“Your Kidney and Prostate Support pills have gotten expensive, almost double in price. I have been taking 2 a day of each for many years but now can only offord to take one a day. I also realized that both pills have shrunk in size in the last year or so. Smaller pills, more expensive, not a good combination for continued purchases.”

“I threw away a whole bottle of the Quantun HCL that I bought from Amazon, thinking it was bad due to the smell coming from the bottle only to learn that the new bottle coming directly from the maker smells the same!”

“I love the quality of QNL’s supplements but they are becoming very expensive. Without a sale, I can’t afford to buy their supplements. Unfortunately I’m researching and seeking quality supplements from other vendors as a replacement as prices continue to rise at QNL.”

“I have used QNL products for many years and appreciate the quality and the research! What can be problematic is placing a big dollar order only to get an email the next day that the same product is now 30% off. This is a huge disappontment and financially significant as the QNL products are pricey to begin with. Other companies seem to have more predictable sales and the timing of ordering is much easier.”

Thank you for your thoughtful feedback, Marsha! We’re so glad you’ve trusted QNL for many years and appreciate the quality and research behind our products. We also understand how disappointing it can be to place an order just before a promotion begins, especially on a larger purchase. Our sales aren’t scheduled on a fixed calendar, so the timing can vary. We truly appreciate you sharing your perspective, and your feedback is valuable as we continue to improve the customer experience.

“You say you want to continue top-quality supplements, but instead you discontinue them, the latest one being chlorella. Now I have to go elsewhere to get it and give my business to them.”

Thank you for your feedback, Mary Ann. We understand how disappointing it is when a product you rely on is discontinued. While we always strive to maintain a broad selection of high-quality supplements, sometimes sourcing, demand, or other factors make it necessary to retire certain products. We appreciate your long-time support and understand your frustration regarding Chlorella.

“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”

“I recently have to use twice as many capsules to achieve the same results. I think the company was purchased and the cost cutting efforts have lowered the effectiveness of your supplements. I am searching for alternative sources.”

Thank you for your feedback, Chas. We’re sorry to hear you’re not getting the same experience. QNL hasn’t been purchased, and our formulas and quality standards have not changed. We’re still fully committed to the same purity and testing that Dr. Marshall put in place. We appreciate you choosing QNL!

“I've been enjoying some of your products over the years. It's hard to know the effectiveness of the ones that just arrived, especially because I take them along with a number of other supplements. The reason I chose 3 stars is (1) I find your prices outrageous (I purchase most of my supplements elsewhere), and (2) your website is impossible to use, especially when it comes to checking out. This problem has persisted over the course of years and I remember speaking with your customer service about it in the past. Is there a reason why it can't be fixed??”

“Product is good, but your prices have shot up wayyy too high!! Even on sale, I'm thinking twice about ordering again from you.”

We appreciate your honest feedback. We know price increases are frustrating. The reality is that our strict standards mean rejecting many raw materials that don’t meet our criteria, which does raise costs. What never changes is our commitment to purity and quality. Thanks for choosing QNL and trusting us with your wellness.

“TOO EXPENSIVE!”
Helpful Report
Posted 1 year ago
Thanks for your feedback, Thomas. While we may not be the lowest-priced option, our priority is quality. We go the extra mile in testing every single batch and lot to make sure you get a product that’s clean from pesticides, heavy metals, mold toxins, and anything else that doesn’t belong. This comes at a trade-off most companies aren’t willing to make. That’s a standard we’ll never compromise on.
