9 Best Quercetin and Bromelain Supplements: Benefits and Reviews 2023
What Is Quercetin?
Quercetin is an antioxidant that belongs to a class of water-soluble plant
substances called flavonoids, which are present in certain fruits and
vegetables. According to
an article
in Current Research in Nutrition and Food Science, the bioavailability of
quercetin absorbed by your body varies, depending on the source where you get
it, as well as your individual body’s metabolism of it. Sugar and dietary fat
and fiber also affect it.
While the best way to get quercetin is through your diet, it also is available in supplement form, as pills or capsules. Sometimes, quercetin in supplement form is packaged with bromelain, an enzyme found in pineapples, because both have anti-inflammatory properties (Quercetin & Bromelain for inflammation). Most dietary supplements contain a chemical compound, aglycone, which is the free form of quercetin.
When looking for and using quercetin supplements, it’s important to maintain a nutritious, balanced diet with fiber and healthy fats in it, as research shows that accumulation of quercetin in the body is dependent on “factors such as glucose moieties, solubility, human factor, vitamin C status and food matrix.”
Specifically, research also says that quercetin supplementation is best achieved when consumed with a fat-enriched diet.
There are foods high in quercetin that you can add to your diet. Arguably, red onions are some of the most potent sources of quercetin; one study found that absorption of onion-derived quercetin was 52% compared to only 24% in supplement form. In fact, onions can give you three times the amount of quercetin than you’d get from apples. Other food sources that are high in quercetin include:
- Organically grown apples, grapes and tomatoes
- Dark cherries and dark berries like blueberries, blackberries and bilberries (eaten in moderation)
- Cocoa, unsweetened
- Hot green chili peppers
- Lingonberries
Benefits of Quercetin
Quercetin has been linked to the following health benefits:- Possessing anti-inflammatory, antioxidant properties that can help combat certain diseases. One study found that 500 mg of quercetin a day could improve symptoms of rheumatoid arthritis.
- Helping prevent cancer cell growth from breast, colon, prostate, endometrial and lung.
- Counteracting allergic reactions and helping with immune responses.
- Helping to prevent osteoporosis
- Addressing cognitive decline, including Alzheimer’s and dementia.
- Assisting in control of blood pressure. A study in 2002 found that quercetin can have vasodilator effects.
- Potentially helping to lower blood sugar levels. One study found that dosages of 500 mg per day “significantly reduced” fasting glucose levels.

