“I really miss Dr bob Marshall...and all his radio programs...IF somehow those can be replayed and is there any older doctors that can pick up the slack for what Dr Marshall did with his practice. I feel it would be what is needed for the prodcuts to continue to thrive...Jana is my "go to" person when i call in and she is marvelous...I also appreciated Dwight years ago and sad to see so many good QNL people go...I'm sure there is a new group. I would like to have practioner numbers available more easily to access online.”

Thank you for sharing this. Dr. Bob Marshall had a profound impact on so many people, and it’s clear his teachings and radio programs still mean a lot to you. We appreciate you being part of QNL for so long and recognizing the support you’ve received from Jana and others over the years. Your feedback about practitioner access is also helpful, and we understand how important it is to have that information easy to find. We’ll be sure this gets passed along to the team for review.

“I am always pleased when ordering from Quantum. I have primarily ospoken to Brandon when not using your online services. He is consistently professional, knowledgeable and efficient. I have also been very satisfied with the QNL products, and have been sad when some were discontinued.”

“For 25 years QNL has been a big part of my healthy lifestyle. These products are the most pure and also within the level of product, affordable supplements. I am 71 years old, taking no medication for anything, unlike anyone else that I know in my age group. I am guilty of not doing all that I know to do as to a more substantial healthy lifestyle, more raw foods, making fresh juice...BUT the time it takes...leads me to the best possible supplements: QNL”

“I have been loyally using your Kidney Support for years and my numbers have remained the same. I stopped ordering late in 2025 when the price went up to $47.00 a bottle, quite an increase. I did reorder recently when a 30% discount was offored although I only ordered 2 bottles. With deep discounts I will order again but not at $47.00 a bottle.”

We understand the price can be a factor, so it’s great you were able to take advantage of the 30% promotion. That’s often the best time to stock up.
