[00:00:00]Vitamin D is phenomenal. We have vitamin D receptors all over our brain and they're abundantly found in the hippocampus and the memory [music] centers of our brain. There was actually a study done on centenarians in China, but it was done in women and they showed that the women who preserved their cognitive functions and who didn't get Alzheimer's disease had high levels of vitamin D. So they weren't vitamin D deficient. In fact, being vitamin D deficient can increase your risk of all cause dementia by 40%. Likely having a high level of vitamin D, which is around 60 nanograms per deciliter, can lower your risk of getting Alzheimer's disease by around 80%.
