Supplements for Kidneys & Bladder

Our kidneys filter the blood and remove waste materials from the body. They also help to regulate blood pressure, maintain electrolyte balance and blood pH levels. The bladder supports the kidneys by holding urine and facilitating urination.

Urinary Tract Infections (UTIs) are an extremely common condition affecting the bladder, urethra and kidneys. Symptoms include an urgent need to urinate, pain on urination, unpleasant odour of the urine, cloudy or dark urine (sometimes it may contain blood), lower abdominal pain and pain during sexual intercourse. UTIs are common in women and according to Kidney Research UK, approximately 50% of women in the UK have had a UTI. Drinking enough fluids, limiting alcohol, urinating when required, addressing constipation and wiping from front to back can help to reduce the risk of UTIs.

Kidney function can also be affected by kidney stones or chronic conditions including diabetes, high blood pressure or liver disease, as well as exposure to toxins. However, there are a number of foods and nutrients that can help to support kidney and bladder health.

Key Foods for Kidney and Bladder Health

Fibre, magnesium, vegetable proteins, sufficient fluids and probiotic foods can all help support kidney function, reduce constipation and protect against kidney stones and UTIs. Try to include the following foods for optimal kidney and bladder health.

  • 30g fibre per day - include fruits, vegetables, nuts, seeds, legumes and wholegrains such as oats, brown rice and quinoa in your diet. These foods also have important antioxidant and anti-inflammatory properties to support healthy cells and tissues of the kidneys and bladder.
  • Magnesium is found in dark green leafy vegetables, nuts, seeds, legumes, avocados, bananas and cacao.
  • Vegetable proteins include lentils, peas, beans, tofu, buckwheat, quinoa, nuts and seeds.
  • Sufficient fluids - drink between 1.8-2.4L daily with at least 50% of this being water. Include unsweetened cranberry and blueberry juice if you are susceptible to UTIs.
  • Probiotic foods such as unpasteurised sauerkraut, yoghurt, cottage cheese, tempeh, kimchi and miso can help to support the gut-kidney axis.
