True as advertised no stains in toilet, which was my concern. Green pee and poo but no stains. I also took an extra vitamin C tablet with the MB capsule just to be sure. Very satisfied with this product. It was shipped and delivered to my mailbox, so check your mailbox if the walmart app says delivered but you don't see it at your front door!

Hello Gabriela! So glad you are very satisfied! It’s 'true as advertised'—you get the benefits with no stains in the toilet. We appreciate you sharing your experience with the MB capsule and Vitamin C, as well as the helpful reminder to check the mailbox if the front door is empty. Enjoy the product!

Mental Boost

It's been great for my mental clarity during long work days. The fact that it's vegan and doesn't have any artificial additives makes me feel good about using it regularly. 😊

This is a great product! I felt mental clarity and I was less forgetful since I have been taking this. It is fun to me since it turns my pee a teal blue color...lol Good stuff! 🤩

Hello Yolanda! "Thank you for the fantastic feedback! We are so happy to hear that this is a great product for your routine and that you felt mental clarity and were less forgetful since you have been taking this. That teal blue color is a completely normal (and entertaining) sign of the supplement's purity and excretion. Glad you’re enjoying the results!"
