    Description

    Description

    Nature's Lab Quercetin Bromelain contains two powerful plant botanical ingredients with a variety of health benefits including enhanced immune function and antioxidant support.*

    Quercetin is a type of flavonoid, a natural compound that serves as a plant pigment. It is found in the skin of vegetables, flowers and fruits and is a potent antioxidant that helps protect cells from oxidative stress caused by free radicals.* Bioflavonoids are a group of compounds found in foods with high sources of vitamin C.* 

    Bromelain is an enzyme complex derived from pineapple (Ananas comosus). Bromelain’s enzymatic role can help induce the body’s natural reaction to fight oxidation and free radicals.* Studies have shown that bromelain enzymes promote healthy cell regeneration and wound healing.* 

    Quercetin is taken as a dietary supplement for its potential benefits ranging from boosting immunity to providing allergy relief.* Bromelain supplements are noted for potential benefits in improving digestion and immune responses. The combination of quercetin and bromelain can inhibit the activation of mast cells, immune cells containing chemicals like histamine, heparin, and more.* 

    Key Benefits

    • Supports immune system health*
    • Enhance response to free radicals*
    • Promotes cell health and regeneration*
    • May combat neuroinflammation* 
    • Can stabilize mast cells to help allergy symptoms.*

    Benefits of Quercetin

    This naturally occurring plant flavanol acts as an antioxidant that boosts immunity and deters oxidative damage from free radicals in the body.* Quercetin is a lipophilic molecule, meaning it can easily cross the blood-brain barrier, making it beneficial in combating cognitive decline.* Aside from its antioxidant properties, quercetin also has virus fighting properties that may inhibit the ability of viral replication and aid immune response.* The safe dose of quercetin supplements is up to 1000/mg per day (source: NIH).

    Benefits of Bromelain

    It has beneficial digestive properties that aid in the absorption of nutrients and the breakdown of complex proteins in the gut and is recognized for its inflammation fighting properties, especially against inflammation caused by infection and injuries.

      Suggested Use

      As a dietary supplement, take 2 capsules one time daily, preferably with a meal, or as directed by a qualified healthcare practitioner.

      Warnings: Pregnant or lactating women and people with known medical conditions and/or taking drugs should consult with a qualified healthcare provider prior to taking dietary supplements. Discontinue use and consult your doctor if any side effects or allergic reactions occur.

      Quercetin may interact with certain anticoagulants (blood thinners) and antibiotics. Ask your doctor about potential interactions with medications before introducing it to your regimen.

      FAQs

      Why is quercetin combined with bromelain?

      Bromelain may increase the absorption of quercetin in the body, making it more effective. It also contributes additional inflammation-fighting and swelling-reduction properties to the supplement.

      Can I take quercetin and zinc together?

      Yes, you can take quercetin and zinc together. Both are natural supplements with immune-boosting properties, so it can be beneficial. Be mindful of dosages and consult your healthcare provider if you are taking other medications or have underlying health conditions.

      How should quercetin with bromelain be taken for best results?

      Supplements should be taken to complement an already healthy lifestyle. It's recommended to take it on an empty stomach to maximize absorption, but following the specific dosage instructions on the product label or those provided by a healthcare provider is important.

      We Build Around What Works

      "Most supplement brands begin with a budget and formulate around it. We take the opposite approach - starting with the research. We look at which forms offer the best bioavailability, which doses are supported by clinical studies, and what the evidence truly shows. Every ingredient in a Nature’s Lab formula earns its place. If clinical research doesn’t demonstrate real benefits at the dose we use, it doesn’t make it into the bottle."

      Customers praise this supplement for immune support, allergies, and inflammation. Many noted it "helps a lot with allergies" and supports digestion. However, concerns exist about quality control—one customer reported a "very fishy odor and taste," another received "leaking capsules." Some prefer cleaner ingredients without additives.

      I got three immunity supplements

      I got three immunity supplements to give my body a super boost of protection. This is my first time taking Quercetin Bromelin and I think it works well. I took it when I was sick and I think the trio helped speed my recovery. * I also took a type of Vitamin C and an immunity boost.

      Very fishy smell and taste

      This bottle of Quercetin Bromelain has a very fishy odor and taste on the tongue, really awful! I've ordered these in the past, but they weren't like this. I don't feel safe taking them, something is definitely wrong with them.

