In this engaging discussion, Vida Delrahim and Ronit Menashe, co-founders of WeNatal, shed light on the critical 'trimester zero'—the 100 days before conception—where both nutrition and lifestyle can profoundly influence fertility. Ronit emphasizes the importance of mitochondrial health for egg quality, while Vida shares personal experiences linking parental stress to child temperament. They explore how dietary choices and supplements can support pre-pregnancy health, underscoring that both partners play vital roles in successful conception.

Episode notes

ADVICE

Prepare Nutrients 100 Days Before Conception

Build nutrient reserves at least 100 days before conception to support early brain and neural-tube development.
Start choline and folate well in advance because key developmental events occur before a positive pregnancy test.

INSIGHT

Both Parents Shape The Child Before Conception

Both partners shape the embryo through sperm quality and epigenetic signals before conception.
Diet and lifestyle can turn genes on or off, affecting temperament and lifelong health of children.

ADVICE

Optimize Sperm In The 3 Months Prior

Improve male fertility during the three months before conception because sperm regenerate rapidly.
Focus on count, shape, motility and DNA integrity in the pre-conception window.

I used to assume conception began at the first sign of pregnancy — until I learned about Trimester Zero. The 100-day window before conception may be the most powerful period in shaping your baby’s lifelong health — and your own.

In this minisode, I sit down with Vida Delrahim and Ronit Menashe, co-founders of WeNatal, to unpack what science now calls the pre-pregnancy trimester. We talk about how both women and men can dramatically influence fertility and genetics before conception through nutrition, lifestyle, and the health of one mighty organelle — the mitochondria.

About the guests:
After experiencing miscarriages just a week apart, best friends Vida and Ronit were devastated — and confused. Both were healthy, both on prenatal vitamins, and yet doctors dismissed their losses as “random” or “age-related.” They partnered with leading experts, pored over research, and created a science-backed prenatal system for both women and men. What began as a personal mission has grown into WeNatal — a movement giving couples the knowledge, tools, and products to support conception, pregnancy, and the lifelong health of future generations.
