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.

11:40 — The neurosteroid withdrawal nobody warned you about, and the FDA's $34,000 drug that proves it is real
13:50 — Pillar 1: DHA, protein, ferritin, blood sugar stability, and methylated Bs for the maternal brain
22:40 — Pillar 2: Protected sleep cycles, morning sunlight, vagal nerve activation, and red light to the brain
28:00 — Yoga nidra and NSDR as the workaround for mothers who cannot engineer a protected sleep cycle
32:45 — Simplifying routines, meals, outfits, and planning to reduce mental load

38:40 — Creatine for maternal mental health, depression support, and cognitive fatigue in sleep-deprived moms
40:50 — Saffron and inositol for postpartum mood, anxiety, racing thoughts, and the "can't shut off the brain" symptoms
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
50:00 — NAD+ and bioregulators (Cortagen, Cerluten, Epithalon) for maternal energy, neuronal support, circadian rhythm, melatonin, sleep, and long-term brain health
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
