cranberry juice side effects

There are many possible side effects of cranberry juice. These include: Diarrhea, Kidney stones, Gastritis, and Diabetes. These side effects can be dangerous so be aware before you start taking any new supplement. However, in many cases, these side effects are not serious enough to warrant immediate withdrawal.


Cranberry juice contains a natural salicylate, which can reduce the amount of Enterobacteriaceae in the digestive tract. This type of bacteria is common in people with digestive problems and is responsible for constipation. Cranberry juice helps to retain water in the colon which makes the stool compact.

Kidney stones

Cranberry juice is good for the urinary and bladder functions, but for some people, drinking cranberry juice can cause kidney stones. These stones are caused by calcium buildup in the kidneys. These stones can be painful and cause nausea and sharp pain in your abdomen.


One recent study looked at the effects of cranberry juice on type 2 diabetes patients’ blood glucose levels. It found that the juice improved fasting glucose levels and improved some biomarkers of oxidation and inflammation. However, the results were not statistically significant.


Cranberry extract powder has been shown to suppress the growth of the bacteria that causes peptic ulcer and gastritis. It also inhibits gastric cells from secreting interleukin-8 (IL-8). Numerous studies have shown that cranberry can reduce stomach cancer rates in humans.

Dental plaque

Dental plaque can be prevented by the antimicrobial polyphenols found in cranberry juice. These compounds prevent the formation of plaque-forming enzymes, and stop bacteria sticking to tooth surfaces. This is similar to what you see with black tea.

Skin health

Cranberry juice contains an abundance of vitamin C, which helps the skin stay healthy. This vitamin is linked to the production of collagen, a substance that gives the skin its structure. It protects against UV light damage and helps to prevent the aging process.


A recent study has shown that drinking cranberry juice can reduce the risk of cancer. It showed that a polyphenol rich extract in cranberry juice reduced the viability of cancer cells. This substance is likely composed of anthocyanins and proanthocyanidins, which are high molecular weight polyphenolic compounds.
