The Feel Great System Listed in the PDR: Why That Matters!

Why does it matter that the Feel Great System products are listed in the Prescribers’ Desk Reference (PDR)?

For more than 70 years, the Physicians' Desk Reference (PDR) is consulted by healthcare professionals millions of times each week, and the publication has been distributed to nearly 500,000 physicians and chief pharmacists throughout the United States. 

Ninety percent of healthcare professionals consider this reference their most important source of reliable information—they believe that it helps them make appropriate and informed decisions when it comes to advising their patients on which products to use. The PDR was also made available in libraries and bookstores, widely used by other medical specialists, and sometimes referenced by consumers.

While designed to provide physicians with the full legally mandated information relevant to writing prescriptions (just as its name suggests), it later began adding nutraceuticals that were science-based and backed by peer-reviewed clinical studies. In 2002, Unicity Balance (formally called Bios Life 2) was the first natural product to be listed in the PDR.  

The 71st Edition, published in 2017, was the final hardcover edition. It weighed in at 4.6 pounds and contained information on over 1,000 drugs. Since then, the PDR has been renamed to Prescriber's Digital Reference (PDR), because not all prescribers are physicians and the reference is no longer a hardback book stored on a desk.

Today the PDR is available online ( for free, and has been integrated into some electronic health record (EHR) systems. also links to a free mobile app. The PDR continues to be a compilation of manufacturers' prescribing information (package insert) on prescription drugs, updated regularly and published by ConnectiveRx.
