This is amazing I had parathyroid surgery a few years ago and I’m have to take a good calcium I found the calcium magnesium powder is the best. It goes a long way. I feel much much better and my numbers have been all good.

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 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 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.
