Started listening to Dr. Bob Marshall when I was in my twenties. Miss him and his knowledge and his reasonable prices.

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 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.

QNL's product quality is top tier, but I am incredibly alarmed at the price increases over the past five years, which seem exhorbitant and borderline criminal to say the least.

We appreciate the honesty. We’re glad you still see the quality in QNL products. Pricing has risen over the past few years due to increased sourcing, manufacturing, and testing costs, and we’ve chosen to maintain our standards rather than lower quality. We value your feedback and your support.

Little disappointed in communication. I wanted to change my delivery date. And I was told to go online and change The date And when I did it automatically increased my HCL $20 more so I stopped before I change the other two.. I called up and the girl who does internet Said she couldn't do nothing about it... Hopefully you can fix that for me and put it back on my automated payment And delivery the way I had it.. Thanks George Greco....2016794935
