Essentials: How to Optimize Female Hormone Health for Vitality & Longevity | Dr. Sara Gottfried

This Huberman Lab Essentials conversation opens with Andrew Huberman introducing his guest, Dr. Sara Gottfried, and asking whether a woman of any age gains useful information from knowing about her mother's, or even her grandmother's, experience with hormones. He frames it as a question about what conversations women should have, with themselves and with family members, to understand their own needs.

Gottfried describes her work as sitting "at the interface between genetics and environment" and says it is essential to know what your grandmother and especially your mother went through. She would start with trauma and intergenerational trauma, which she believes affects the endocrine system "so hugely, especially cortisol signaling." She then names three female conditions she describes as having a strong genetic component: endometriosis, fibroids and polycystic ovarian syndrome. She adds that most of these run in her own family.

Huberman asks her to go decade by decade, starting at puberty. For teenagers, Gottfried points to cortisol as the most interesting thing to measure. She considers the balance between estrogen and progesterone at that age less helpful because of "a lot of variability due to the immaturity of the system." Her exception is a teenager with very regular periods, for whom early benchmarking may be worthwhile. In general, she finds benchmarking is best done in the 20s or 30s. Asked whether cycles are irregular when menstruation begins, she says that for many women they are, and that oral contraceptives and other forms of contraception mean that "you have no idea what the normal cycle is."

For women in their 20s, she recommends a baseline of estrogen, progesterone and testosterone. She says estrogen often "dominates in that tango," which in her view raises the risk of fibroids and endometriosis. She would also want to look at DHEA and the wider androgen pathway, and at estrogen metabolites, some of which she calls protective while others "are a bit like Homer Simpson" and cause "all kinds of problems in your body." She also wants stool testing to assess the microbiome.

On timing, Huberman notes that testing has to be matched to the menstrual cycle. Pressed to choose a single window, Gottfried picks roughly day 21 to 22 for a woman in her 20s. For most women, with a cycle that averages 28 days, that is about a week before the period starts. She says this is harder to apply to irregular cycles. As women age and progesterone production declines, cycles usually shorten, so she would test earlier, around day 19 or 20.

She compares testing methods. Blood is "the cheapest thing" and usually covered by insurance. She prefers dried urine, though, because it gives her metabolomics as well as hormone levels. She calls blood testing less comprehensive, a "quick little snapshot while the needle's in your vein for 30 seconds," and uses it when she has to.

Later, Huberman sums up the list for a woman in her late teens or early 20s: testosterone, estrogen, thyroid and cortisol, plus attention to the microbiome and to the number and timing of daily bowel movements. He asks whether the same applies at every age. Gottfried agrees but says the opportunities differ by decade. Knowing in your teens that your androgens are high, perhaps hinted at by "a few extra hairs on your chin," could change how you look after yourself over a lifetime. Looking back at herself at 27 on the wards at UCSF, she says that if she had known she was "such a high cortisol person," she would have changed her behavior.
