First, all of you are great. You have superior products. Second, Since I'm going to be on products such as Digest, HCl and HCl Activator, PLEASE ofer them in 150 to 300 capsule sizes. You can do it with Calcium, so I wouldn't think it would be too hard to do for these digestive products. Thanks. BobD

Exceptional products! I get most of my supplements from Quantum Nutrition. Top choices include Vitamin B complex, Green Tea tincture, whey protein, and adrenal support. I like how they have a wide range of supplements and add new ones once and a while.

I have been a QNLabs customer for 23 years. Their products are of the highest quality and their customer service reps are outstanding. I would give them an A+ rating and highly recommend them to anyone, which I have done many times over the years and will continue to do so.

Love the carvacrol or now called Oil of Oregano but severely disappointed in Neem Oil no longer carried. Very bad review for that. Once loved Ozenated Gel gone and now Neem Oil. And still waiting on DHLA! WTF?!? Over YEARS AND YEARS relationship with Dr Marshall and Clive….. BREAKING MY HEART.

Hi Julie, Thank you for sharing your feedback. We truly value your loyalty and are grateful for your longstanding relationship with us. We understand your disappointment regarding the discontinuation of Neem Oil and Ozonated Gel. Your feedback is important and will be shared internally to help guide our future product innovation. Regarding DHLA, we still plan to launch this product once it meets our strict quality standards. We’ve faced challenges due to raw material shortages, but we are committed to bringing back many of our discontinued products as long as they meet our quality standards, as providing uncompromised quality remains our top priority. In fact, just this week, we had to turn down two batches of raw materials—cilantro and rosemary powder—because they did not meet our stringent requirements. We remain dedicated to using only the highest-quality ingredients in our products. In the meantime, if you would like assistance in finding alternative solutions for your health needs, our wellness consultants are available to help. You can reach them Monday through Friday, 8 am - 6 pm CST at 1-800-370-3447, or contact us at info@qnlabs.com. We appreciate your continued support and understanding.
