabolism.”

“A diet rich in produce, olive oil, eggs, nuts, seeds, beans, legumes, and leaner meats are important for reproductive health at any age.”

“The nutrition and lifestyle choices women and men make three months prior to conceiving is critical for the health of the pregnancy, and the long-term health of mom and baby.”

“Vitamin D has a profound effect on the reproductive system. Get your levels to a healthy place prior to conceiving, and keep them up through pregnancy and postpartum, and also during perimenopause and menopause.”

“Our circadian rhythm influences hormone production and secretion, insulin sensitivity, sleep quality, and digestion. Cultivate consistent meal times, bedtime, and wake times, and get outside for light exposure in the morning. The body loves predictability.”

“Men’s reproductive health matters. Semen quality has a larger impact on the development of the placenta than the health of the woman. Pregnancy risks such as preterm birth, preeclampsia, and gestational diabetes can be traced back to the man's pre-conception health.”

Ayla Barmmer, MS, RD, LDN

Registered Dietitian and Founder of FullWell

“Prior to conceiving, women and men should do blood work to test for vitamin D and iron stores, and do a full thyroid panel and comprehensive metabolic profile. Men should also do semen analysis.”

“Protein needs consistently rise as the pregnancy goes on. During breastfeeding, it's as high as it probably will ever be. Protect your stores of key nutrients to make sure the baby is not taking it from skeletal mass or minerals from your teeth during pregnancy and breastfeeding.”

“Hydrolyzed collagen peptides have a nice balance of amino acids, are easy to digest, and signal to your joints and bones to heal and rebuild. During perimenopause, collagen helps lower core body temperature to support deeper sleep.”

Ayla Barmmer, MS, RD, LDN

Registered Dietitian and Founder of FullWell

“In the initial weeks and months after giving birth, your nutrients needs increase while recovering from pregnancy and for breastfeeding. The placenta leaves a dinner-sized plate hole in your uterus. That wound needs to be filled.”

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.
