I’ve been taking QNL products for years. Dr Marshall was the first person I heard who said “we needed more stomach acid, not less” and that began my journey with nutritional products that really work. Just a few of my first favorites were Cleanse Blend and Nucleotides, not to mention Hcl and Hcl activator, the staples. I also listen to the old radio tapes for advice. I hope this company continues Dr Marshall’s code of excellence.

Thank you, Holly. It means so much to hear from longtime customers who were inspired by Dr. Marshall’s teachings. His message around stomach acid and whole-body health changed lives, and we’re honored to continue his legacy with products that meet the same high standard. We appreciate you being part of the QNL family.

Excellent products but a bit pricey even with a discount. It's too bad I have to order at least $100. to get free shipping. I would order more items from Quantum if this wasn't the case. Why is there not vitamin A in your vision eye formula.....otherwise it looks like a great supplement!

Thanks for your thoughtful question, John. While our Quantum Eye Support doesn’t list vitamin A on the label, it does contain key phytonutrients that help support the integrity and bioactivity of the vitamin A already present in the fruits and vegetables you eat. We appreciate your support and attention to detail. Thanks for being part of the QNL family!

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.
