QN Labs has provided me with several top-quality products. The digestive enzymes and HCL are essential for good results with cooked foods. I really appreciate the information available from QNL. TJN

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!

Greetings to all: I continue to buy from QNL because I trust your integrity and quality of supplements. It's all because of Dr. Bob Marshall (His memory is for us a blessing; may he be at peace). I used to listen to him on the radio, some years ago, and found his discoveries and recommendations fascinating. What a loss it was to learn of his passing. Please continue to offer products of such high quality. Thank you. S.J.

I have been using quantum for about 5 years. I still have not received my order! It's been 2 weeks for the 2 day FedEx...still nothing. I've reached out several times and have asked to speak with a real person, she did nothing but sent me a receipt. Asked to speak with a pharmacist - apparently you don't have one. I have requested refund now 3 times with no response.

I love your products and have used them for decades. I used to call to order them but in the past two years have been able to order them online. For the last several months your website has become quite unfriendly. I put the products in my cart but then am unable to check out. it has been quite frustrating. I am hoping that things will change soon so it will be easier to order online again.

I have been purchasing supplements from QNL for about 10 years. I have found their products to be of great quality. The orders are processed quickly & delivery is quick too. Packages always arrive in great shape with never any breakage of the glass items.
