Top of the line. I invite you to look at their commitment to quality. Their clinical protocol page is a huge help with searching particular symptoms and finding supplement recommendations for those symptoms. They carry the right matrix formulas for any given protocol. I spent lots of time confirming this. I have no doubt they update their formulas with the latest and greatest advancements. I have no need to search for any other manufacturer. Thank you!

Douglas labs products are high quality. Two practitioners that I see have encouraged me to use this company, as they have such good quality control. Ive used the quercetin bromelain complex for many years and I can really tell the difference if I use the same supplement from another company. I recommend Douglas Labs.

Bought from them once years ago and they keep spamming me. Email, postal mail and now text messages. Trying to take yourself off their list is useless. Good companies dont spam former customers for over two years.

Pros:× Seems to work [as well as most other supplement companies products]Cons:× Poor/Lazy/Careless customer care× Received empty capsules in a bottle of product I ordered.Based on the fact that Ive had success with other companies and their equivalent products, Ill be switching to a different company from which I receive my suppliments.

Love there products, they work. The junk in Walmart and places is garb
