Although the Protazen® Base Formula is a comprehensive single bottle solution, Protazen® is the only brand to recognize that one size does not necessarily fit all, when it comes to people's mental health. Some customers may find the need to take a more focused approach to address specific concerns. For these people, we offersix additional productsthat are designed to work in concert with the Protazen® Base Formula. You can take as many or as few as you find necessary. Theseadditional productswill allow you to customize your regimen and take a more focused approach, if necessary.
