“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.”

“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.”

“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.”

“I rate the products and the customer service from QNL a solid five stars. The only reason I am rating the company four stars at this time is because they recently changed the way that quantity discounts are calculated. Specifically, in order to routinely get the best quantity discount, customers now need to order nine bottles of a product. Therefore, it behooves customers to save money by trying to schedule their buying around holiday sales and the annual July sale - and we remain extremely grateful for these product sales-but it is now more of a challenge for the customers to get the best value for their money.”
