Apple cider vinegar appears in everything from salad dressings to online “kidney cleanse” routines. If your creatinine is high or you have chronic kidney disease, it is tempting to hope that something already in your kitchen could help. There is no good evidence that drinking apple cider vinegar reverses CKD, restores kidney filtration, or reliably lowers creatinine.

That does not mean vinegar must disappear from every kitchen. A little used as a food ingredient is a different decision from drinking concentrated vinegar every day as a treatment. The amount, your symptoms, medicines, and whether you have a fluid restriction all matter.
This guide looks at the claims, the limits of the evidence, and the questions worth asking before turning apple cider vinegar into a health routine.
What is apple cider vinegar?
Apple cider vinegar is made from fermented apple juice. Like other vinegars, it is acidic. People use it to add flavour to food, preserve certain foods, or make dressings and sauces.
Online kidney claims usually involve drinking it, sometimes mixed with water, honey, lemon, or other ingredients. That changes the question from “Can I use this in food?” to “Should I take this repeatedly for a medical purpose?” Evidence of benefit and possible harms deserve a closer look when the goal is to treat kidney disease.
A product being familiar, natural, or inexpensive does not establish that it can improve kidney function.
Can apple cider vinegar reverse kidney disease?
No evidence establishes apple cider vinegar as a treatment that reverses chronic kidney disease. CKD has many possible causes, and its care depends on the diagnosis, kidney function, urine findings, blood pressure, diabetes status, and other medical factors.
You may see testimonials showing a lower creatinine result after someone started drinking vinegar. A before-and-after result cannot show that vinegar caused the change. Results can vary for several reasons, and the person may also have received medical treatment or had a temporary problem that improved.
If you have CKD, ask your clinician which steps are relevant to the cause of your condition. For a broader discussion, read can kidney disease be reversed?.
Does apple cider vinegar lower creatinine?
There is no reliable basis for recommending apple cider vinegar to lower creatinine in people with CKD. Creatinine is a blood measurement used to help estimate kidney function. An unexpectedly high result needs interpretation, not a home experiment aimed at changing the number.
Your clinician may consider previous results, estimated GFR, urine tests, recent illness, medicines, and other details. If dehydration has affected a result, that calls for advice appropriate to your health—not an assumption that an acidic drink can repair the kidneys.
See what causes high creatinine for the possible explanations, and what may actually help lower creatinine for a cause-focused approach.
Why do people believe it helps?
Apple cider vinegar is often discussed alongside claims about blood sugar, weight, digestion, and “detoxification.” It is easy for a claim about one aspect of health to become a larger promise about the kidneys.
Even if a small study examines one effect of vinegar in a particular group of people, it does not establish that vinegar prevents kidney failure or treats CKD. Kidney outcomes require their own evidence. A laboratory experiment, animal study, or personal story cannot answer whether a person with kidney disease should drink vinegar daily.
The wording of a claim matters. “Can be used to flavour a meal” is easy to assess. “Reverses kidney damage” is a medical claim that requires convincing research in people with kidney disease.
Could it help by controlling blood sugar?
If you have diabetes, managing blood glucose is an important part of kidney care. That fact does not make apple cider vinegar a replacement for diabetes treatment.
Studies of vinegar and blood sugar have examined questions that are different from whether it treats diabetic kidney disease. Do not stop or change diabetes medicines because an article suggests vinegar has an effect. Talk to the clinician managing your diabetes about your blood glucose pattern and treatment plan.
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) describes reaching blood glucose and blood pressure goals as central to slowing or preventing diabetes-related kidney disease. Those are measurable parts of a care plan. An unproven vinegar routine should not distract from them.
Does apple cider vinegar “detox” the kidneys?
The word detox can make a claim sound scientific without explaining what is being measured. A vinegar drink does not perform the filtering work of healthy kidneys, reverse kidney scarring, or replace dialysis.
If you are worried about a high urea or creatinine result, ask why it is high and what follow-up is needed. A clinician may need to check your kidney function, urine, medicines, symptoms, and other results. Drinking a “cleanse” cannot provide that diagnosis.
Our article on kidney cleansing diets and detox claims takes a closer look at this kind of promise.
What about kidney stones?
Kidney stones and chronic kidney disease are different conditions. Advice for one should not automatically be applied to the other.
A study about whether apple cider vinegar affects stone-related measurements would not prove that it repairs kidney damage or improves eGFR. If you have had stones, ask what type of stone you had and what prevention plan your clinician recommends. Avoid treating vinegar as a universal answer to every kidney problem.
If you have both stones and CKD, fluid advice can require particular care. A general instruction to drink large amounts may conflict with a restriction given for another condition.
Is apple cider vinegar safe to drink every day?
Using a small amount of vinegar in food is different from repeatedly drinking it as a health product. Its acidity can irritate the mouth or throat and, with frequent exposure, contribute to tooth enamel erosion. Concentrated or undiluted use raises obvious concerns about irritation.
A person with CKD should also avoid adding a new remedy to a routine without considering their medicines, symptoms, and other conditions. If you have reflux, trouble swallowing, dental problems, or a history of low potassium, mention those concerns to a clinician before drinking it regularly.
Do not assume a supplement capsule or concentrated product is safer than food use. Products differ, and their labels may make claims without establishing that they benefit kidney health.
What if you already use it in cooking?
There is usually no reason to treat a small amount in a dressing or other food as though it were a medical treatment. Consider the whole recipe: a salty sauce, for example, may be more relevant to your kidney plan than the vinegar used to flavour it.
If you have been given a specific dietary restriction, ask your renal dietitian about the foods you actually eat. Food use and a daily “dose” marketed to lower creatinine are separate questions.
Is vinegar water better than plain water for CKD?
There is no evidence that adding apple cider vinegar makes water a CKD treatment. If you have been advised to restrict fluid, vinegar water still counts as fluid.
Plain water is often a simple everyday choice for people who have not been given a fluid limit. But the amount of water that suits you depends on your kidney condition and other health factors. Neither plain water nor vinegar water should be forced in large amounts to try to improve a blood test result.
Our guide to drinks for kidney health when creatinine is high explains how to consider beverages, ingredients, and fluid limits together.
Should you take it if you receive dialysis?
Do not add a daily vinegar drink as an attempt to clean your blood or reduce dialysis needs. Dialysis has a defined medical purpose that vinegar cannot replace. Any drink you consume may also need to be counted in your prescribed fluid allowance.
If you receive dialysis and want to use vinegar in food, ask your renal dietitian how the meal fits your plan. If someone has recommended vinegar for a medical purpose, show your dialysis team the exact product, amount, and claim.
Our guide to supportive approaches during dialysis focuses on food, movement, symptom support, and treatment safety.
Can you take it with kidney medicines?
Your clinician or pharmacist is the right person to review a product you plan to take regularly. Tell them about all prescribed medicines, over-the-counter products, and supplements—not only those you think are “for the kidneys.”
Be particularly cautious about advice to replace a prescribed blood pressure or diabetes medicine with a vinegar routine. Managing these conditions can be an important part of protecting kidney health. If a prescribed treatment is causing problems, ask the clinician who prescribed it to review the plan.
How should you evaluate a kidney-health claim?
Before trying any product marketed to people with CKD, ask:
- What exact outcome is promised? A change in flavour, a change in a blood test, or treatment of kidney disease?
- Was that outcome studied in people with CKD?
- How was kidney health measured? Did researchers examine eGFR, urine albumin, or meaningful health outcomes?
- What else changed? A testimonial may omit medicines, illness, or other care.
- What are the risks for me? Consider your fluid instructions, medicines, and other conditions.
- What necessary care might I delay?
This checklist works for apple cider vinegar, herbal teas, powders, and other “kidney cleanses.” A confident advertisement cannot answer these questions for your personal diagnosis.

