“Clinicians determine a person's vitamin D status by measuring 25-hydroxyvitamin D3, or 25(OH)D3 — the inactive circulating form of vitamin D. However, a new technique, high-throughput liquid chromatography-tandem mass spectrometry (LC-MS/MS), allows researchers to quantify additional vitamin D metabolites.”

“Conversely, people whose magnesium levels are sufficiently high require less vitamin D supplementation to achieve healthy levels. The recommended dietary allowance for magnesium for adults between the ages of 31 and 50 years is 420 milligrams for men and 320 milligrams for women per day.”

“A cytokine storm is an excessive release of pro-inflammatory molecules that occurs during severe COVID-19 and is a common cause of death. A new study suggests that vitamin D could reduce the risk of developing a cytokine storm and decrease COVID-19 mortality.”

“Supplemental vitamin D intake, body mass index, and race/ethnicity had the greatest influence on vitamin D concentrations, and genetic variants had only a minor influence. Black women had the lowest vitamin D concentrations among the cohort, possibly contributing to their poorer outcomes following breast cancer diagnosis.”

“They found that vitamin D inhibited hyperglycemia-induced NLRP3 activation and IL-1 beta production, leading to lower levels of inflammation. Further investigation revealed that vitamin D upregulated AMPK production in the cells, which likely contributed to the reduction of inflammation.”

“Young children who received supplemental vitamin D were less likely to have neurobehavioral problems later in childhood than those who didn't. Researchers gave 346 infants either low-dose (400 IU) or high-dose (1,200 IU) vitamin D daily from two weeks to two years of age.”

“A recent study found that higher vitamin D levels may reduce the risk of developing dementia in older adults with prediabetes. Researchers drew on data collected from a large cohort of more than 34,000 older adults enrolled in the UK Biobank, all of whom had prediabetes but did not have dementia at the start of the study.”

“Researchers measured concentrations of vitamin D in four regions of the participants' brains and reviewed the participants' cognitive assessments. They found that higher brain concentrations of vitamin D were associated with 25 to 33 percent lower odds of having dementia or mild cognitive impairment at the last assessment before death.”
