Quantum is awesome I’ve been using your products for more than five years. I have told a lot of people about your products I take them every day and I just started my daughter who is 25 on some of your products. God bless you.

I have purchased items from QNL for the past 5 or more years and have always been pleased; however, I have noticed a decrease in availability of items and service in the past 2 years. I hope this improves because I've come to depend on QNL. I'm not too pleased with the 'fermented' items....they seem to spoil quickly. I would have given this 5 stars except for the last couple of times I have tried to purchase some items and they are not available (e.g., gallbladder PG, heart PG, limonene, et al.) I wish more would be more readily available on Amazon. I miss Bob Marshall.

I love the HCL product. It really does relieve my digestive problems. QNL is a trusted company with great products.

I called and asked for your "nutritionist" to give me a list of everything I needed to be a healthy 83-year old, and she said she would. I haven't heard a word from her, but I did order product because I believe in Quantum Labs.

Nucleotide is a product I’ve used after two major surgeries. I gave a bottle to my friend after surgery and he had quicker healing while taking it as well and I ordered two additional bottles for him. Great product

I love the products as they do not bother my stomach and the quality is better than over the counter vitamins & supplements.

Have been using Qn Labs products for many years now. I have used other brands before that and QNL products are much better.

After using Dr Bob Marshall's supplements for 20 years now, I can say they are the most effective and highest quality vitamins I have ever experienced. My life is always on the go and I engage in hard work everyday an physical labor constantly. At 45 years old I haven't slowed down at all an feel better than when I was half my age.

QN products, as always, are superb. I've experienced immediate positive results with the Mg and C. Thank you! Family members love your products as well. I must add, the delivery system you use, FedEx, is deplorable. They never notified me when my order was delivered at the pick-up store. I had to track down my package myself. Even USPS has been better than that. Please switch back to USPS.

I placed my order early Thursday (the 28th/ of November),and received it on Saturday of the same week! Fantastic service! The only disappointment was that their Black Friday sale was supposed to extend to the 30th/ of November and according to my invoice, it wasn’t.

I have been ordering nutritional supplements from QNL for several years because I trust QNL. The products I have used do what they were formulated to do and give my body the nutrition it needs to stay healthy. Additionally, there are no added fillers and the supplements are derived from plants.
