Your kidneys are remarkable organs situated on either side of your spine, below the ribs. They play vital roles in maintaining your overall health by filtering about 180 liters of blood daily, removing waste and excess water, flushing out toxins, balancing electrolytes, producing hormones, and supporting various bodily functions. Usually, a balanced diet and proper hydration are sufficient to keep your kidneys healthy, as long as there are no underlying diseases.
Water is essential for the proper functioning of all organs, including the kidneys. They need water to produce urine, which is the body’s primary way of eliminating waste toxins. Insufficient water intake can reduce urine output, potentially leading to kidney issues. Therefore, it’s crucial to drink enough water to enable your kidneys to effectively flush out waste materials.
If the kidneys fail to eliminate toxins and waste, these substances can accumulate in the body, disrupting the normal functioning of not only the kidneys but also the liver and other vital organs. This buildup can result in symptoms such as fatigue, abdominal pain, headaches, water retention, and other health problems. Additionally, the accumulation of waste may contribute to the formation of kidney stones, a prevalent issue among adults and children alike.
What is a Kidney Cleanse?
Your kidneys act as the body’s natural filters, and they’re pretty good at cleaning themselves if you drink enough fluids.
A kidney cleanse involves consuming certain foods and herbs believed to help clear out toxins and improve kidney health. This cleansing diet mainly consists of water, smoothies, juices, herbal teas, and foods that support kidney function and overall health.
Is a Kidney Cleanse Right for You?
The FDA doesn’t make companies prove that kidney cleansing products are safe and effective, so it’s crucial to be cautious about what you consume based on product labels.
If you’re interested in naturally improving your kidney health, it’s best to discuss it with your healthcare provider or a qualified integrative healthcare professional.
Make sure to talk with your provider, especially if you’re pregnant, have underlying kidney issues, or are considering a kidney detox for children.
Herbal Kidney Cleanse
These herbal cleanses usually come in the form of teas taken a few times daily. Some herbs claimed to support kidney health include:
– Resveratrol: Found in grapes and berries, known for its anti-inflammatory properties.
– Ginger: Thought to reduce kidney toxicity.
– Ginseng: May help with chemotherapy-related toxicity.
– Black nightshade plants: Contain flavonoids and alkaloids.
– Turmeric: Believed to reduce urea, prevent kidney inflammation, and aid in waste expulsion.
Other herbs like dandelion tea, red clover, goldenrod, juniper, marshmallow root, burdock root, and nettles are also claimed to have kidney cleansing properties by acting as diuretics, helping to flush out the kidneys and remove excess waste.
It’s important to consult your healthcare provider before using herbs for kidney cleansing, especially if you have kidney stones or other urinary tract issues. A dietitian can also provide insight into how these herbs might impact your health.
Foods to Cleanse Your Kidneys
When it comes to food-based kidney cleanses, the specifics vary, including what you eat and for how long. Generally, these cleanses involve following a restricted diet of specific foods for a few days. This could mean consuming juices, smoothies, or a set list of foods. Remember, it’s crucial to check with your healthcare provider or a dietitian to ensure any cleanse plan is safe for you.
Some kidney cleanses focus on:
– Beet juice: Thought to boost blood flow to the kidneys, although a small 2021 study didn’t find significant benefits.
– Watermelon and lemon juice: Fruits containing citric acid are believed to help prevent kidney stones by binding to calcium and inhibiting the growth of calcium crystals.
– Cranberry juice: Limited evidence suggests cranberries may aid in preventing urinary tract infections.
– Pumpkin seeds: Believed to prevent the buildup of uric acid, one of the compounds contributing to kidney stone formation.

Vitamins for Kidney Health
During a kidney cleanse, some advocates suggest including certain vitamins and minerals. Often, this involves dietary changes along with taking supplements such as:
– Vitamin B2
– Vitamin B6
– Magnesium
A study involving 1,312 adults with type 2 diabetes, who are at higher risk for kidney complications, investigated the effects of Vitamin D and omega-3 fatty acid supplements on kidney function. However, neither was found to be effective in protecting kidney function.
Interestingly, while consuming calcium-rich foods like milk and yogurt may reduce the risk of kidney stone formation, taking calcium supplements could actually increase this risk, according to the National Kidney Foundation.
Taking Care of Your Kidneys
There are proven ways to improve kidney health that you might want to consider before attempting a kidney cleanse:
– Quit smoking and limit alcohol and caffeine intake.
– Keep your blood pressure and blood sugar levels in check.
– Manage your cholesterol levels.
– Stay hydrated by drinking enough water and fluids.
– Maintain a healthy weight.
While there’s no solid evidence that kidney cleanses prevent kidney stones, you can lower your risk by staying well-hydrated and reducing sodium intake. If you’ve had kidney stones in the past, you might want to steer clear of foods high in oxalic acid (oxalates), like chocolate, sweet potatoes, spinach, almonds, and cashews.
For those with chronic kidney disease (CKD), a healthy diet is crucial. Some experts recommend a whole food, plant-based diet rich in fiber, vitamins, and minerals. They’ve also found evidence suggesting that plant-based proteins from sources like peas, beans, and nuts may be gentler on the kidneys compared to animal proteins.
Summary
The aim of a kidney cleanse is to detoxify the kidneys, promoting their health and preventing kidney stones. This often involves using herbs, vitamins, and healthy foods.
However, there’s limited evidence that kidney cleanses actually improve kidney health. While they’re generally safe, they may not provide significant benefits either. Instead, focusing on general health measures like staying hydrated, eating a balanced diet, and managing blood pressure is the best way to support kidney function.
Frequently Asked Questions
Can a kidney cleanse harm your kidneys?
In rare cases, a cleanse high in oxalates could potentially cause kidney damage. Certain vegetables like leafy greens and legumes, which are otherwise healthy, can lead to a condition called oxalate nephropathy if consumed excessively, especially if you have underlying health issues. This condition can be treated, but in severe cases, it may result in end-stage renal disease.
How do I naturally get rid of kidney stones?
For small stones, you may be able to pass them naturally by drinking
plenty of water and taking pain relievers like acetaminophen. Some
natural remedies like apple cider vinegar (containing acetic acid) and
lemon juice concentrate (containing citrate) have been shown to help
prevent kidney stones, but they may not be effective for stones that
have already formed.
