Episode Details

Vitamin D may be more than a supplement issue—it could be a clue to why sleep, mood, and recovery break down. In this condensed recap of The Diary of a CEO, Steven Bartlett and neurologist Stasha Gominak unpack why she believes vitamin D functions like a hormone, how sunlight, gut health, and brain chemistry shape sleep, and why common fixes for insomnia may miss the root cause. In the full episode, this recap trims the conversation into a few minutes of the most important takeaways, including her view on REM sleep, the autonomic nervous system, vitamin D deficiency, B vitamins, and personalized treatment protocols. You’ll also hear the patient stories behind her approach and learn why she says supplementation alone isn’t the same as getting real sunlight. Listen now to get the key ideas in minutes.
