In fact, the study showed an increased risk of post-surgical kidney damage in patients taking curcumin.
A large meta-analysis of 81 randomised trials found no effect of vitamin D supplementation on bone mineral density, fractures, or falls in adults. The study suggests that clinical guidelines should be changed to reflect the best available evidence and that there is little justification for using vitamin D supplements for musculoskeleta...
A recent study analyzing 21 randomized clinical trials with 2,200 participants found that thyroid hormone therapy was not associated with improved quality of life or thyroid-related symptoms in adults with subclinical hypothyroidism. The results suggest that routine use of thyroid hormone therapy may not be necessary for this condition.
A new study published in JAMA Network Open found that perfluoroalkyl and polyfluoroalkyl substances (PFASs) are associated with increases in weight, but exercise and diet may reduce the obesogenic effects of these environmental contaminants. Lifestyle changes can fight the obesogenic action of PFAS.
