Your body relies on the entire renal system, particularly the bladder and kidney, to get rid of toxins that enter the body. Factors like diabetes, smoking, drinking alcohol, drug use (recreational and medicinal) can all harm this system. Over time the effects they have on your bladder and kidney are incredibly deleterious, and you can fight back against those harmful effects with the right kind of supplements. These are supplemetns that help your kidneys to filter more effectively and that reduce the workload the renal system has to deal with. One example of this is celery extract, which can help your body retain fluids better, while cranberry supplements keep bacteria from taking hold on the urinary tract, preventing infections. Horsetail is excellent for providing relief to the urinary system when there is an infection.
