I trust the products. After taking my eye exam, my eye doctor blurted, "Boy, some body has been eating their Wheaties. " Your eyes have improved. I had been taking the eye supplements for about a year and a half. So I buy with confidence.

Good quality products. QNL stands out, because I know of no other supplement company who uses vegetable caps instead of gel caps in their manufacturing process.

Since you have asked for my feedback, I have said this before, so I will say it again. I am 72 years old. I will be on Digest, HCl and Activator for the rest of my life, yes? I know I it is a "Yes.". So, please make these products in larger containers. I go through a 60 capsule container of Digest very, very quickly. Please continue to offer the 60 capsule size. Please offer me a 120 to 150 size. It will save A LOT of plastic from getting into the environment!

I was a listener of Dr Marshal for more than 20 years & coincidentally ended up moving to RR, TX. I was happy to know that QNL was a local business & I actually met Dr Marshall in the parking lot of the local supermarket, by chance—amazing man in all aspects. On the other hand, the QNL pricing has become excessive & coupons are rare. Nowadays, other online retailers have the same to very similar formulas for much less. Not every supplement assimilates with every individual, but the Zinc Liquid needs to be reformulated—it’s extremely metallic in taste and reaction, I can’t tolerate it whatsoever; waste of money for me. Max Energy Bs are good, but expensive—Bs need to be taken daily, so I can’t keep up with QNL Max Energy due to pricing. Also, some of the customer service, namely via online support are not friendly. Simple inquiries are answered in unfriendly, written tones & when you ask for details, the answers are blunt and unhelpful.

Hi there, That story about meeting Dr. Marshall is something special. He had a real gift, and it’s clear he made a lasting impression. We’re really sorry the Zinc Liquid didn’t work for you and that your customer service experience didn’t feel friendly or helpful. That’s not how we want anyone to feel when reaching out. We also understand how pricing can be frustrating, especially when you’ve been with us for so long. We hear you, and we appreciate you taking the time to be honest with us. If there’s anything we can help with, feel free to reach out to our team at (800) 370-3447 or info@qnlabs.com.

Me and my family have been using QNL products for a very long time. We love them! We recommend them to friends and family. I, myself, am very grateful for them because they have helped me with a number of issues. Please keep doing what you're doing. One negative issue is your website. It is not user friendly at all. When I'm trying to add a product to my subscribe and save I can't believe the only way is to scroll through all the products page by page to find it. There should be an option to search for a product and then an option to add it to your subscribe and save.

My mother got me started here. She has been taking your products for a long time and has nothing but praise. I won't say that I was a believer at first but everytime mom would make things right when my body was feeling off, then I started to believe.

I have a question.. did I really order only ONE digest? BC that's against my nature. I go for duplicates to get discounts. I chalked up to my error. Packaging was admirable.
