When it comes to raising a patient’s overall vitamin D status, supplementation with vitamin D3 may be more effective than vitamin D2, researchers found.
8/14/13 Action Points A diet rich in fatty fish appeared to protect against rheumatoid arthritis in women. Point out that fish oil supplementation is the only source of long-chain n-3 polyunsaturated fatty acids n-3 (PUFAs) consistently associated with a reduced risk of RA, and studies of dietary sources of n-3 PUFAs have yielded inconsistent results. […]
08.12.2013 Action Points Note that this randomized trial failed to demonstrate that vitamin D supplementation improves blood pressure in older adults. Be aware that prior observational findings demonstrating an inverse relationship between vitamin D levels and systolic blood pressure are unlikely to represent a causal link in the light of this new evidence. Supplementation with […]
Tuesday, 30 July 2013 21:10 By Erik Goldman Researchers in Spain have shown a definitive link between low serum vitamin D and the prevalence of obesity. Rather than being a consequence, the vitamin deficiency may play a causative role.This prospective trial begun in 1996 involved 1,226 individuals who were evaluated 6 and 9 years after […]
7/17/13 by Todd Neale Senior Staff Writer, MedPage Today Action Points This cohort study demonstrated an association between low vitamin D levels at baseline and functional decline over time in a population of older individuals. As functional disability may limit access to sun exposure, the direction of causality in this relationship is unclear. For individuals […]
7/3/13 by Nancy Walsh Staff Writer, MedPage Today Action Points SLE patients with low levels of 25-hydroxyvitamin D were given weekly supplements of 50,000 units of vitamin D2 plus 200 units of calcium/vitamin D3 twice daily. A 20-ng/ml increase in the 25(OH)D level was associated with a significant but modest decrease in the odds of […]
