Researchers from the Australian University analyzed health data from more than 290,000 people at the UK Biobank, comparing vitamin D levels with brain imaging to measure the size of gray matter, white matter and the hippocampus, the part of the brain responsible for operating. like memory.

The scientists found that participants with genetically higher levels of vitamin D had a reduced risk of dementia, with dementia rates decreasing with higher vitamin D levels, up to 50 nmol/L, then the benefit was less pronounced.

She added: “In some contexts, where vitamin D deficiency is relatively common, our findings have important implications for dementia risk. Indeed, in this UK population , we observed that up to 17% of dementia cases could be avoided by increasing vitamin D. levels within the normal range.”


Both low levels of vitamin D and dementia are not uncommon in the United States. It is estimated that 40% of Americans do not get enough of this vitamin. And about 5.8 million Americans have Alzheimer’s and dementia-related conditions, a number that is expected to grow as the population ages.

“Most of us are probably fine, but for anyone who for any reason may not be getting enough vitamin D from the sun, dietary changes may not be enough and can be fatal. may need additional.”

You’re better off going to your doctor to have your vitamin D levels checked every year. If your levels are low, they may recommend a food supplement. According to the National Institutes of Health, adults are advised to get at least 600 IU of vitamin D per day, between foods and supplements (although that number is controversial and some doctors believe it should be high). than).