What is Bromelain?
Bromelain, or pineapple extract, is a compound made up of proteases normally found in pineapples. Although it is widely known for its ability to aid in digestion and protein breakdown, its use far transcends these functions and can actually offer a lot more. The good news is that it's available in the market as a supplement and as an aid for disease treatments.The history of bromelain is heavily linked to pineapple because it is the only known major source for this group of enzymes. First discovered in 1891 by chemist Vicente Marcano and then subsequently elaborated by Russell Henry Chittenden, another chemist, bromelain was first called "bromelin," and described as the "proteolytic ferment of pineapple juice."
Its first primary source was the pineapple fruit, before it was discovered that the mature pineapple stem had much more concentrated bromelain content.
Through the years after its discovery, the production of bromelain has broadened. Its commercialization has led manufacturers into developing faster extraction techniques for large-scale production and purification. Today, bromelain supplements are used for numerous health approaches.
These uses have been observed to be dependent on the time when it is taken. For example, if taken after a meal, bromelain may help promote better digestion and absorption, but when taken on an empty stomach, it can help alleviate inflammation.(Daily Mail)
Benefits of Bromelain
As a protease enzyme, the primary benefit bromelain has is improving protein absorption. However, bromelain has been widely used to promote healing and assist in the treatment of numerous diseases. For example, if you're suffering from chronic inflammation or from sports injuries, consider taking bromelain supplements to help your body recover. Other bromelain benefits that you'll get from this supplement include:• Reduces inflammation and swelling — Bromelain may help alleviate symptoms of osteoarthritis and rheumatism. It's also used to help in sprain and strain recovery by reducing swelling and promote tissue healing. For people who are currently on arthritis medications, consider switching to bromelain for a more natural alternative.
• Improves immune function — Studies show that bromelain promotes a healthy immune system by regulating numerous inflammatory proteins during periods of cellular stress.
• Speeds up wound healing — The use of bromelain post-surgery has been observed to promote soft-tissue healing and reduce bruising. Patients who took bromelain also had shorter wound healing time compared to patients who did not.
• Relieves sinusitis symptoms — Sinusitis refers to the inflammation of the inner lining of the sinuses, which is usually caused by infections, nasal problems or allergies. Bromelain is a known supplement for relieving sinusitis symptoms. Together with quercetin, bromelain can help alleviate sinus inflammation, with quercetin functioning as an antihistamine.
• Promotes blood flow — Bromelain helps in promoting healthy blood flow by reducing platelet aggregation in the arteries and lowering the chances of clots forming. This may lower your risk of developing atherosclerosis and other cardiovascular diseases.
There are also claims that bromelain can help induce menstruation by softening the uterine lining. The increased blood flow also supposedly helps in the prevention of menstrual cramps.
Because of the impressive components of bromelain, it's not surprising that it's been utilized in treating or reducing the severity of disease symptoms. While it is usually prescribed or recommended for patients who have undergone surgery or people suffering from chronic sinusitis, bromelain can also be used in other ways. These include:
• Topical application for burns — Studies suggest that bromelain can help remove dead skin cells from third degree burns and assist in burn healing in first and second degree burns. For severe burns, do not apply any bromelain ointment without a physician's supervision.
• Indigestion and heartburn — Taking bromelain has been known to assist in easing indigestion and bloating, especially when taken with other supplemental enzymes.
• Soothing balm for insect bites and stings — Applying bromelain directly to insect bites and stings may lessen inflammation and discomfort.
• Meat tenderizer — Pineapple has been used in cooking to soften meats. Today, bromelain is sold in powder form as a meat tenderizer and is usually combined with papain, an enzyme found in the papaya plant. In fact, bromelain is such a strong meat tenderizer that chefs and cooks claim it can turn meat into mush if left marinated for longer periods of time.
Quercetin with Bromelain for Inflammation
Studies have shown that systemic enzymes for inflammation (like bromelain) combined with quercetin, produce greater anti-inflammatory benefits than either one used alone. Thus, the combination of bromelain and quercetin is ideal for effectively inhibiting the inflammatory response in both acute and chronic inflammatory conditions.Since bromelain and quercetin are recommended to be taken together for maximum anti-inflammatory benefit, formulas that contain both ingredients are ideal. This also simplifies the dosing schedule and reduces the total number of capsules needed to be taken throughout the day.
Quercetin with Bromelain for Allergies
According to this
review article, quercetin is known for its antioxidant activity and anti-allergic
properties.
A study (2013)
that was done on people with chronic rhinosinusitis (inflammation in the
sinuses) indicated good tolerability, symptom control, and improvement in QoL
(quality of life) for the treatment of CRS (chronic rhinosinusitis) using
bromelain tablets.
On top of improving absorption, bromelain together with quercetin, can help
alleviate sinus inflammation, with quercetin functioning as an
anti-inflammatory.
Quercetin with Bromelain for Hives
Hives, also known as urticaria, are itchy, generalised, raised red
discolouration that are found on the skin. They are usually red, pink, or
flesh-colored, and sometimes they sting or hurt. In most cases, hives are
caused by an allergic reaction to a medication or food or a reaction to an
irritant in the environment.
In many cases, hives are an acute (temporary) problem that may be alleviated with allergy medications. Most rashes go away on their own. As with any allergic reaction, if hives are accompanied by difficulty breathing or swallowing, this can be a sign of a much more severe and serious anaphylactic reaction. This requires immediate emergency medical attention to treat. Please see your doctor and go to the nearest 24 hr emergency clinic or hospital immediately.
Dr Deborah Gordon recommends trying a food elimination diet to pinpoint the source of the problem. Thus, if you get rid of the source, you won’t have to worry about treating the hives.
Antihistamine drugs also stop the release of the histamines that cause the hives in an allergic reaction. However, people who suffer from chronic hives don’t usually want to take medication for months or years if they don’t have to.
For this reason, some allergy sufferers turn to natural alternatives such as quercetin; that works by stabilizing the membranes of cells that release histamine. This often helps brings inflammatory and allergic reactions under control. You can buy quercetin products in natural foods stores or Amazon. The best form is a coated 400 mg tablet, taken twice a day between meals; as recommended by Dr Andrew Weil. It can take six to eight weeks of continuous use for quercetin to build up to therapeutic levels in the body.
As mentioned above, bromelain can help to improve the absorption of quercetin
to provide greater benefit when taken together.
Quercetin with Bromelain for Sinusitis
Categorically, there are two types of sinusitis:
Acute sinusitis - an infection that is often triggered by the flu or cold. The flu or cold virus attacks your sinuses causing them to swell and become narrow. Your body responds by producing mucus. When the sinuses become blocked and are filled with mucus, viruses, fungi or bacteria can grow and cause infections that cause pressure and headache.
Chronic sinusitis - an infection that lasts for more than 3 weeks and can continue indefinitely if not treated. It is often caused by allergies, fungal infections or weakened immune system.

