Mosley argues vitamin D could guard brain health and dementia risk
On Just One Thing, Michael Mosley promotes vitamin D as a potential shield for the brain and a guard against dementia, noting UK winters limit sun-driven production. He cites studies linking low vitamin D to higher dementia risk and mentions that vitamin D receptors exist in most cells, which could affect brain health; NHS guidance recommends most people take 10 micrograms daily in autumn/winter and warns against exceeding 100 micrograms daily.
