Biohacking with Brittany by Brittany Ford

May 28, 2026 The Complete Maternal Mental Health Protocol: Peptides, Anxiety, Depression, Bioregulators and the Science of the Postpartum Brain | Her Stack Series

In this Her Stack series episode, I open up about maternal mental health, postpartum anxiety, and the invisible biological load mothers carry long after the six-week checkup is over. This episode is not just for the newly postpartum mother. It is for the mother whose kids are four, eight, fifteen, and still asking herself why she does not feel like herself.

I share why motherhood structurally changes the brain, hormones, and nervous system, and why so many mothers are left feeling anxious, foggy, depleted, or unlike themselves without ever being properly screened or supported. I walk you through the science of the postpartum neurosteroid withdrawal, the gray matter changes that persist for years, and the five-system map underneath maternal brain fog.

Then I break down the full four-pillar protocol I use with my one-to-one clients: foundational nutrition, lifestyle and biohacking tools, the supplement layer including some of the most under-discussed compounds for the maternal brain, and the advanced peptide layer including Semax, Selank, NAD+, and bioregulators.

This is the episode every mother needs. Send it to one.

42:15 — Magnesium L-threonate, glycine, vitamin D, and low-dose methylene blue for sleep, brain fog, mitochondrial support, and nervous system balance

45:25 — Why peptides are an advanced layer and should come after nutrition, lifestyle, and supplement foundations

46:10 — Semax and Selank for anxiety, cortisol support, BDNF, dopamine, brain fog, memory, and maternal brain support

58:15 — Why postpartum anxiety and depression need different kinds of support, and why SSRIs work for some mothers and not others

1:00:00 — Why lingering symptoms matter and which labs mothers should check
