Cranberry and urinary tract infections: what the evidence shows, and what notices questioned

This article is general information, not medical advice. Cranberry products have been studied for preventing urinary tract infections. They are not a treatment for an infection you already have, and a claim on a capsule is not the same thing as the trials. If you have symptoms, are pregnant, are asking about a child, or have a kidney problem, see a doctor. Any supplement is only as that doctor advises.

Three reports on 19 October 2026 describe notices about cranberry capsules. The companies are not named on this page. The links below name them, so a reader can see the reports. The same day's reports also describe a fruit-juice label. That is a separate reading: How to read a packaged juice label. How "no added sugar" was read on nutrition drinks is in Pregnancy and breastfeeding nutrition drinks.

What the reports say the notices questioned

CNBC-TV18, 19 October 2026, describes notices on two cranberry capsule products. On one, it says the regulator flagged discrepancies in food-colour declarations on a marketplace listing and on the company's own website, questioned a "supports urinary tract health" claim, and questioned use of the FSSAI logo alongside claims that suggested an approval. On the other, it says the product was marketed under an expired registration certificate. It says claims on urinary tract health, kidney health, and the prevention or relief of urinary tract infections were flagged, and that such disease-risk-reduction and health-related claims required prior approval. It also says advertisements suggesting benefits related to skin, weight loss, dental and heart health, kidney function and detoxification were raised. Both companies, the report says, were directed to respond, and an unsatisfactory response could lead to further action.

NDTV Profit describes the same two capsule notices. It says one flagged urinary tract health, kidney health and prevention or relief of urinary tract infections, with those claims said to need prior approval, and an expired registration certificate. It says the other flagged colour-declaration discrepancies, labelling issues, and claims such as "Supports Urinary Tract Health" and "100% Natural", plus the FSSAI logo and phrases that presented the product as officially approved.

India Today, 19 October 2026, describes notices on the same kind of products: an expired registration certificate, potentially misleading disease-related claims, use of the logo in a way that could imply an endorsement, labelling discrepancies, and claims that required prior approval. It says the companies have been directed to respond or to take the action specified in the proceedings. It also says notices alleging violations, and the start of proceedings, should not be treated as final findings of liability.

This page has not seen the notices, the labels or the listings. It does not decide which wording was on which pack. A notice is not a completed penalty. Nothing here is a finding that a capsule does, or does not, affect the urinary tract.

What the Cochrane review measured

The Cochrane review, Williams and colleagues, published 10 November 2023, is the fifth update of a review first published in 1998. The search ran to 13 March 2023. The objective is to assess cranberry products for preventing urinary tract infections in susceptible populations. The plain-language summary says cranberries contain proanthocyanidins, substances that can prevent bacteria from sticking to the bladder wall. It also says there is currently no established regimen for the dose of those substances, no formal regulation by health authorities of cranberry products, and that the dose suggested may not be on the package.

The review included 50 randomised or quasi-randomised trials and 8,857 people. Forty-five trials compared a cranberry product with placebo, water or no specific treatment. Twenty-six of those 45 could be combined for symptomatic, culture-verified infections. In moderate-certainty evidence, cranberry products reduced the risk: 6,211 participants, risk ratio 0.70, 95 percent confidence interval 0.58 to 0.84. The trials disagreed with each other more than chance would suggest (I² = 69 percent). A risk ratio below 1 means fewer of those infections in the cranberry groups of the trials that were pooled. It is not a guarantee for one person, and it is not a result for an infection that has already started.

Where the benefit showed, and where it did not

When the trials were split by the reason people were in them, the review says cranberry products probably reduced symptomatic, culture-verified infections in three groups:

Women with recurrent infections: 8 studies, 1,555 participants, risk ratio 0.74, 95 percent confidence interval 0.55 to 0.99.
Children: 5 studies, 504 participants, risk ratio 0.46, 95 percent confidence interval 0.32 to 0.68.
People susceptible because of an intervention, the example given being bladder radiotherapy: 6 studies, 1,434 participants, risk ratio 0.47, 95 percent confidence interval 0.37 to 0.61.

The authors' conclusion says these data support use in women with recurrent infections, in children, and in people susceptible after interventions. The same conclusion says further assessment in well-designed, prospectively registered trials is required to clarify who would benefit.

