Although vitamin D is best known for its role in bone health, this fat-soluble vitamin participates in many physiological processes, such as blood pressure regulation, immune function, and cell growth. Now, new research shows that vitamin D also supports neurodevelopment. 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. Then, when the children were between six and eight ye... vitamin d brain behavior mental health development
Read moreVitamin K2 – a form of vitamin K produced in the gut – plays important roles in blood clotting, bone mass maintenance, and blood vessel contractility. But new research shows that supplemental vitamin K2 also improves diabetes markers. People with type 2 diabetes who took supplemental vitamin K2 had better markers of glycemic control than those who took a placebo. Researchers performed a three-part study in humans and mice. First, they conducted a randomized controlled trial involving 60 adults who had type 2 diabetes. Half of the participants took vitamin K2 every day for six months, while t... metabolism diabetes insulin resistance vitamin k insulin
Read moreTaking vitamin D may prevent Alzheimer's disease, a new study shows. People who took vitamin D were 40 percent less likely to develop Alzheimer's disease than those who did not. The study involved more than 12,000 adults who were dementia-free at the time of enrollment. Participants provided information about their vitamin D intake and underwent regular cognitive evaluations over a period of 10 years. Even after taking other risk factors into account, such as age, sex, education, race, cognitive diagnosis, depression, and whether they carried the APOE4 gene, people who took vitamin D were 40... vitamin d brain alzheimer's aging
Read moreAccording to findings from a recent study, the brains of people with vitamin D deficiency age faster than those with adequate vitamin D levels. This is particularly true for males. Researchers measured blood vitamin D concentrations in the blood of more than 1,800 healthy adults. Then they scanned the participant's brains to assess their brain aging. They calculated the participants' brain age based on chronological age and brain volume. They found that participants with vitamin D deficiency (which the researchers defined as less than 16.08 nanograms (ng) per milliliter (ml) for the purposes ... vitamin d brain aging
Read moreWomen with the highest vitamin K1 intake were nearly half as likely to require long-term hospitalization due to hip fracture compared to women with the lowest intake, a recent study shows. Those with higher vitamin K1 intake were nearly one-third less likely to experience any kind of fracture that required hospitalization. Researchers tracked hip fractures among more than 1,300 older women (70 years and older) living in Australia for about 15 years. They also assessed the women's vitamin K1 intake using food frequency questionnaires and measured their blood vitamin D concentrations. They fou... vitamin d aging vitamin k
Read morePeople with higher brain concentrations of vitamin D were 25 to 33 percent less likely to develop dementia or cognitive impairment, a recent study has found. Those with higher vitamin D concentrations also performed better on tests of cognitive function than those with lower concentrations. The study involved 290 participants enrolled in the Rush Memory and Aging Project who had undergone regular physical and cognitive assessments when they were alive and agreed to donate their brains for study upon their deaths. Researchers measured concentrations of vitamin D in four regions of the participa... vitamin d brain alzheimer's dementia
Read moreBreast cancer is the most common cancer in women worldwide, with nearly 2.6 million new cases diagnosed in 2020. Robust evidence demonstrates that nutritional factors may mediate the risk of many types of cancer (https://www.bmj.com/content/368/bmj.m511.full). Findings presented at the annual conference of the American Society of Clinical Oncology suggest that vitamin D status influences outcomes among breast cancer survivors. Vitamin D is a fat-soluble vitamin stored in the liver and fatty tissues. It plays key roles in several physiological processes. Research suggests that vitamin D exerts... vitamin d breast cancer
Read moreVitamin D regulates over 900 genes in the body that affect the immune, musculoskeletal, and endocrine systems, among others. Previous research has shown that vitamin D deficiency may decrease athletic performance. A study published in early 2020 in soccer players demonstrates the importance of maintaining year-round adequate vitamin D levels for athletes. Estimates suggest that 60 percent of outdoor and 64 percent of indoor athletes may have insufficient vitamin D levels (defined as less than 30 ng/ml), which may impair aerobic capacity and muscle recovery. High-dose supplementation of 5,000 I... vitamin d

From the article: > Patients administered vitamin C had a rapid and statistically and clinically significant improvement in mood state, but no significant change in mood occurred with vitamin D, the researchers discovered.
