Thanks for taking the time to leave a review Kerrin! Be well! MSI
I want to thank you for your prompt service. I think people sometimes forget to say something when things are good. My orders are quick and correct. My clients never have to wait long and are normally surprised when I call saying their product is here. Thank you it helps make things run smooth on my end

My product arrived faster than I expected and it was packaged extremely well to protect the product in shipping. The nutritional supplement also comes in a dark-colored glass bottle which protects the supplement from UV light.

I have been giving my whole family the Theralac probiotic everyday for the past week. That has made all of us more regular in our bowel movements everyday. It even helps the dog not frantically bite/lick her paws. A dog licking their paws means that their digestion is off and they are crying for help. My dog is so much more relaxed now that she has Theralac!!!
