Abdominal fat and vitamin D both influence how the body regulates inflammation. A new study therefore asked whether vitamin D deficiency adds to the mortality risk associated with obesity. The study followed 5,520 English adults aged 50 or older for six years after measuring their waist circumference and vitamin D levels in their blood. Abdominal obesity was defined as a waist circumference above 102 cm (40 in) in men or 88 cm (35 in) in women. Vitamin D was classified as sufficient above 50 nmol/L, insufficient above 30 through 50, and deficient at 30 or below. Each group was compared with ad... inflammation mortality obesity vitamin d

Listen nowVitamin D, best known for maintaining calcium balance and bone health, is critical in many physiological processes, including blood pressure regulation, immune function, and cell growth. Evidence now suggests vitamin D also influences body composition and muscle strength. A recent study in mice showed that high vitamin D intake increased muscle strength and mass without altering body weight. Researchers fed mice one of three diets, providing low, normal, and high doses of vitamin D for four weeks to achieve deficient, insufficient, and sufficient vitamin D concentrations, respectively. At the... vitamin d obesity aging metabolism hormones muscle
Read moreOmega-3 fatty acids, folic acid, and CoQ10 reduce the risk of cardiovascular disease. Some nutritional components benefit cardiovascular health, but others have no effect on cardiovascular health or may even harm it, according to a recent study. Nutritional components providing the greatest benefit include omega-3 fatty acids, folic acid, and coenzyme Q10 (CoQ10), a vitamin-like compound produced in the body. Researchers analyzed the findings of more than 880 trials involving more than 880,000 participants that investigated the benefits of various macronutrients, micronutrients, and bioactive... vitamin d vitamin c omega-3 melatonin magnesium curcumin selenium folate zinc polyphenol carotenoids cardiovascular supplements Ubiquinol
Read moreThe loss of muscle mass and strength, known as sarcopenia, is a significant problem in aging, affecting both healthspan and quality of life. Findings from a recent study suggest that vitamin D affects muscle function through diverse metabolic pathways. 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. While these other metabolites, part of ... vitamin d muscle
Read moreA 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. Vitamin D is a fat-soluble vitamin that plays essential roles in numerous physiological processes including the regulation of blood pressure, calcium homeostasis, and immune function. Previous work on other coronaviruses demonstrates that vitamin D can counteract a cytokine storm by strengthening the innate immune response and inhibiting ... vitamin d covid-19
Read moreVitamin D is a fat-soluble vitamin that plays critical roles in several physiological processes, including blood pressure regulation, calcium homeostasis, and immune function. Approximately 70 percent of people living in the United States have low vitamin D levels. Findings of a study presented at a 2016 scientific conference suggested that vitamin D insufficiency is associated with increased risk for developing acute respiratory distress syndrome (ARDS). ARDS is a severe form of acute lung injury characterized by rapid breathing, shortness of breath, and a low blood oxygen level and can lead... vitamin d covid-19

It does this by inducing osteoblasts, or premature bone cells, to differentiate into mature, mineralizing specialty cells." [...] > The mice who received an ovariectomy -- and no vitamin C -- had a much lower bone mineral density (BMD) versus controls, whereas mice who received a ovariectomy and large doses of vitamin C, had roughly the same BMD as the controls, suggesting vitamin C prevented BMD loss in this group. ... aging vitamin c bone
