You've probably heard about antioxidants numerous times‚ since they're found in many of the foods you eat—and even in red wine! However‚ did you ever think about what they actually are? An antioxidant is a substance that has the potential to protect your cells against damage from harmful atoms called free radicals. Free radicals caused by largely unavoidable exposure to environmental stressors‚ like radiation or smoke. Free radicals are also produced when your body breaks down certain foods. There may be a connection between free radical damage and health problems. If you aren't consuming an adequate amount of antioxidants in your diet‚ you may be missing out on their benefits.

Douglas Laboratories’ Quercetin-Bromelain Complex is one solution to a diet low in antioxidants. Its ingredients support the digestive process‚ while working to decrease your body’s response to allergens. The nutrients contained in Quercetin-Bromelain Complex include:


  • Quercetin‚ which is an antioxidant that promotes digestive health and positively affects immune response

  • Magnesium‚ which plays a role in over 300 biochemical reactions in your body; it’s necessary for a healthy immune system and energy metabolism.

  • Bromelain‚ an herb that may have anti-inflammatory properties‚ as well as the ability to help in the digestion of protein.

  • Vitamin C‚ which may potentially have the ability to aid in getting rid of waste products that are produced from the metabolism processes.


Each bottle of Quercetin-Bromelain Complex by Douglas Laboratories contains 100 tablets. At the recommended dosage of two to four tablets twice daily‚ you'll have a 12- to 25-day supply.

      Asthma fighter

      from Grapeview WA on 11/21/2018
      This Quecetin Bromelain Complex by Douglas Laboratories works well with other asthma supplements. It is not as expensive either. Made an appreciated difference when trying to breath during the forest fire smoke.

      Pros

      Effective and not too expensive

      Cons

      Nothing.

    • Needs more Bromelain

      from New Orleans on 11/02/2018
      I dig these double-up synergistic supplements but for those of us who take both of these supplements the Bromelain content of this one needs to be higher.

      Pros

      I like that it pairs synergistic compounds

      Cons

      I’d like to see 100-200mg of Bromelain in here

      Rice free

      from LONDONDERRY NH on 4/08/2018
      I've searched everywhere for a rice free quercetin and Quecetin Bromelain Complex by Douglas Laboratories is it! 

      Pros

      Rice free is an important issue for me. I use this for my dog as she is intolerant to rice.

      Cons

      Nothing.

      Amazing for your immune system.

      from Orangevale, CA on 6/17/2017
      I use Quecetin Bromelain Complex by Douglas Laboratories and the Allergy Group Vitamin C to help me keep my food allergies under control. Both are excellent. Can't live without them.

      Pros

      Helps control food allergy hives.

      Cons

      Nothing

      Works great for food allergies!

      from Orangevale, CA on 4/10/2016
      I have a list of food allergies that reads like a novel - really bad. I admit it; I cheat. If I take Quercetin am and pm, I can eat small amounts of my items on the avoid list. I am working on my own immunology. Quercetin Bromelain Complex by Douglas Laboratories bolsters my immune system and reduces inflammation. Much better than prescription alternatives.

      Pros

      Helps reduce my hives from food allergies.

      Cons

      Nothing, but I would double check for interactions with prescription drugs for sure.

      Allergies Conquered!

      from Houston, Texas on 2/01/2016
      After years of allergy antigen injections and using 2 different allergy Rx daily, including an expensive eye drop, I began taking Quercetin Bromelain Complex by Douglas Laboratories on the recommendation of the owner of a health food store, who is a former nurse. I was able to stop all the allergy meds and have had NO allergy problems or sinus infections at all. (Note: I also was in the process of changing my diet to detox and also to achieve a healthy gut. I'm assuming the combo of that and the Quercetin/Bromelain produced the great result.) After 2 years, it's still working wonderfully well, even when Mountain Cedar pollen is in the air!

      Pros

      I'm not putting chemicals with harmful side effects into my body, but rather enabling my own immune system to work even better. And I'm saving a lot of money by not paying $150 out-of-pocket for the Rx allergy eye drops every month.

      Cons

      Not a thing.

      Exceptional Product

      from Greenville, SC on 4/19/2014
      This product was recommended to me by my doctor for bruising approximately 3 years ago. At the time I was skeptical as nothing had worked in the past for bruising. However after I started taking Bromelain I stopped bruising by about 99%. Two years ago I had a facelift surgery schedule and a month prior to the surgery I increased the amount of bromelain I was taking daily. When my surgery was complete I had no major bruising only a small stain of a light bruise on one cheek. I was able to go out in public for dinner within a couple of days. I have had exceptional results with Douglas Labs Quercetin Bromelain Compllex and highly recommend it to others.
