It should be 100% juice with no sugar added. There are brands out there that sweeten the taste with a bit of apple juice mixed so that it is not so sour (instead of sugar, which only makes matters worse). Also, you can take cranberry pills - all natural. But, the problem with these things is that, once you have a UTI, they really will not help much at all. Lots of water actually helps to flush the urethra and makes it a tiny bit less painful to go to the bathroom. Outside of that, the best thing is to get in to see the doctor as soon as possible. They can even give you medication not only for the UTI but something that actually lessens the pain in that area. Though it will discolor your urine. loll. But hey, it helps.
