Vitamin D is far more than just a vitamin—it’s a potent steroid hormone regulating nearly 5% of our genome. Yet, remarkably, up to 70% of Americans aren’t getting enough, placing them at increased risk for dementia and Alzheimer’s disease. In this video, I explore compelling new evidence from a study involving over 12,000 participants, demonstrating that vitamin D supplementation can reduce dementia risk by an impressive 40%, protecting even adults with genetic Alzheimer’s risk (ApoE4 carriers).
