However, it’s important to remember that while there is not yet enough evidence to make health claims on supplements and products, there have been trials conducted on the use of curcumin for inflammatory disorders such as osteoarthritis which have been shown to have benefit. For example, a 2016 systematic review and meta-analysis (a gold standard of nutrition research) by Daily et al. concluded that curcumin supplementation effe
