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.

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.

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!

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.

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!
