I buy these online for my one female who frequently gets UTI's. Since she's been taking them she's not gotten another infection! It keeps her phLevels down apparently, and she LOVES eating them. She knows when I get up in the morning that she gets one, and she waits by the kitchen counter to get it! When I come home at night, she knows that she gets the other one, and does the same thing! So glad these are affordable and something she will take!
