Thank you, Nicholas. We take them daily too.
Love the products but the shipping is interesting. Sometimes I am not home to sign for the shipment so it is sent to another place to go pick up. Very inconvenient.

Thank you for the feedback Babbye. We are happy to send your shipment to your work address if you prefer. We do require signature for delivery as we don't want shipments left on doorsteps or mailboxes due to the extreme number of porch pirates and mail theft in the DFW area. I too live in the metroplex and we have so much reported thefts on the ring and nextdoor app. It truly is infuriating to watch how brazen humans are stealing mail and parcels.
The Probiotic I purchased was shipped to me very quickly. I don't know how the product is affecting my body, but I assume it is doing me good.

Thank you, Thomas. Let us know if you have any questions after you give the product a try.
I love y’alls!! Very good stuff!! Please bear with me!! I will order more in the near future.... I just recently got done relocating out of Alaska, back to the continental USA to be closer to family. So please do not be offended with the fact I have not ordered in some time. I am working at getting my finances together. I absolutely LOVE LOVE LOVE everything I have ordered from y’alls, and I can guarantee you I will order more in the near future. Your products are kinda pricy, but please understand that I understand it’s money well spent. Thank you for being so amazing, and thank you for your patience. God Bless, SpaceNinja USAF Veteran

So happy to hear of your satisfaction. Thank you for your service and let us know if we can assist you further, Emily.
I am so pleased with the Essntial Formula probiotic products I have been using. Dr. Ohirras formula works great ! I was suffering from gastrointestinal complications accompanied by constipation and incomplete stool passing. After 2 weeks of using this product, I began to notice a positive change in my stomach function. After 30 days, I feel like a different person ! No gas, no constipation, no irritability, no excess stomach pressure! All of it gone ! I have been using the product for almost 60 days now and I can assure you.... It’s Life changing !
