Ease Gastrointestinal Disorders and Vaginal Infections with Acidophilus 

"Bad" bacteria makes you sick; "good" bacteria" like acidophilus helps you stay healthy.  Add some acidophilus, or probiotic bacteria, to your diet if you are prone to digestive upsets, constipation, irritable bowel syndrome, diarrhea, and urinary tract infections; or yeast infections and vaginal infections in women.  You will be pleasantly surprised to find that it will reduce the incidence and the duration of these problems.
 
Because taking antibiotics or undergoing radiation will destroy the useful bacteria housed by the body that normally protects against yeast and vaginal infections, it is especially important to have acidophilus supplements on hand to replace this natural protection.  Other benefits of this "good" bacteria is that it reduces flatulence, mitigates travelers complaint, or diarrhea associated with impure water and food, neutralizes e-coli bacteria, and helps combat bad breath associated with digestive disorders.  The job of these supplements is to protect the health of, and maintain the normal balance of, bacteria in the intestines and the vagina.
 
A natural source of acidophilus is yogurt, but check the label as some brands carry little or none of it.  Supplements are much more reliable and are in the form of tablets, capsules, and powders, and you can also find it in liquid form or available as a douche.  There are no recorded adverse reactions to probiotic bacteria.
