The Three S Model: Stimulus, Supply and Support for Cognitive Health and Dementia Risk | Dr Tommy Wood

Watch the FULL podcast here: https://youtu.be/QeNdkCVYquUCan nutrition and supplements meaningfully lower dementia risk or mainly boost day-to-day focus? They matter within a broader Three S model that links stimulus, supply, and support for brain adaptation. This clip explores why cognitive challenge is the primary stimulus, how supply depends on blood flow, oxygen, and fuel, and how support includes sleep and less chronic stress. We discuss omega-3s, B vitamins, choline, vitamin D, magnesium, zinc, iron, and hydration, the heart-brain connection, and vascular dementia overlap, plus associations showing compounded risk from low D, poor omega-3 and B status, anemia, and homocysteine.
