I Drank Cranberry Juice Every Day for a Week — Here’s What Happened to My Body

Before I began, I did some research. Cranberry juice isn’t just a flavorful drink — it’s been studied for its role in preventing urinary tract infections (UTIs), thanks to natural compounds called proanthocyanidins that help prevent harmful bacteria from sticking to the urinary tract walls. For older adults, especially women, this is an especially important benefit.

But that’s just the beginning. Cranberries are rich in vitamin C, antioxidants, and anti-inflammatory properties that may also support heart health, improve immune function, and even help with digestive comfort.

However, not all cranberry juice is created equal. Many brands add sugar — sometimes more than a can of soda — which can cancel out many of the health perks. That’s why I chose 100% pure, unsweetened cranberry juice, even though I knew it would be a bit of a shock to the taste buds.

Day One: A Tart Wake-Up Call

I decided to drink one 8-ounce glass of pure cranberry juice each morning with breakfast. No sweeteners, no ice — just straight juice. I won’t lie: it was tart. Very tart. But I got used to it more quickly than I expected.

Throughout the day, I drank plenty of water to stay hydrated and help balance the acidity. I kept my meals light and nutritious, aiming to give this experiment the best shot at success.
