INGREDIENTS & FURTHER INFORMATION

CONCENTRATION OF QUERCETIN

There are no fillers of any kind present in this solution. It is notably soluble in oils (olive, coconut, etc.), and does not mix easily into water. It has no discernible flavor and should be stored in an area that is free from light, heat and moisture in order to preserve potency.

QUERCETIN SIDE EFFECTS

As long as suggested serving sizes are adhered to, it is unlikely that Quercetin will result in any negative side effects. Those who use Quercetin while also consuming citrus fruits or Vitamin C supplements may have some issues involving oral sores, upset stomach or headache. Since Quercetin may have an effect on blood flow, it is best to avoid this product if you are at risk for blood clotting or if you have high blood pressure.

Quercetin may also hamper the effectiveness of some antibiotics. If taking Felodipine or any antibiotic medication with regularity, it is best to discuss this supplement with a doctor. Anyone doing hormone replacement therapy must not take Quercetin, as it will interrupt the flow of estrogen in the body and could cause an imbalance. Quercetin should not be taken by women who are pregnant or nursing.

Allergie help
Noticeable improvement in my nasal allergies. No noticeable taste.*

Great Allergy Relief!
I use Quercetin as part of my herbal allergy relief regimen. This product is a great alternative to capsules, and a lot less expensive. It doesn't have any taste, so I can just add 500 mg to my morning and evening tea. I am hypersensitive and I don't get any side effects, so it must be very pure!*

On 10/9/2016 ZenRuth said...

purity and good price
I have been taking Quercetin for only 2 weeks and noticed a decrease in wheezing, coughing from asthma and allergies. I have had severe asthma for 8 years and Quercetin has been the only natural compound that has made a difference. I am so thankful that I can breathe better. I could not take other brands that were made from fava beans but this one from the Sophora Japonica flower buds is doing fine and it is affordable. *

On 9/14/2016 Evanir said...

quercetin powder
I enjoy them since it does not have other fillers in the powder (capsules or tablets have many fillers in them). There is some questions regarding lipophilic nature of Quercetin for absorption in G-I system but it melts well in my hot tea and other drinks with no trouble. It is a good quality product.
Thank you. Kay*

On 9/5/2016 kay said...

Quercetin
I have used other brands and none helped so since this brand helps tremendously I have to assume that the other brands were full of fillers. My allergies started going nuts again a couple weeks ago and this has really helped. I also have a cat that can't go without.*

Quercetin Dihydrate Price and delivery are unbeatable.
I ride Bicycles and I use Quercetin Dihydrate for Athletic Endurance

Researchers from the School of Applied Physiology at the Georgia Institute of Technology found that, on average, “quercetin provides a statistically significant benefit in human endurance exercise capacity (VO(2max) and endurance exercise performance).
Other studies also show that quercetin helps increase immune function and prevents susceptibility to illnesses that can occur when someone trains intensely and experiences exhaustion. One study found evidence that taking 500 milligrams of quercetin twice daily helped protect cyclers from developing exercise-induced respiratory infections following periods of heavy exercise.*

I WAS REALLY HOPING!
I have had adverse reactions to every brand of quercetin I've tried and was hoping that this one would be different. It was not, I regret to say. I use several BS products and I'm very satisfied; but unfortunately, I can't use this one - head ache and nausea. I will continue to use the ones that I have been using and will try new ones as the need arises!

Quercetin
How wonderful to get amazing supplement in bulk form. Works wonders for me and I take it every day.*

On 5/23/2016 Maud Steinberg said...

