Nearly 1 in 3 American adults now take vitamin D, but Dr. Stasha Gominak says many of them are taking it wrong, and that done carelessly, supplementing can leave you worse off than before. Dr. Stasha Gominak practiced neurology for over 20 years. She earned her MD from Baylor College of Medicine and completed her neurology residency at the Harvard-affiliated Massachusetts General Hospital. After working with her own patients, she believes that nearly everyone struggling to sleep shares the same hidden deficiency, a conclusion she published in 2 papers and built into RightSleep, the method she now teaches full time. She explains: ◼ Why she believes your skin is the best producer of vitamin D, and why she says no amount of pills or salmon can replace it ◼ Why she believes insomnia isn't a behavior problem but a chemical deficiency, and what she thinks changed when we moved indoors ◼ The role she says your gut bacteria play in producing your B vitamins ◼ Why she believes taking vitamin D on its own can burn through your B vitamins, and what she says happened when she tried it herself ◼ Why she connects the rise in conditions like ADHD, depression, fatty liver and diabetes to the same period, and what she thinks links them ◼ Why she considers supplements a form of biohacking, and just as risky as any drug if you get them wrong The views expressed are those of the guest, and this conversation is intended for general informational purposes only.
