Is too much orange juice bad for you?

Four to six ounces of unadulterated cranberry juice daily is recommended for the prevention of UTIs. Some herbalists advocate the use of cranberry for treatment of mild urinary tract infections; dosages of 10-32 oz (0.3-1 kg) daily have been used.

A person needs to drink 16 ounces of unsweetened cranberry juice (two glasses) daily to effectively prevent kidney stones. Cranberry capsules or powdered concentrates are also available. It is important not to consume too much cranberry , because very high acidity in the urine actually increases the risk of kidney stones. A person would need to drink at least one liter of cranberry juice per day for a prolonged period of time for this to occur.

Because most commercial cranberry juice contains high levels of sugar, dried cranberry powder capsules (475-500 mg) may be a better alternative for diabetic patients or dieters. Each capsule equals 0.5 ounces of cranberry juice. Nine to 15 capsules daily is the recommended dosage for the prevention of urinary tract infections.
