Delivered ordered product in very good time and was in good condition. Have used QNL products since listening to Dr Bob Marshall Phd and since I trusted him, I trust his products.

I appreciate being able to purchase supplements that are pure (without fillers, etc.) and also the excellent customer service that I receive from QNL.

Supplements are great. Delivery through FedEx is awful. No one contacted me on the status of my delivery and when I called QNL the representative searched the records and found that FedEx said they attempted delivery twice, was refused and they are sending it back to you. I will be purchasing the supplements from a brick-and-mortar store from now on and never again online. FedEx is awful.

Thank you for sharing your experience. We’re glad to hear you’ve been happy with the supplements, but we understand how frustrating the delivery situation was. While shipping is handled by FedEx once the package leaves our facility, we know that doesn’t make the experience any less disappointing. We appreciate your feedback and are sorry this order didn’t go as smoothly as it should have.

I discovered these products fro the radio show with Dr. Bob Marshall. These products are very very good. If one prefers to take vitamins rather than alot of medicine, this brand will work. Thank you for manufacturing a great product.

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!

Your products are wonderful. They actually work, and do what they say they are going to do. Although they are pricey. But the ongoing out of stock issue is a real problem. Can we work on this?

Thank you for the thoughtful feedback. We’re really glad to hear the products are working well for you and meeting expectations. We understand your concern about pricing and the frustration with items going out of stock. Stock issues can happen due to strict sourcing standards and production timelines, but we do hear you and are actively working to improve consistency. We appreciate your support of QNL and you taking the time to share this.
