Summary

This study looks at whether drinking cranberry juice for 12 weeks can help overweight or obese adults improve blood sugar, insulin levels, cholesterol, and gut health. About 73 participants will be randomly assigned to receive either a cranberry drink or a placebo, then switch after a break. The goal is to see if cranberries' natural compounds can support metabolic health, but this is not a cure—it's about managing risk factors.