Chronic sinusitis - an infection that lasts for more than 3 weeks and can continue indefinitely if not treated. It is often caused by allergies, fungal infections or weakened immune system.
For those with chronic or recurring sinusitis, you could consider rinsing
your sinuses once or twice a day with a nasal saline solution.
Bromelain helps support the sinuses because of its powerful
anti-inflammatory and mucus thinning properties. A
2016 review of studies
suggests that bromelain may reduce the duration of sinusitis symptoms in
children, improve breathing, and reduce nasal inflammation.
Quercetin has amazing anti-inflammatory and anti-oxidant effects. Since bromelain and quercetin are recommended to be taken together for maximum anti-inflammatory benefit, formulas that contain both ingredients are ideal.
Quercetin with Bromelain for Weight Loss
However, there have been mixed reviews and conclusions on the effects of
quercetin for weight loss and its effect on the expression of certain
genes.
These inconsistent findings from the studies maybe are due to the difference in the range of fitness of the subjects, differences in research design, different methods in the preparation of quercetin extract, etc. In order to assist you in doing your own research, let's dive into some relevant studies and reviews.

Matthew Solan, author of Doctor’s Detox Diet reports that quercetin can mimic the effect
of calorie restriction. However, it shows to have a greater effect on weight
loss when combined with other fat-fighting phytochemicals such as
resveratrol
and
genistein.
Another interesting side effect of quercetin, as reported by
MuscularDevelopment.com, is that quercetin may offer some of the same psychostimulant properties of
caffeine.
Therefore, consuming it may help people increase their activity throughout the day and delay fatigue. Plus, this can lead to expending more energy during workouts, thus burning more calories.
Dr Josh Axe also adds that some athletic supplements contain quercetin because some people believe that is increases endurance and athletic performance.

