Kidney stones form when minerals and waste products in the urine crystallize and harden, creating small—sometimes very painful—solid masses. While medical treatments such as ureteroscopic removal or alpha-blocker medications are often used, many people are encouraged to increase their fluid intake with drinks that may help dilute urine, soften stones, and support the body’s natural ability to flush them out.

Below are five beverages commonly believed to assist the body in breaking down kidney stones into smaller, easier-to-pass fragments.

1. Water

According to an analysis from the National Kidney Foundation, people who produce 2–2.5 liters of urine per day have up to a 50% lower risk of developing kidney stones.

For those who already have stones, drinking plenty of water is essential. Adequate hydration helps dilute urine, reduce crystal formation, and promote the movement of small stones out of the urinary tract. Consistent water intake throughout the day is especially important for preventing stones from getting larger.

2. Lemon Water

Lemons are rich in citrate, a natural compound known to help prevent calcium-based stones—the most common type, making up roughly 80–85% of all kidney stones, according to Harvard Health Publishing.

Regularly drinking lemon water may help increase urinary citrate levels, which can slow down stone growth and assist in breaking down existing stones more quickly. Adding fresh lemon juice to daily water intake is a simple, natural way to support kidney health.

3. Celery Juice

Some studies have found that people with kidney stones tend to consume less celery than those without stones. Celery contains plant compounds that may support healthy urine flow and reduce the buildup of minerals that lead to stone formation.

A 2019 study on mice also suggested that celery extract may help break down kidney stones. Blending fresh celery with water to make a daily juice can be a gentle way to support hydration and the natural elimination of stones.

4. Apple Cider Vinegar Drink

Apple cider vinegar is a popular home remedy for kidney stones. It contains acetic acid, which is believed to help soften and dissolve stones, making them small enough to pass more comfortably through the urinary tract.

Additionally, apple cider vinegar provides a small amount of potassium, a mineral that may help support overall urinary balance and reduce the likelihood of new stone formation. Diluting 1–2 tablespoons in water is a common way people consume it.

5. Wheatgrass Juice

Wheatgrass has long been used to enhance general wellness and support detoxification. It may increase urine flow, helping the body flush stones more easily.

A 2017 study reported that wheatgrass extract could inhibit crystal formation in urine by up to 88%, suggesting that it may help prevent stones from growing or forming. Drinking wheatgrass juice regularly can be a natural addition to a kidney-supporting routine.
