I have been using the QNL Kidney Support for 6 years now and have liked how it has helped keep my CKD in check, but after the last two rounds of price increases I am going to do some research to find something similar. As far as I am concerned the product pricing has now gone from overpriced to abusive.

We hear you, Randall, and we get it. Sourcing truly clean, high-quality ingredients has only gotten harder, and we reject more than we accept to meet our standards. That commitment to quality does affect the final cost, but we believe it’s what sets our products apart. Thank you for being with us these past 6 years.

Great Products! i been loyal to since 1988 when I first heard Dr Marshall on KKLA 99.5 discussing health issues. I made an appointment soon afterward ( office on sawtelle south of the VA) and been a SUPPORTER and Customer for a long time. If i could afford it i would stock up with years of inventory of the products. Dr Marshell left a VERY VALUABLE Legacy and Thank Mrs Marshall and the Marshall Family for carrying on an Urgent medical NEED for Americans Nationwide.

We've been buying products from QNL for at least 22 years now and have never been disappointed. Their quality is top notch. None better. This is the way all companies should be.

Best heaith supplements ever. Love that Quantum ferments most of their supplements to make them more bio-availaiable. They use quality products, because I always notice a change for the better in my overall health.

Thanks for the thoughtful review, Wayne. Our founder, Dr. Bob Marshall, always prioritized bioavailability because he knew how much more effective supplements could be with the right delivery. Glad you’re feeling the results!

I've been taking there products for years and none of there products had any side effects and helped me get off of my Lexapro and another medicine for an inner ear problem. The most important for me are the digestive enzymes and the HCL Max stress B now called Max Energy B. The Adrenal Support was so great and that the Max B is what made it possible to get off of Lexapro. I did see there practitioner where they did the muscle test.. This was over 20 years ago.

My family has been using QNL products for a long time. Love them! My son who is 25 now has been taking them since he was a child. I'm not really happy with the changes recently to the VIP Program, but my family's health and well being are worth the extra cost. Your website is a complete disaster. I have mentioned this before when asked for a review. It is not customer friendly at all. There are too many steps to take when adding or deleting products from the subscribe and save.

Out of all supplements and things that can actually help you with your health, there is more research and knowledge behind these products than anything else I found

Love their products and excellent shipping. I receive my order within days, it's always well packed . I order product for my autistic brother also, and his order comes in quickly. The only problem I had was when I placed a big order when all products were on sale but they were out of max energy Bs. It was back in stock a few days later. I called to see if they would ship it for free, but they wouldn't. Other than that, nothing major.
