Curcumin administration improves metabolic health in obese/diabetic models by modulating gut microbiota to reduce inflammation and improve intestinal barrier function.

If you consider curcumin, understand that its benefit may come more from its interaction with your gut bacteria than direct absorption. It may help with insulin sensitivity and gut barrier integrity, especially if you have metabolic issues. Formulations that enhance bioavailability (like with piperine or lipids) may be more effective.
