Dr. Stasha Gominak
Neurologist and sleep coach
Sleep • vitamin D • and the gut microbiome
About the expert
Focus: Vitamin D, B vitamins, and restorative sleep
Stasha Gominak is a neurologist who became focused on sleep. She argues that vitamin D and B-vitamin deficiencies, linked to the gut microbiome, underlie many sleep problems, and runs a 'RightSleep' program built on that idea.
Why this matters
The presenter, a neurologist, explains poor sleep through a specific proposed pathway. She argues that low vitamin D disrupts the brain chemistry of deep sleep, partly by starving gut bacteria that make the B vitamins sleep depends on. She places far more weight than mainstream medicine on nutrient levels as the root of chronic sleep problems, and builds a step-by-step supplement protocol around that idea.
