Review

My husband and I have been using OPC-3 for almost 20 years....obviously, we have been happy with it. Sure would like an easier way to dispense it.

Response from Customer Service:

Thank you so much for your wonderful feedback and for being loyal users of Isotonix OPC-3® for almost 20 years! We’re delighted to hear that you and your husband have been happy with the product. We also appreciate your suggestion for an easier way to dispense it and will be sure to share your input with our product team. In the meantime, we recommend poking a hole in the middle of the inner seal for better pour control, it can make measuring and pouring much easier. Thank you again for your continued support!
