Quercetin is a nutritional supplement that is derived from plants and fruits. This article will tell you about the varied quercetin side effects.
Quercetin is derived from plants and fruits and works as a natural anti-histamine and anti-inflammatory supplement. It is also a powerful antioxidant. The uses of quercetin include:
- Relieving allergies and asthma symptoms
- Reducing arthritis pain, fatigue, anxiety, and depression
- Aiding men suffering from prostate problems
- Recent studies show that it might prevent signs of cancer from appearing
Quercetin is found in apples, red wine, tea, onions, and berries. However, there are some quercetin side effects that have been noticed in people who take supplements that contain it as an active ingredient.
Some people experience allergic reactions that include symptoms that could consist of one or all the following―rashes, itching, difficulty in breathing, wheezing, hives, mouth sores, and swelling of the tongue, lips or throat.
Quercetin adverse effects also include nausea, vomiting, and dizziness. In extreme cases, it could also lead to vertigo and migraines. All these signs are usually accompanied by sweating and flushing.
People who have a weak or sensitive digestive system should be aware that one of the quercetin dihydrate side effects is also stomach discomfort. Quercetin could lead to indigestion, acid reflux, heartburn, and stomach upset. This has been seen to happen especially when taken on an empty stomach. Thus when one takes any quercetin supplements, it is important to take them in between a meal. In this way one could avoid this adverse reaction.
Administering very high dose of quercetin has known to lead to kidney infection. Although this is extremely rare, it is always a good idea to be cautious of this side effect.
In some cases, if the right dosage is not given, then quercetin could also lead to a pro-oxidant effect. Which means that the positive effect that quercetin is supposed to have―like inflammation reduction―actually turns into an adverse effect. So instead of reducing inflammation, quercetin might cause it. Thereby negating the very purpose of administering the drug. Thus to avoid this effect, make sure that quercetin is taken in small doses.
Quercetin supplements may lead to an increase of estradiol (sex hormone) in people. Especially in those who are on hormone replacement therapy. And by doing that, it will reduce the effectiveness of other estrogen forms. All this leading to hormonal imbalance.
Side effects also include experiencing joint discomfort and pain. This can happen if quercetin supplements are taken over prolonged periods.
In some rare cases quercetin has been known to inhibit the functioning of antibiotics in the body―such as fluoroquinolones. So also, it may affect some people who suffer from high blood pressure.
The best option to avoid facing any of the side effects is to take it in small dosages. Quercetin works best if taken in combination with a bioflavanoid like rutin, hesperidin,, or bromelain. This helps the system absorb and digest the quercetin supplement more effectively.
The next time you think about starting a quercetin supplement, keep in mind the above mentioned side effects before administering any sort of dose. It is always best to remain cautious and consult a doctor before taking any such steps.
