Vitamin D is crucial for gut health

Lower levels of vitamin D found in inflammatory bowel disease (IBD) patients are linked to inflammation, potentially playing a role in the disease’s development, findings from a cross-sectional observational study published in Medicine show.  The journal is published in the Lippincott portfolio by Wolters Kluwer.

The study investigated the link between vitamin D levels and inflammatory bowel diseases, focusing on Crohn’s disease (CD) and ulcerative colitis (UC). In a group of 106 participants, including 92 IBD patients and 14 healthy controls, the research found a substantial association between lower serum vitamin D levels and increased… Continue reading

Low Vitamin D and High Blood Pressure

Low levels of vitamin D may be a cause of high blood pressure, according to a new study published on June 25, 2014 in The Lancet Diabetes & Endocrinology.

Vitamin D is nicknamed the sunshine vitamin because the body produces vitamin D when exposed to sunlight. People also get vitamin D through foods such as eggs, milk, yogurt, tuna, salmon, cereal and orange juice.

In the new study, researchers analyzed genetic data from more than 146,500 people of European descent in Europe and North America. For each 10 percent increase in vitamin D levels, there was an 8 percent decrease… Continue reading

Vitamin D and Fatty Liver

Non-alcoholic fatty liver disease (NAFLD) has become the most common form of chronic liver disease in Western countries with a prevalence as high as 30%, already exceeding viral hepatitis and alcoholic fatty liver disease. Emerging evidence suggests that vitamin D may play a role in the pathogenesis of NAFLD.

Vitamin D is a fat-soluble vitamin formed in the skin from 7-dehydrocholesterol during exposure to solar ultraviolet B (UVB) radiation. Although vitamin D can be derived from the diet, few foods naturally contain vitamin D, such as oily fish. Vitamin D from the skin or from diet is metabolised in the… Continue reading

Vitamin D: Forms, Mechanisms and Lab Testing

Vitamin D has become one of the most widely discussed and intensely scrutinized supplements in recent history. The renewed interest is due in large part to the startling prevalence of vitamin D deficiency worldwide and the proliferation of articles linking deficiency to multiple clinical conditions other than bone health.

Learn more about the critical role of Vitamin D, consequences of its deficiency and how you can have it tested.

Vitamin D and Infections in School Children

Inadequate vitamin D status is highly prevalent in children worldwide, even in equatorial regions with lots of sunshine. Recent epidemiologic studies indicate that low plasma vitamin D concentrations are related to increased incidence of respiratory infections, including acute lower respiratory tract infections and respiratory syncytial virus (RSV) disease in infants and children less than 5 years of age. Furthermore, vitamin D supplementation in randomized controlled trials conducted among schoolchildren resulted in reduced incidence of influenza A infection and acute respiratory infection.

Among school-age children, respiratory and gastrointestinal infections account for increased school absences and parental absenteeism from work, as well as a sizeable proportion of physician visits.

Vitamin D Curbs Albuminuria in Kidney Disease

Vitamin D supplementation decreases albuminuria and might slow the progression of chronic kidney disease (CKD), according to Spanish researchers.

“The study suggests that vitamin D repletion with daily mild doses of cholecalciferol may be effective to reduce albuminuria in patients with CKD 3-4 stage, with potential long-term benefits for this population,” Dr. Pablo Molina told Reuters Health by email. “In addition, we observed a modest but significant decline in PTH (parathyroid hormone) levels after cholecalciferol administration.”

In a report online August 24 in Nephrology Dialysis Transplantation, Dr. Molina of Hospital Universitario Dr Peset, Valencia, and colleagues note that several observational… Continue reading
