In this episode of The Perfect Stool, host Lindsey Parsons interviews neurologist and sleep coach Dr. Stasia Gominak about the interconnected roles of vitamin D, the B‑vitamin complex, and the gut microbiome in sleep regulation, pain, autoimmune disease, and overall health. Dr. Gominak describes how low vitamin D was first linked to poor sleep in her neurology patients, leading her to supplement D and observe improvements that later faded, accompanied by neuropathic pain and IBS‑like symptoms. She hypothesizes that vitamin D acts as a trophic factor for beneficial gut bacteria, but prolonged supplementation can deplete bacterial‑derived B vitamins, creating secondary deficiencies. Historical research is reviewed showing that B vitamins were originally identified as bacterial growth factors and that four core gut phyla exchange these vitamins. Clinical anecdotes illustrate how high‑dose pantothenic acid (B5) and B‑complex (B100) can cause adverse effects, prompting a personalized dosing strategy (B50 for milder cases, B100 for severe, multi‑system illness). The conversation also covers optimal serum vitamin D levels (60‑80 ng/mL for sleep), the balance between sun exposure and oral supplementation, the impact of vitamin D on skin cancer risk, and the broader implications for immune function, COVID‑19 outcomes, and autoimmune disease. Dr. Gominak emphasizes that restoring a healthy microbiome—through adequate vitamin D, appropriate B‑vitamin repletion, and prebiotic support—underlies the therapeutic benefits, while probiotics alone are insufficient. She promotes her "Right Sleep Program" workbook for patients to track symptoms, supplement regimens, and lifestyle factors.