Dr Josh Axe also adds that some athletic supplements contain quercetin because some people believe that is increases endurance and athletic performance.
It was also discovered that consumption of 500 mg of quercetin twice a day increased the VO2 max (the maximum amount of oxygen that is utilised by an individual) in untrained individuals as a result of an increase in mitochondrial biogenesis.
This enhancement in fitness without exercise training can be used in disease prevention such as obesity.
In two animal studies, supplementation with quercetin
brought
about a
significant
reduction in obesity related gene expression.
Since bromelain can help to improve the absorption of quercetin, there
should be greater benefit when quercetin and bromelain are taken together.
Inflammation vs allergies vs hives vs sinusitis?
Confused? In general, there are two types of allergies; generalised and
local. Hives are generalised allergies, could be triggered by food (e.g.
peanuts) or antibiotics or certain medications. Local allergies instead
affect a certain area of the body e.g. scalp (allergic to hair dye) or face
(allergic to certain make-up).
Allergies are triggered by allergens (an allergen is normally a foreign substance that can cause an allergic reaction) leading to inflammation. However, inflammation can also be triggered not only by allergens but also by bacterial or viral infections.
For example an acne is a skin infection with inflammation. Inflammation
associated with an infection is not considered an allergy. Therefore, the
treatment approach is different.
Sinusitis basically means inflammation of the nasal sinuses (refer to the
figure above). It could be related to an allergy or infection.
Quercetin and Bromelain Side Effects
According to WebMD, quercetin is POSSIBLY SAFE for most people when taken by mouth on a short-term basis. Quercetin has been safely used in amounts up to 500 mg twice daily for 12 weeks. It is not known if long-term use or higher doses are safe.When taken by mouth, quercetin could cause headache, stomach upset and tingling of the arms and legs. Very high doses might cause kidney damage.
Those who are taking blood thinners or have concern about the adverse effects of bromelain, should consider quercetin supplements that do not contain bromelain.
Quercetin intake should be avoided by pregnant and lactating women. People
with kidney problems should also avoid its consumption.
Very high doses of quercetin (above 1 g), were found to have adverse effects on kidney functioning.

I have year round allergies and lately what I had been taking wasn't
working and my eyes were always running. It was extremely annoying and
frustrating to be crying from one eye all day. I read the reviews and
decided to try this. I've been taking them twice a day since March 1st
and I stopped crying the first day. I love these natural pills. They
work!!!!

I have histamine intolerance and had spent many years taking prescription and OTC drugs. I wanted to get away from drugs and my functional medicine doctor recommended d-hist. It worked on my allergies but I would get migraines if I took it too often. I think it was the nettles. Anyway, I also didn't like that they used magnesium stearate. I bought this and it works just as well as my Claritin did. I get relief from runny nose and sneezing as well as itchy skin. I will sometimes add some extra bromelain but I am very happy. Thorne products are often more expensive but they use better ingredients and omit questionable ingredients that make production cheaper.Our Take: If you are looking to buy from a reputable brand, this would be your choice.

Review: This is the best quercetin I found on the market! It was a
revelation to me to discover that regular quercetin is difficult
for the body to absorb. After doing my research I discovered that
quercetin phytosome has much greater absorption and is therefore
more effective. I have been taking this for over a month and my
allergy symptoms have been reduced tremendously. In addition, this
company added specific Whole Foods that contain the highest amount
of added quercetin for additional quercetin benefits. Besides
allergies I also take this for it’s high anti oxidants and many
other health benefits. I love this brand and I will continue to
buy their products.

"I’ve been on quercetin for a long time for bad allergies - the kind that requires MULTIPLE antihistamines. (Mast Cell Activation Disorder - basically your body releases too much histamine to too many stimulus). This quercetin is WAY more potent and WAY more effective than regular quercetin. I take a lot less of this, and only once a day, and it really helps my allergies. It’s a little spendy but well worth it due to it’s effectiveness. Also this is a good brand that I trust. I’ve been researching and taking supplements for more than 20 years, and this one brand I always feel comfortable recommending to others."

I started taking this when I began feeling like
a cold was coming on. My throat was really
bothering me, I had a bad headache, and I was
sneezing. Quite honestly, I thought it was
something worse than I cold but I remained
optimistic. I took the Quercetin immediately and
I felt better in a couple days. From my
experience, it seemed to prevent my symptoms
from worsening. My back also feels a little
better. I sit a lot so this supplement might be
helping with the discomfort I normally have.
