Love the Product

This is second time I have ordered the Brewers yeast. It is better Quality than any other that I have ordered before. I use it for my dogs and myself for keeping fleas away. It works so much better than the brand I was using. There Quality is better by far. Recommend highly.

Product looks good. No bugs in it . But did find roach's in the box that it was packaged in. And I understand roach's love cardboard. So this can happen. I wish that the box's were treated so they did not carry the roach's to my home. I opened it outside and am glad that I did.

got this product in two days. good company to deal with, and would do business with again. FWIW, i bought this as a dog food supplement, as the brewers yeast repels fleas and ticks.
