You’re exposed to free radicals every day‚ no matter where you live. There are natural sources of free radicals in the air that we breathe‚ but free radicals are also commonly derived from things like tobacco‚ heavy metals (such as mercury)‚ and pesticides. Free radicals are extremely reactive molecules that can cause disruption in bodily processes like the production of DNA‚ RNA‚ and fats. If this happens‚ your body can experience poor cell functioning and lowered immunity. One way to combat the effects of free radicals is to maintain a healthy‚ organic diet that is rich in antioxidants. Antioxidants neutralize free radicals‚ which can prevent or even reverse their potential damage.

It’s understandable that in today’s busy world‚ that you may not have time to eat a proper diet. Alternatively‚ you may have limited access (or no access) to organic‚ pesticide-free foods. This is where a supplement like Pure Encapsulations’ Quercetin comes in.

Quercetin is an antioxidant flavonoid found in fruits and vegetables. Flavonoids are what give plants their color‚ and have many nutritional properties. Since quercetin is an antioxidant‚ it’s helpful in neutralizing the free radicals in your body. It also serves as an antihistamine and anti-inflammatory. These qualities make quercetin a potentially effective way to reduce your allergy symptoms.

Quercetin also works to protect your arteries from harmful plaque buildup. Other possible benefits include:


  • Support for healthy blood pressure levels

  • Reduction of symptoms of bladder pain and the urge to urinate excessively‚ if you have a urinary tract infection

  • Reduction of prostate inflammation


These vegetable capsules provide you with 250 mg of quercetin. Every bottle of Quercetin contains 120 capsules‚ which should last between two weeks and one month‚ depending on your dosage. It’s recommended that you take between two and four capsules daily in divided doses between meals.

      I've been taking quercetin/bromelain for allergies for years. I have really, really bad seasonal allergies and I'm super allergy to cats. My housemate has one that sheds like crazy. I take these alongside Claritin for relief. I will be attempting to quit Claritin soon as one builds up a tolerance over time and it seems to stop working.

      Pros

      Cost effective, alternative to OTC allergy meds, natural, no fillers or binders

      Cons

      Nothing

      Since most of the reviews just rave about the histamine affect, I was hoping to hear more about the anti-aging effects.

      Pros

      Don't know anything about it.

      Cons

      Nothing as I know nothing about this and frankly do not want to spend $40.00 on an antihistamine.