Got this to combat seasonal allergies.
I've been using it for 10 days and so far haven't had any seasonal allergy symptoms. I wish I knew about it sooner. Benadryl was making me drowsy and allegra was making me senseless. It's wonderful to have my senses and no allergy symptoms.*

Quercetin Dihydrate arrived and I couldn't be happier!
Received our bulk order so fast, I was amazed, great customer service too because I had questions and the chat line helped answer them immediately. No flavor so my husband was even happy to start taking it daily (he is a tough one to convince if he doesn't like it no matter how much it will help him with his health issues). A little tough to stir up, just keep at it and eventually it will be enough to drink it down. I use a shot glass size of water, stir until dissolved, drink, add more water to get remaining out of glass. *

On 3/6/2016 Delia said...

good product
I ordered the quercetin due to my doctor's recommendation to help with my hay fever symptoms. I searched on the web and found out ordering from bulk supplement web site would be the most economical way. The order processed so fast and shipped right away. I got it in only a couple of days. The power mixes well with water. The only drawback is that the bag won't zip well after being opened. I don't know how it will help with my allergies with only a couple of days' usage. *

Essential for son's allergies
My pre-teen son may often poo-poo the hassle of taking his vitamins, but there's no question that he appreciates his quercetin. When he forgets to take it, his respiratory allergies flare up very noticeably. We stay stocked up on quercetin at all times.*

On 2/1/2016 Thomas said...

Powerfull Antioxidant!
By itself, Quercetin increases brain & muscle mitochondrial biogenesis, speeds up bone fracture healing, reduces diabetic neuropathy, systolic blood pressure, and sarcoidosis, to name just a few!
It works well in conjunction with other substances like; Glucosamine & chondroitin, rutin, catechins, and curcumin, as well as resveratrol & green or black tea.
I buy from no other source than Bulk Supplements. #1, and top of my list is the Quality. Price, packaging & customer service is 5-star for all. No other company comes even close!*

Razor burn reduced...
Only been taking it for about 2 weeks at suggested dosage on empty stomach first thing in morning, but I see noticeable reduction in razor burn, almost zero, when I shave later in the morning on a used razor (like most guys, i tend to use the same razor for as long as possible).

Reports state that bioflavanoids (quercetin, rutin, etc) reduce inflammation and, to me, this is the most visual proof of that effect. Will definitely continue product. I also take bioflavanoids to help out the Vitamin C in my program (2 grams a day in divided doses, full stomach). My skin definitely looks better recently and pores seem tighter.

Best of luck with your experience! *

Quercetin Dihydrate Powder
I started taking it right away. I really cannot say yet whether it is helping my environmental allergies or not yet. I did go Mall Shopping and I usually get a headache in stores and I did not get one. I need more time to determine if it is really helping me or not. I will update this review at a later time if I am allowed to do so. I love Bulk Supplements!!!*

On 12/20/2015 Laura said...

great addition to to your diet
this is a great addition to your diet to help with the absorption of important nutrients like turmeric and vitamin c, and is a very effective anti-inflamatory, and as usual Bulk
Supplements gives the purest product as well as the most efficient shipping available. As a personal trainer, I advise my clines to check out this company for any nutrients they may need, and they have never been disappointed.*

It is the best product for me
In my opinion, this product deserve 5 stars. It is the far best working supplement I have ever used.

I was lucky to get offer for BulkSupplements to try one their product free. After some research on BulkSupplements web-pages I choose the Quercetin product. Other their products somehow I know, already. I got the free sample 50 g of Pure Quercetin Dihydrate Powder pack from BulkSupplements to test it. Delivery was also free, very fast (1 day) and packing as good as usually from this company. The quercetin was packed as very fine, yellow and dry powder in sailed plastic bag with reusable closure.
The original packing is good for storing and shipment but it is not so convenient for daily usage. I have many empty colored containers from different already used supplements tablets and I got the powder in one of it.

I have started to use this product right on the delivery day and was surprised to get some positive results in a few days, almost right from the start. I have asthma for 3 years. I’m trying not to use steroid medications and by using some supplement products I keep the disease under control. I have now no problems at all. Ok. Is it the effect of quercetin?
It is not easy to confirm or get proof benefit from using quercetin, because I use some other supplements on daily basis, too. But the other supplements I’m using for a long time but using quercetin I have started first now. Now it is almost two weeks and the positive results stay and they are like never before. This inspired my curiosity to get more information about this powder.

