“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”
Thank you, Barbara! Twenty-five years is something special, and it really says a lot about your consistency and mindset. We love how you balance real-life practicality with taking care of your health, and we’re honored that QNL has been a part of that for so long.
Thank you, Andy. Glad everything arrived on time and in good shape. Always good when the whole experience, from price to product, comes together like that. We appreciate you choosing QNL!

“For once Quantum had a legit sale on their products! Not hiking them up to make it look like a sale with adiscount. We appreciate the read deal! Dr. Marshall would say good job.”
Thank you for saying that. We’re glad the recent promotion felt straightforward and worth it. That kind of feedback means a lot, especially with the standard Dr. Marshall set. We appreciate you recognizing it.
Thank you, Pam. That’s exactly what you hope for with supplements, being able to actually feel the difference. We’re glad QNL has been that for you and appreciate you sharing that!
“I tried many Brands of nutrition supplements but nothing compares to the quality and effectiveness of QNL , the supplements have the puriest and natural ingredients. No fillers ,or artificial ingredients.”
Thank you, Vince. That kind of comparison means a lot, especially coming from someone who’s tried different brands. We put a lot into keeping our formulas clean and effective, so it’s great to hear that’s coming through. We appreciate you choosing QNL!
“I used to listen to dr bob marshall on the radio and started ordering from QNL years ago. I am happy with your products, however I have been trying to order the d- limonene from you and cannot find it. Will you be restocking this item ? I hope so .”
Thank you for sharing this, Kathleen. It’s great to hear you’ve been with QNL since the Dr. Marshall radio days and that the products have continued to serve you well.
As for D-Limonene, that product has been discontinued. We know that’s frustrating, especially when it’s something you’ve been looking for. We appreciate your understanding and your long-time support of QNL.
“I've been using QNL supplements for many years now. The quality is unsurpassed and they're affordable. Overall, my health has improved with daily use.”
Thank you, Patricia. That kind of long-term experience says a lot. We’re glad the consistency and quality of QNL supplements have made a real difference in your day-to-day health!
Thank you for sharing that, Tina. Dr. Marshall had a lasting impact on so many people, and it’s clear his work stayed with you over the years. We’re grateful you’re still with QNL and appreciate the perspective you shared.
“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.”
Thank you for sharing this, Ray. We appreciate your long-time trust in Quantum Kidney Support and are glad it’s been consistent for you over the years. 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.
“Would love it if QNL gave quarterly or yearly discounts for loyal customers. Bob Marshall have reasonable prices for the suppliments but now the prices are very high. I don't purchase half of what I use to. Seems like QNL has gone downhill :(.”
Thank you for sharing your thoughts, Sheila. We understand how pricing changes can affect what people are able to purchase, and we appreciate you being honest about it. We do currently have a 30% off sitewide promotion with free shipping, which can be a great time to restock on the products you rely on. We truly value long-time customers like you and appreciate your continued support of QNL.
Thank you, Ivan. That’s a strong statement and we don’t take it lightly! We appreciate your confidence in QNL and are glad the products continue to deliver for you.
“I trust the quality of the products. I have an issue with products shipping on the same day but I’m not being invoiced on one invoice and have been charged double shipping.”
Thank you for bringing this up, Linda. We’re glad to hear you trust the quality of the products! Our customer service team has been made aware of the shipping concern and will be reaching out to you to look into it. We appreciate you letting us know.
Thank you for sharing that, Bernadette. We definitely understand how that timing can feel frustrating. Our promotions do rotate throughout the year, so hopefully the next one lines up a little better for you. We appreciate you choosing QNL and hope you enjoy the products from your recent order.
