Cranberry Juice Will Clean Out Your System
Cranberry juice can help you detoxify your body. It has properties that prevent bacteria from adhering to your urethra, for example. It also has high quantities of vitamin C, so is a great part of a healthy detox diet.
It Will Not Eliminate Traces from Your Urine
While the cranberry juice can help speed up your metabolism, it cannot help you clean out your system in a hurry. You cannot pass a urine test for alcohol or other drugs by taking a heavy dose of cranberry juice beforehand.
While cranberry juice is good for your metabolism and a good way to help treat a urinary tract infection, it will not clean traces of alcohol out of your system. It can help detoxify your body over the long haul, but is not a quick fix.
