I started using this product when I became an ambassador for this brand, they give you credit towards a product each month, so I chose these probiotics because I frequently have bacterial infections.. Since taking these, I haven't had any infections! I can honestly say that this product is a life saver! & I probably never would of found them if it wasn't for their ambassador program & being accepted into it! I feel like it was meant to be.❤ I have heard very highly about Pure Encapsulations' other products as well! Can't wait to try others! This brand is serious about quality! & I LOVE that they are clean also! I highly recommend this product & this brand without a doubt!