In three other groups, the review's wording is little or no benefit:

Elderly institutionalised men and women: 3 studies, 1,489 participants, risk ratio 0.93, 95 percent confidence interval 0.67 to 1.30, moderate certainty.
Pregnant women: 3 studies, 765 participants, risk ratio 1.06, 95 percent confidence interval 0.75 to 1.50, moderate certainty.
Adults with neuromuscular bladder dysfunction and incomplete emptying: 3 studies, 464 participants, risk ratio 0.97, 95 percent confidence interval 0.78 to 1.19, low certainty.

The authors' conclusion says the evidence currently available does not support use in the elderly, in patients with bladder emptying problems, or in pregnant women. The results section's older-adult trials are the institutionalised ones. This page leaves both wordings as printed.

Against antibiotics, the review says cranberry products may make little or no difference to symptomatic, culture-verified infections (2 studies, 385 participants, risk ratio 1.03). Against probiotics, it reports a lower risk (3 studies, 215 participants, risk ratio 0.39). The plain-language summary says there was not enough information to determine whether cranberry products are more or less effective than antibiotics or probiotics. This page does not pick the smaller comparison over that summary. It also says the certainty was very low for whether juice differs from tablets, and for whether different doses of proanthocyanidins differ. No difference in infection risk was demonstrated between low, moderate and high doses.

Gastrointestinal side effects probably do not differ between cranberry products and placebo or no treatment (10 studies, 2,166 participants, risk ratio 1.33, 95 percent confidence interval 1.00 to 1.77, moderate certainty). The plain-language summary says few people reported side effects, the most common being stomach pain.

A capsule is not care for an infection you have

Nothing in that review is a treatment protocol. Symptoms need a clinician. That includes pregnancy, children, and anyone with a kidney problem. The finding in children is a research result about prevention in the trials that enrolled children. It is not an instruction to give a child a capsule. The health-supplements regulations, below, say supplements of that category may be used to supplement the diet of a person above the age of five. That is a regulatory sentence about who the category is written for. It is not medical clearance.

The Cochrane summary also says there is no established dose, and that the dose may be missing from the pack. This page will not supply one.

What the rules say a supplement label may not do

Two compilations were opened. The gazette prevails if a line in either compilation differs.

Regulation 6(3)(i) of the Health Supplements, Nutraceuticals and related regulations, compendium dated 29 September 2021, says the labelling, presentation and advertisement shall not claim that the health supplement has the property of preventing, treating or curing a human disease, or refer to such properties. Every package is also to carry "HEALTH SUPPLEMENT", an advisory warning "NOT FOR MEDICINAL USE", a statement that the supplement is not to be used as a substitute for a varied diet, and a statement that the product is to be stored out of reach of children.

The same compendium lists cranberry. In the schedule of nutraceutical ingredients opened here, item 187 is Vaccinium oxycoccos / Vaccinium macrocarpon, cranberry fruit, as a dried powder or a standardised concentrate. A place on that list is an ingredient entry. It is not a urinary-tract claim, and the row read here does not print a dose this page can repeat.

Clause (27) of the general provisions in that compilation is about cereal grains, legumes, fruits and vegetables that are in the Indian food tables, and about spices on the Spices Board list. It says those foods may be used as a supplement or nutraceutical as applicable, and that a claim of specific health benefits needs prior approval. This page did not find a cranberry row in the Indian food tables, so it does not treat that clause as the cranberry rule. The schedule entry above is the line that names the fruit.

In the Advertising and Claims compendium dated 14 December 2022, regulation 7(3) says no reduction-of-disease-risk claim shall be made that is not in accordance with Schedule III. Schedule III, as opened, lists eight relationships, beginning with calcium and osteoporosis, sodium and blood pressure, and fats and cholesterol. There is no urinary-tract row and no cranberry row. Regulation 11 says the operator or marketer shall seek prior approval for reduction-of-disease-risk claims other than those defined, with criteria, in these regulations or in another regulation under the Act. Regulation 10(1) prohibits claims that a food is suitable to prevent, alleviate, treat or cure a disease, disorder or particular physiological condition, unless another regulation specifically permits it.

A "supports urinary tract health" line, and a line about preventing or relieving infections, are the kind of wording the news reports say was questioned. Whether a particular pack needed prior approval is for the notice and the reply. This page has not seen either. It does not turn the Cochrane risk ratios into a permitted Indian label claim.

Schedule V of the advertising compendium says a composite food shall not itself be described as "natural", though it may be described as "made from natural ingredients" if every ingredient meets the schedule's tests. NDTV Profit says a "100% Natural" line was among the claims flagged. "Natural" and "100 percent" are different words. The fruit-juice reading linked above is where the "100 percent" advisories are set out. They are not a cranberry dose.

