Can Cranberry Juice Flush Out Kidney Stones?

There are various natural remedies that help in dissolving and flushing out kidney stones from the body. What about cranberry juice? Does it work? Learn the answer here.

Majority of the kidney stones are formed due to deposition of chemicals in the kidneys that are not passed in the urine. Crystals of these chemicals form and get attached to kidney walls particularly in highly concentrated and acidic urine. Kidney stones are formed of several different types of chemicals including uric acid, struvite and calcium oxalate crystals. Kidney stones may be dissolved and passed in urine by various natural products; however, you should consult your physician before consuming any new product.

Does Cranberry Juice Help Kidney Stones?

Cranberry is the bog plant native to the region of North America. Its fruit is rich in antioxidants and vitamin C. Citrate and magnesium are two compounds that inhibit the formation of renal stones. Both of these are present in urine. To effectively prevent kidney stones, a natural beverage should increase the levels of inhibitors and simultaneously decrease the levels of compounds which form stones.

Consuming cranberry juice raises the amount of citrate, magnesium, calcium and oxalate in urine. This implies that while increasing two inhibitory compounds, it also raises the amount of two compounds that form calcium oxalate stones.

Hence, consumption of cranberry products actually raises the risk of renal stones, which form from oxalate and calcium. Additionally, cranberry juice may also decrease urine acidity, which raises the risk of formation of uric acid renal stones.

However, cranberry juice prevents infection of the urinary tract; hence, it prevents formation of struvite kidney stones. This kind of stone is formed of ammonium, phosphate and magnesium and it is formed only when there is an infection of the urinary tract is present. Does cranberry juice help kidney stones? This implies that though the struvite stone components may be increased by consuming cranberry juice, their formation is actually prevented as it prevents UTIs. This occurs as it prevents the sticking of bacteria to the bladder wall.

A substance referred to as polyphenolic material is present in cranberry juice that helps in reducing viruses and bacteria. It also contains antioxidants which protect from processes of aging. It has high amounts of acidity, which is responsible for its effectiveness in blocking bacteria from attaching to renal cell walls. Its high vitamin C content boosts your immunity. However, before consuming cranberry juice, it is vital to determine the type of kidney stone you have so that you know whether you can take it safely or not. Hence, to begin with you should consult your physician.

How to Prepare?

Does cranberry juice help kidney stones? Sometimes it works. How to include it to your diet? You may eat the whole berries or you can take juices or extracts of cranberry (100% natural) regularly to prevent kidney stones, urinary infections and to remove existing kidney stones. The recommended dose is around one to two cups of cranberry juice (unsweetened) per day. Cranberry is also available in capsule form in the market; however, 1 capsule has only half cup of cranberry juice, so 2-4 capsules per day should be taken.

A word of caution: As cranberry juice contains oxalate, consuming it regularly can result in calcium oxalate stones of the kidneys while preventing formation of calcium phosphate and struvite stones. Hence, you should take a break in between and not consume it regularly.