      I deal with a lot

      I deal with a lot of allergies and sinus issues especially around cold and flu season as this product has really helped to boost my immune system. I've hardly gotten sick since I've added these supplements to my routine and it's also helped reduce the amount of headaches I get. Definitely recommend!

      I hope it works. Too soon to tell

      I�m taking it to support my immune health. It will take time to notice if it actually has benefited me. It�s not a product that has immediate noticeable benefit. I�m hoping.

      Has worked for my wife

      I got this for my wife for her itching, she has an auto immune issue with her hands and eating certain foods. So she cannot eat gluten or dairy and this helps her hands to not burn as much and heal faster. It seems to lessen the blow for her eating foods she can't eat now that this condition has developed.

      Great Combo but comes with Additives

      Quercetin + Bromelain is a great combo. Quercetin is a natural anti-oxidant and anti-inflammatory while Bromelain is also an anti-inflammatory and analgesic which also helps increase the absorption rate of Quercetin. This combo is great for immune support and also for allergies.

      The recommended serving size is two (2) capsules daily after a meal. The capsules are regular-sized and are easy to swallow. It is flavorless and does not have any aftertaste.

      I dislike that these have Magnesium Stearate and Silicon Dioxide added. Supplements should start rolling out pure substances without any additives. Overall, great supplement and good value. Wish they update this product without any additives.

      Good Concentration & Price

      I've been using quercetin with bromelain for sinus/allergy issues for years with great results. This particular one has a slightly higher dose of 800 mg vs. the usual 500 mg for two capsules. It has performed just as well as other brands I've tried. You also get a two month supply for under $20 which is a pretty good deal. The Nature's Lab brand is pretty popular and sells many different supplements. They are based out of Nevada but do not state on the label where the ingredients sourced.

      A great combination of substances with benefits

      I don't know which I like better -- the Quercetin or the Bromelain. It's good I don't have to choose with this product.

      It's interesting that this product is marketed as "Quercetin with Bromelain". I was looking for a product with Bromelain for it's benefits, and found this. It reminds me to the commercials -- "You got chocolate in my peanut butter... You got peanut butter on my chocolate".

      Good dose and easy to use

      I've been taking quercetin and bromelain since 2020 and I don't know if it's coincidence, but my allergies are all better. I like that this combination has only two ingredients because I don't have to compute/calculate overlapping ingredients like other supplements have [in order not to overdose on anything].

      Easy to swallow. Good basic dose. 30c per dose [as of this review]. Great value.

      GOOD FOR INFLAMMATION AND ALLERGIES NON GMO VERIFIED

      I use this as a natural alternative to over the counter anti-histamines. Research reports that quercetin can have anti-allergic and antihistamine properties. Quercetin has antioxidant and anti-inflammatory effects that might help reduce swelling, kill cancer cells, control blood sugar, and help prevent heart disease. For all the healthy protection this offers, I make sure I have this in my health cubbie.

      Very Good Supplement

      I think this product has the correct ingredients to keep one's immune system in top working order. Quercetin is extremely good at getting zinc into the cells. This supplement contains bromelain which might help with eye floaters as a study in Thailand suggests. I think this is an excellent supplement.

      Very good combination Quercetin and Bromelain supplement.

      Separately quercetin and bromeliad are highly regarded for their antioxidant and anti-inflammatory characteristics. Together, they are synergistic, enhancing their health benefits regarding immune systems and cellular health management/maintenance.
      The product details touts the company�s measures to ensure the quality and integrity of the supplement. Aspects including Manufactured in the USA and USP Audited to meet GMP standards and abiding by FDA regulations. The product label displays none of these certifications/badges (it does state that it is manufactured in USA with US and imported components). I would have a higher regard for the product if the label contained USP Audited, cGMP and FDA badges.
      Per capsule, it supplies 800mg Quecetin Dihydrate and 100mg Bromelain (2400 GDU/g). While the suggested serving size is 2 capsules, if you are just starting to take this supplement, to begin with one capsule/daily. Then gauge any sensitivity, and increase to 2 capsules after a week of observations.

      Quality supplement

      This is a good quercetin supplement, which I've been taking for years for immune support. Easy to swallow capsules, no odor. Simple formula. Good value.