What actually deserves attention in a CKD plan?
Start with information your care team can use: the cause of your kidney disease, changes in eGFR, urine albumin, blood pressure, and any diabetes or heart condition. Ask which results matter most for your treatment.
Your plan may involve prescribed medicines, managing blood pressure and glucose, suitable food choices, activity, and avoiding medicines that can harm your kidneys. The appropriate combination varies by person.

Keeping the focus on a diagnosis helps you avoid spending time on a drink that promises an easy fix but cannot tell you why your kidney results changed.
When should you seek medical advice instead of trying a remedy?
Contact a clinician if a kidney test has changed unexpectedly, your urine output changes substantially, you develop new swelling, or you feel unwell. Symptoms such as severe pain, visible blood in the urine, or fever need assessment rather than a vinegar drink.
Seek urgent medical help for severe difficulty breathing, chest pain, fainting, or other serious new symptoms.
If you already have an appointment for an abnormal result, keep it. A home remedy should not delay follow-up testing or treatment.
Frequently asked questions
Can apple cider vinegar cure kidney disease?
No good evidence shows that it cures CKD or restores permanently damaged kidney tissue. Treatment depends on the cause of kidney disease.
Will drinking it lower my creatinine quickly?
There is no reliable evidence that apple cider vinegar treats a high creatinine result. Ask your clinician why the result is high and whether follow-up tests are needed.
Is it okay to put apple cider vinegar on food?
A small amount used for flavour is a different choice from drinking it daily as a treatment. Consider your overall meal plan and ask your renal dietitian if you have specific restrictions.
Does “organic” apple cider vinegar work better for kidneys?
An organic label does not establish a benefit for CKD, creatinine, or eGFR. The treatment claim still needs evidence.
Can I mix it with lemon or honey?
Adding ingredients does not make vinegar a kidney treatment. Honey adds sugar, which may matter if you have diabetes. Any drink still counts toward a prescribed fluid limit.
Is it safer than a kidney medicine because it is natural?
“Natural” does not mean effective or risk-free. Prescribed treatments have a defined purpose in your care plan; discuss side effects or concerns with your clinician rather than replacing them.
The takeaway
Apple cider vinegar may have a place as a food ingredient. It does not have an established role as a treatment that lowers creatinine, reverses CKD, or replaces medical care. Regularly drinking it also raises questions about acidity, dental health, your medicines, and any fluid instructions you follow.
If a kidney result worries you, find out what it means before trying to change it. That conversation is more valuable than a “kidney cleanse” recipe.
