Cranberry extract is commonly used in dietary supplements for urinary tract health, as it contains antioxidants like vitamin C and proanthocyanidins.

A study found that cranberry products may reduce the risk of symptomatic, culture-verified urinary tract infections (UTIs) in certain populations, such as women with recurrent UTIs and children without neurogenic bladders. Cranberry products may also cause mild gastrointestinal side effects.

Cranberry extract supports urinary tract health, helps prevent UTIs, and is rich in antioxidants like vitamin C and proanthocyanidins. It promotes digestive health, may improve heart health by lowering cholesterol, and helps oral health by preventing gum disease and reducing harmful bacteria.

Cranberry extract is typically taken in capsule form. Swallow the capsules whole and do not break, chew or crush them to ensure proper absorption and effectiveness. Always follow the recommended dosage instructions by healthcare provider.

Side effects are unwanted symptoms caused by medicines. Although all drugs can cause side effects, not everyone experiences them.

Common side effects of cranberry extract are:

• Upset stomach or mild digestive discomfort
• Diarrhoea
• Mild allergic reactions such as rash or itching

Serious side effects of cranberry extract are:

• Kidney stones (in individuals with a history of kidney stones)
• Severe allergic reactions like difficulty breathing and swelling of the face or throat.
• Increased risk of bleeding, particularly when taken with blood-thinning medications (e.g., warfarin)

• Kidney stones: Cranberry extract may increase the risk of kidney stones in individuals with a history of kidney problems or oxalate sensitivity.
• Blood thinners: It may interact with blood-thinning medications (e.g., warfarin), increasing the risk of bleeding.
• Allergic reactions: Some individuals may experience allergic reactions, such as rash, swelling, or difficulty breathing.
• Pregnancy and breastfeeding: The safety of cranberry extract during pregnancy or breastfeeding has not been well established. Consult a healthcare provider before use.
• Medication interactions: Cranberry extract may interact with certain medications, including those for blood pressure and diabetes. Always check with a healthcare professional before using it alongside other treatments.

When using cranberry extract, follow proper dosage guidelines and consult your healthcare provider if you have any underlying health conditions or are taking other supplements. Pregnant or breastfeeding individuals should seek medical advice to ensure safety. Monitor your body's response, especially if you're new to the supplement or have any sensitivities.