Juice, sugar, and a different food

A sweetened cranberry drink is not the capsule in a notice, and it is not automatically the product in a trial. The review included juice, tablets and capsules, and then said it is unclear whether juice and tablets differ. The Dietary Guidelines for Indians say, on the My Plate note, to prefer fresh fruit and avoid juices. They restrict added sugar to 25 to 30 g a day where sugar is used. This page did not find a cranberry-juice sugar figure it can print, so it does not invent one.

A claim that sugars have not been added has its own conditions in regulation 6 of the advertising compendium: no sugars of any type added, no ingredient that contains sugars as an ingredient, no ingredient that substitutes for added sugars, and no increase in the food's own sugars by some other means. If sugars are naturally present, the label also carries "CONTAINS NATURALLY OCCURRING SUGARS". Those conditions are about the words on the pack. They are not a finding that a cranberry drink is low in sugar.

The trials that exist are about preventing symptomatic, culture-verified infections, in some groups and not in others, with no established dose on the package. A capsule that promises urinary tract health, or relief of an infection, is a claim the October reports say was put to the companies. It is not care for symptoms you have today.

Questions

What did the 19 October 2026 reports say was flagged?

CNBC-TV18, NDTV Profit and India Today, all on 19 October 2026, describe notices about cranberry capsules. They say the regulator questioned claims on urinary tract health, kidney health, and prevention or relief of urinary tract infections, and that disease-risk-reduction and other health claims of that kind needed prior approval. CNBC-TV18 also says advertisements suggesting benefits for skin, weight loss, teeth, the heart, kidney function and detoxification were raised. One notice, the reports say, included an expired registration certificate. Another included discrepancies in colour declarations and use of the FSSAI logo next to approval-style wording. NDTV Profit also names a "100% Natural" line. The companies were told to respond. India Today says notices and the start of proceedings should not be treated as final findings of liability. This page has not seen the notices.

Who did the Cochrane review find may benefit?

The review, published 10 November 2023, included 50 randomised trials and 8,857 people. For symptomatic, culture-verified infections, cranberry products probably reduced the risk in women with recurrent infections (8 studies, 1,555 people), in children (5 studies, 504 people) and in people susceptible because of an intervention such as bladder radiotherapy (6 studies, 1,434 people). The authors say the evidence supports use in those three groups. They also say further well-designed trials are needed to clarify who benefits. A child, a pregnant woman, or anyone with symptoms still needs their own doctor. This page is not a dose.

Who did it find may not benefit?

In moderate-certainty evidence, there may be little or no benefit in elderly institutionalised men and women (3 studies, 1,489 people) or in pregnant women (3 studies, 765 people). In low-certainty evidence, there may be little or no benefit in adults with neuromuscular bladder dysfunction and incomplete bladder emptying (3 studies, 464 people). The authors' conclusion says the evidence does not support use in the elderly, in patients with bladder emptying problems, or in pregnant women. The institutionalised subgroup and the word "elderly" in that conclusion are both printed. This page does not widen either sentence to every older adult.

Can cranberry treat an infection I already have?

The review assessed prevention. Its objective is the effectiveness of cranberry products in preventing infections in susceptible people. It is not a trial of treatment for an infection that is already present. Pain, burning, fever, blood in the urine, or symptoms in pregnancy, in a child, or with a kidney problem, are a reason to see a doctor. A capsule is not that visit. Supplements, if any, are only as your doctor advises.

Does a listing in the nutraceutical schedule permit a urinary-tract claim?

The health-supplements compendium lists cranberry fruit, as a dried powder or a standardised concentrate, under the botanical names Vaccinium oxycoccos and Vaccinium macrocarpon. That is an ingredient entry. The same regulations say the labelling, presentation and advertisement of a health supplement shall not claim the property of preventing, treating or curing a human disease, or refer to such properties. Schedule III of the advertising regulations, which lists permitted reduction-of-disease-risk claims, has no urinary-tract row in the text opened for this draft. Other reduction-of-disease-risk claims need prior approval under regulation 11.

Is this medical advice?

No. It is a reading of three news reports, a Cochrane review, the advertising-claims compendium and the health-supplements compendium. It is general information, not medical advice. A named dietitian has not reviewed this draft. It is not a product review, and it does not tell you to buy or avoid a capsule.
