“I have been buying Quantum and Premier Research supplements for more than 20 years. I take them daily. These are the best supplements on the market and my body responds very well to most of them, especially those in liquid form. The only negative is that many of the good ones are no longer available. Over the years, several of the best supplements have been removed from stock, such as the CoQ10 in liquid drops form. More recently, I miss buying the Nutritional Yeast Flakes and Apple Cider Vinegar capsules and a few others that are no longer available. I hope Premier never stops making the liquid Max Bs, liquid B12, Gallbladder ND, Liver ND, liquid D3, Blood Sugar Support, CoQ10 caps, the excellent Vitamin C, NAC, Kelp, and all the other best supplements that keep me healthy. Thank you.”
“I’ve used your products for over 20 years and I know they are good quality. I’m saddened though that the high prices has caused me to find other avenues for most of my supplements.”
“Great, innovative supplements . Old B complex, which used live, end-chain probiotic bacteria to make Vitamin B12, was much better than the current dead Vitaimin B-Complex supplement. Is there any way that you can bring back the old B complex formulation in assimilable liquid form? It was tasted terrible, but it was far superior to the current dead B complex formation. Please do let me know your plans in this area of your company. You may contact me at 925-457-5468.
Also, QNL has moved away from whole foods and supplements to extracts. However, I will continue to be a repeat customer in particular for 25 percent off items.”
“i have been a believer in The Late Dr Robert Marshall since the late 1980s. The Quantum Brand has been the only brand i have used for a long time. From time to time there are money issues but other than that by God's permission i hope to purchasing the basic products.”
Thank you so much, Gregory. It means a great deal to know you've trusted Dr. Robert Marshall's teachings since the late 1980s and have continued choosing our products through the years. We truly appreciate your loyalty and kind words, and we pray our products continue to support you for many years to come.
“I've been a customer of QNL for years. Great products. Disappointed though that you discontinued the oil of oregano. My favorite product. Would give you 5 stars if not for that.”
Thank you for being a long-time QNL customer, Thomas! We’re glad you’ve had such a great experience with our products over the years. We also understand how disappointing it is when a favorite like our Oil of Oregano is discontinued. We appreciate your feedback and your continued support!
Thank you, Daniel! We’re glad you’ve found a strategy that works for you. Our sales are a great opportunity to stock up, and we appreciate you choosing QNL when those promotions come around!
“I love all of the products I have purchased from QNLabs. However, I am disappointed in the terrific increase in prices! I don't believe I'll be able to continue purchasing from you because of these prices!”
Thank you for your honest feedback, Susan! We’re so glad to hear you’ve loved the products, but we understand your concern about pricing. Rising costs have been challenging, and while we work hard to maintain our strict sourcing and quality standards, we know affordability matters too. We truly appreciate your support over the years and hope we’ll have the opportunity to continue serving you.
Thank you for your feedback, Cheryl. Our Memorial Day promotion was only available for a limited time, and orders placed during the sale period automatically received the discount. If you have questions about your order or would like us to take a closer look, please reach out to our team at 800-370-3447 or info@qnlabs.com. We’re always happy to help!
“I have always been so pleased with your products. However, this time, I was very disappointed in the Cayenne pepper product. It was only a little bit over half way filled. I wouldn't order that product again. I am a fan of your products and your team so it won't keep me from coming back.”
Thank you for your continued support, Beverly! We’re really glad you’ve always been pleased with our products.
For 100% Organic Cayenne Powder, the product is filled and sold by weight, not by container fill level, so some space in the bottle can be normal. That said, we understand how that can be disappointing visually, and we appreciate you sharing your feedback. We’re grateful you’re sticking with QNL and valuing the team and products!
“Placed an order on April 8th and then received an email on April 9th about a 20% off sale. I lost that 20% discount on my order. Are QN Labs specials posted the same date every month? If yes, what is that date?
I'm not happy I lost that discount.”
Thank you for reaching out, Frederick. We completely understand the frustration, timing like that is never ideal.
Our promotions are not scheduled on a fixed monthly date, so they can vary based on the offer. Because of that, we can’t guarantee a set day each month for discounts.
That said, we do understand your situation and appreciate you bringing it to our attention. If you haven’t already, our customer service team can review your order and help you further at 800-370-3447 or info@qnlabs.com.
Thank you for letting us know, and sorry the VIP discount code didn’t go through. Our support team can help get that sorted for you right away at 800-370-3447 or info@qnlabs.com. We appreciate you both and are happy to help resolve it!
“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.
“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, Sandra! We’re glad the product quality and delivery experience have both been solid for you. We appreciate you taking the time to share your feedback and choosing QNL.
Thank you for sharing this, Daniel. We’re glad you’ve had a good experience with the product overall. Our Returns team will be reaching out to gather a bit more information and review the situation, as next steps can depend on a few details. We appreciate you bringing it to our attention and choosing QNL!
Thank you, Charles. We truly appreciate the encouragement and your support. It means a lot to know our work continues to matter, even during challenging times.
“Difficulty with follow up after order challenges that got lost in their system. They were fairly nice but could have handled it with more grace and kindness. I’m a regular customer. Their products are very effective!”
Thank you for sharing this, Teresa. We appreciate your honesty and your continued support as a regular customer. We’re glad the effectiveness of the products has stood out for you, and we also hear your feedback about the follow-up experience. That kind of input is important to us as we work to improve how we handle order issues. Thank you for choosing QNL and for taking the time to let us know.
Thank you for the feedback. We’re glad you enjoy the products. Our pricing reflects the quality of our ingredients and the extensive testing behind every formula, though we understand it can feel expensive. Keeping an eye out for sales is a great way to save, and we appreciate you choosing QNL!
