What is Cucumber Juice?

Cucumber juice is a refreshing beverage prepared by blending or juicing fresh cucumbers and straining the pulp if desired. It can be consumed plain or combined with ingredients such as lemon, mint, ginger, celery, apple, or spinach for added flavor and nutritional value.

Since cucumbers contain about 95–96% water, the juice is naturally hydrating while remaining very low in calories. It also contains antioxidants like flavonoids, cucurbitacins, and lignans that may help protect cells from oxidative stress.
