A fulfilling and vibrant life is rooted in authenticity and trust, ultimately shaping one’s reputation. QNL has embraced this philosophy and distinguishes itself from its competitors by differentiating between regular and whole food supplements. I am genuinely grateful to have been introduced to QNL by my mentor and will always appreciate that recommendation.

I have come to trust the efficacy and the quality of your components in your supplements, having been a customer for over a decade, but I’m always a little bit uncomfortable with your pricing. It seems excessive. I think it’s weird that you don’t fill up a bottle of capsules, but charge a high price for only 60 capsules, which don’t last more than 30 days if the recommended dosage is “take two per day.” Even worse, if the dosage is three per day, then the supply in the small bottle only lasts 20 days; for example, one product called CircuZyme. I understand the superior quality of your products, at least I trust what you claim, and that’s probably why you justify your high prices. I wish you would provide more discounts and special deals more often, to your loyal customer base.

I've been a loyal customer for over 10 years. I had an awesome experience over that time but my last order was not delivered to me. I emailed customer service and they sent me the date the delivery was made somewhere. I emailed again and did not receive a response, so I can no longer trust QNL to deliver what I pay for. I've since found an alternative for my supplements and I hope QNL improves their customer service so they won't lose long time happy customers in the future.

Hi Mike, we’re really sorry to hear this and appreciate your many years with QNL. Your order was sent to the address provided by Google Pay at checkout. Since we don’t choose that address, we recommend checking with the recipient to see if they received it. As outlined in our return policy (qnlabs.com/return-policy), we’re unable to take responsibility for third-party shipping selections. Please contact us at 800-370-3447 or info@qnlabs.com if we can help clarify anything.

Decent products but a shipping nightmare. No one can decide whether a signature is required for delivery - FedEx says no, but then won’t deliver because they say the shipper needs a signature. Not a FedEx issue when it’s happened for both shipments - both of which were delayed.

Thanks for the feedback — we’re sorry for the hassle. It looks like the address was missing a unit number, which caused FedEx to hold the delivery. While we don’t require signatures, FedEx may if the address isn’t clear. Feel free to contact us at info@qnlabs.com or 800-370-3447 so we can update your info and avoid this in the future!

Dr. Bob Marshall was an exceptional gentleman. The company he built and the products he developed are a true testament to his vision and integrity. I still use them to this day — they’re the only supplements I trust. I’m deeply grateful for his legacy and the positive impact he’s had on my health.

I placed my first order in March 2025, my second in April and will continue ordering QNL's incredible products. My first order was over the phone and Jana was the representative I talked with. She was amazing! We talked for over an hour. She explained QNL's processes and she knows so much about the body. Daily, I've been taking their Plant Multi-Vitamin, their Garlic Complex, their Kidney Support and their Organic Greens. I've used vitamins and supplements all my life, and didn't expect to notice changes with QNL's products, however, my physical improvements leave me almost speechless. My lower back pain is gone! My tinnitus has lessened! My bladder muscles have strengthened! I don't feel "draggy" any longer. I am sold, and I strongly recommend QNL's products. And something else I'm extremely impressed with is their employee rentention! Employee retention is huge! I am very grateful to my cousin for recommending QNL!!!

We have been using QNL products for years, primarily through our naturopathic Dr. The high quality of the products is obvious, and we will probably keep using them for some time to come.
