A recent study suggests that increasing vitamin D intake may significantly lower the risk of developing dementia in older adults.
Research indicates that one essential vitamin could make all the difference in cognitive decline and brain longevity: vitamin D.According to an observational study published in Alzheimer's & Dementia, older adults who increased their vitamin D intake were 40% less likely to develop dementia.The study also learned quite a bit about how individual factors (e.g., demographics, genetics, behavior) play into the equation.
The dementia study design Researchers evaluated the effects of vitamin D exposure on dementia incidence in 12,388 older adults (average age 71) from the National Alzheimer's Coordinating Center (NACC) data set.All participants were dementia-free at the baseline evaluation and given one of the following cognitive diagnoses: Additionally, participants were split up into a vitamin-D-exposed group (i.e., individuals that took one of three types of vitamin D supplements—D2, D3, or a combination of vitamin D and calcium—before the baseline exam) and a non-exposed group (i.e., individuals that did not increase their vitamin D intake via supplementation throughout the study). Can vitamin D exposure predict cognitive decline outcomes? When looking at demographics, genetics, and myriad other factors, the influence of vitamin D exposure on dementia incidence and survival varied from group to group in interesting ways. Overall, increased vitamin D intake was found to have potential for dementia prevention, particularly before the onset of cognitive decline. The takeaway While other studies have found that vitamin D deficiency increases the risk of dementia by one-third and higher brain concentrations of vitamin D are linked to positive cognitive health outcomes, participants' blood serum vitamin levels were not documented in this stud

Vitamin B12 Deficiency Linked to Autoimmune Thyroid DiseasesA recent study published in Endocrine, Metabolic & Immune Disorders - Drug Targets suggests a connection between vitamin B12 deficiency and autoimmune thyroid diseases (AITD). Researchers found that patients with AITD had significantly lower levels of vitamin B12 compared to those without the condition. Additionally, individuals deficient in B12 demonstrated significantly higher levels of anti-TPO antibodies, which can interfere with thyroid function. The study authors recommend determining vitamin B12 levels in patients with autoimmune thyroiditis as a potential diagnostic tool.