On the BulkSupplements web-pages you can find a basic short information about their products and it is good, but if you need more deep information look in internet. Here are some of my favorite links:

1. University of Maryland
umm.edu/health/medical/altmed/supplement/quercetin
2. Linus Pauling Institute
www.lpi.oregonstate.edu/mic/diatary-factors/phytochemicals/flavonoids#introduction
3. www.lifeextension.com/magazine/2012/9/quercetin-broad-spectrum-protection/...

A short summary:
Quercetin can be found it in many plants and foods, such as buckwheat tea, onions, green tea, apples, barriers, red wine and others. Is also used to increase endurance and improve athletic performance.
Quercetin is a plant pigment (class: Flavonoid or Bioflavonoid, subclass: Flavonols) naturally occurring plant metabolites. There are approximately 4000 flavonoids and they are responsible for color of many flowers, vegetables, fruits and or roots. In alternative medicine bioflavonoids have been used as an aid to enhance the action of vitamins, as an antioxidant, for treating chronic infections, allergies, conditions of the heart and blood vessels, cancer, bacteria, viral infections, and other inflammatory conditions.

The form of Quercetin Dihydrate has to the apparent best bioavailability and is the most well researched of all Bioflavonoids. Many animal studies shows that Quercetin has many positive properties beneficial for health like antioxidant function, decreasing inflammation, decreasing platelet aggregation, anti-aging function, lowering cholesterol, reducing allergic reactions, boost immunity, protect the cardiovascular system, lowering blood pressure, treating neurodegenerative diseases, and other, but the results of this studies are not unambiguous for humans. For example, the antioxidant function is very big in the test tube but small or negligible in humans. It is suggested that it is because of low concentration of it in tissue, resulting from small absorption to human body in intestine. The biological effects of the flavonoids appear to be related to their cell-signaling pathway rather than their antioxidant activity.

Other issue are the possible side effects. Quercetin is generally consider safe, but taken at very high doses (greater than 1 g per day) may damage the kidneys, and the same is true for many supplements and vitamins, too. Further, it is suggested that you should take periodic breaks from taking quercetin and children and pregnant and breastfeeding women and people with kidney disease should avoid quercetin.

Quercetin can increase or decrease effect of some medications and other supplements. There are some possible positive or negative interactions with some medications and it is recommended to ask your doctor before use of quercetin.
Some studies indicate that taking supplement of quercetin and vitamin C decrease the intestinal absorption of vitamin C. For this reason, to maximize absorption of minerals and vitamins from supplements and meal this different products should not be taken at the same time. On the other hand you can buy many quercetin supplements where quercetin is combined with vitamin C. (?)
Here we have pure product and we can used it like we want. Anyway, I suggest: not take more than 1 g a day, take a break of it after one month for 1-2 weeks and be careful to your body signals.*

Quercetin
I have been using quercetin at the first sign of respiratory distress for years now, after reading an article in Pubmed which demonstrated that humans under stress given quercetin and exposed to cold virus, did not contract the cold. Its been an enormous help, primarily for my daughters as schoolgirls.

When I ran out of capsules, I was pleased to find quercetin offered at Bulk Supplements as a powder.

Lovely to have it without questionable fillers!

I mix it now with water, a bit of ascorbic acid and honey.
Makes for a fresh tasting, sunny yellow drink that my daughter enjoyed.
So much nicer than swallowing a capsule.
And even nicer to have symptoms (a cough in this case) abate

I'd like to add that my order arrived promptly

Quercetin
This is a very light weight supplement. I purchased grape seed extract at the same time as quercetin, and the volume per weight is almost double. The flavor is very neutral, and the powder is extremely fine, so it mixes easily. I am very happy with this product and the pricing, and the product is well packaged.*

QUERCETIN
First let me say this is my first review ever about any supplement and I take all kind of supplements.

So believe me or not it works like magic.I highly recommended this product for seasonal allergy. Thanks to bulk supplement for providing us clean products.*

Fine light yellow powder seems like the best part of an apple
By itself, quercetin increases brain and muscle mitochondrial biogenesis and exercise tolerance, speeds bone fracture healing, offsets the increase in susceptibility to N1H1 infection associated w/stressful exercise, has vasodilator effects on vessels, is gamma radioprotective, and improves the intestinal barrier.

