The most common alternative remedy used is some type of cranberry supplements. Most often, cranberry products can be found in either juice or a tablet form, and have been shown to work against infections. But you do need to be careful if you’re taking blood thinning medications such as warfarin, as cranberry should be avoided in this case. Other natural remedies for urinary tract infections are supplements such as D-Mannose and Uva Ursi. Vitamin C can also help prevent urinary tract infections.
