Gut, estrobolome and neurotransmitters

Millions of women in their 30s–50s are being told they’re “depressed” when their brains and hormones are simply changing.

In this episode, I sit down with Dr. Suzanne Gilberg-Lenz to unpack the truth about midlife mood shifts, rage, and the hormonal fluctuations that mimic depression but aren’t the same. We break down the science of perimenopause, why women are so often misdiagnosed, and how decades of excluding women from research left major gaps in understanding how estrogen, progesterone, and testosterone shape the brain. Dr. Gilberg-Lenz reveals how hormonal changes—starting up to ten years before menopause—can transform mood, cognition, and stress, and how modern science is finally catching up to just how powerfully hormones influence the mind.