By itself, quercetin also is an antioxidant, gives plants their color, reduces diabetic neuropathy, bacterial prostatitis, systolic blood pressure, plasma-oxidized low density lipoprotein, sarcoidosis, chemically-induced kidney damage, liver cirrhosis complications, ammonium fluoride complications, methylmercury, NaF, and cadmium poisoning, cardiac hypertrophy, alcohol-induced cognitive dysfunction, periodontal pathogens, excitotoxicity, leukemia, COPD, and insulin-stimulated glucose uptake in fat cells.

Quercetin does many things in conjunction with other substances:
1. With glucosamine and chondroitin, improves osteoarthritis and rheumatoid arthritis.
2. With rutin, reduces problems associated with asbestos as well as hyperuricemia and renal dysfunction due to fructose intake.
3. With catechins, reduces the effects of organochlorine pesticides.
4. With curcumin, reduces inflammation due to arthritis, liver radiological changes, ischemic kidney injury, and improves the color of the blood and the liver.
5. With onions, reduces serum uric acid and oxidative stress.
6. With pterostilbenes (resveratrol), reduces metastatic melanoma and is anti-obesigenic. (High doses of this combo are not toxic).
7. With sulforaphane, inhibits pancreas cancer stem cells.
8. With EGCG, inhibits prostate cancer stem cells.
9. With Green tea and folate, inhibits vitiligo.
10. With Black tea, reduces bisphenol-induced toxicity.
11. With Luteolin and bilirubin, inhibits the uric acid enzyme, xanthine oxidase.*

I have used quercetin for years. I ran out and decided to take a break from it. I felt much worse. This is a relatively costly supplement, but then I found bulksupplements. Buying it in the powder form is much more economical. The powder is tasteless, so it is very easy to take. This quercetin is effective also. I noticed a positive difference very quickly. *

I mix this in with my grape seed extract in my smoothie for a daily dose of good antioxidants. I am trying to get rid of capsules because too much magnesium stearate is not good for your digestive track. This is not only more cost effective, but is pure quality. I am very happy to have found a place that sells this. Customer service was also great in answering all my questions about the origin and quality control of their various products before I purchased. Very happy overall. Thanks!*

using as a supplement for my horse
quercetin is recommended for horses with allergies, so I am trying it. the bag arrived very quickly and the product is uniform in texture (powder) and color. it has no taste that I can notice, and the horses are eating it in their grain fine. for people, it would be easy to blend into a smoothie. although I don't think it would alter the taste or texture, it is bright yellow and might look unappetizing in a green puree. the dose of 1/4 tsp measured easily in a metal spoon, not caking or heaping and tapping right out. *

I ordered this supplement because I understand it has cancer fighting properties and I was grateful to find it in powder form and at an affordable price compared to most pill forms on the market. It came quickly, was perfectly packaged and appears very fresh. It is very easy to take.

Thank you for your great service and products.

Great quercetin
I'm very happy with your Quercetin. It has the sweet smell and bright color of fresh herb. The texture is very fine so that I have no trouble mixing it thoroughly in water, fruit juice or the raw applesauce I make in a blender. I increase its bioavailability by taking it with a Bromelain supplement or by mixing it with my applesauce (which itself contains Quercetin).

In recent years I have tried to arrange it so that I am getting most of my supplements in powder form so as to avoid all the unnecessary and dangerous additives found in most supplements that are sold as pills or capsules. This is why I was delighted to find BulkSupplements.com.

best quercetin quality to date
this product is a must have, i use 500mg and mix it in my preworkout drink and I can tell when I don't use it. I feel better while doing cardio, less fatigue and with more energy. I read is also a great antioxidant and if you mix it with other antioxidants (I mix it with vitamin C and resveratrol or grape seed extract) it tends to outperform the antioxidants by themselves, so is worth a shot...*
