Natural supplements and the practice of naturopathy aim to enhance internal defences against infection. Naturopathy “remedies” are made from natural sources (e.g. plants or minerals).  However do they actually work for urinary tract infections?

Buyer beware

Most supplements are available in health food stores, homeopathic pharmacies and online. However, before heading to your local health food store or searching online for suppliers, please consider the following:

  • Unlike allopathic medications, little research has been published for these remedies illustrating their efficacy against acute, recurrent and chronic UTI and in particular against biofilms and embedded bladder wall infections of the urinary tract.
  • Research produced may often by supported by companies that manufacture or promote a particular product. Make sure you look for independent studies free from financial support bias.
  • Treatments are often unlicensed and lack the safeguards in place for conventional therapeutics.
  • Controlled trials and studies are often limited in complementary and alternative medicine and involve small numbers of participants. They are often conducted under less rigorous controls, governance and environments than those undertaken for the development of new pharmaceutical medications such as antibiotics. Do your research, there should be clear, peer reviewed, empiric evidence as to the efficacy of complementary therapies rather than theorisation about how they may be beneficial in the treatment of a chronic UTI.
  • Don’t believe all apocryphal stories you read online about how a natural remedy or home treatment has resolved someone’s UTI issues. Remember, the bacterial mix in that person’s infection may be entirely different to yours and they may be paid to promote that product.
  • There appears to be no global consensus around dosages and length of treatment.
  • Natural remedies are often not standardised in terms of quality and manufacturing controls
  • Thus natural remedies are omitted from evidence based guidelines because of this lack of evidence supported through randomised control trials. More trials and studies are needed.

Cranberry Juice – not the cure-all for cystitis

For example, consider the widely recommended usage of cranberry as a cure all for a UTI. Published studies focusing on juices, tablets and powders incorporate a wide age range from college students to those in nursing homes.  A detailed review published in Jama Internal Medicine in 2012 of 13 Randomised Control studies out of a total of 414 studies then available noted the following:

Cranberry juice – the case against

These detailed review results appear to give no guidance to the reliability of cranberry products against UTI because of the factors outlined above. The National Institute for Clinical Excellence (NICE) in the UK recommend against the usage of cranberry products for those with recurrent urinary tract infections. NICE report in their guidelines from 2018 for those with recurrent UTI “evidence of benefit is uncertain and there is no evidence of benefit for older women”.  NICE guidelines for acute cystitis in 2018 state “Be aware that no evidence was found on cranberry products or urine alkalinising agents to treat lower UTI”.

In an article published in The New York Times in 2016, it was concluded that cranberries are not the answer for an active infection.
