cranberry juice side effects

There are many possible side effects of cranberry juice. These include: Diarrhea and 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 is rich in natural salicylates, which can help reduce the amount of Enterobacteriaceae. This type of bacteria is commonly found in people with digestive issues and is responsible for constipation. Cranberry juice also helps the body retain water in the colon, which makes the stool more compact.

Kidney stones

Although cranberry juice is good for the bladder and urinary functions, it can also cause kidney stones in some people. These stones are caused by calcium buildup in the kidneys. They are painful and can cause nausea and sharp pain in the abdomen.


A recent study examined the effects of cranberry extract on blood glucose levels in type 2 diabetic patients. The juice was found to improve fasting glucose levels as well as some biomarkers of inflammation and oxidation. However, the results were not statistically significant.


Cranberry extract powder has been shown not to cause gastritis or peptic ulcer. It also inhibits gastric cells from secreting interleukin-8 (IL-8). Several studies have shown that cranberry can also reduce the rate of stomach cancer in humans.

Dental plaque

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

Skin health

Vitamin C is a key ingredient in healthy skin. Cranberry juice is rich in vitamin C. 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.


Recent research has shown that cranberry juice may reduce the risk of developing cancer. It was found that cranberry juice contained a high amount of polyphenols, which reduced the viability and viability of cancer cells. This substance is likely to be composed of proanthocyanidins and anthocyanins, which are high molecular-weight polyphenolic compounds.
