Life Extension Optimized Quercetin Reviews

Ever since we were little, we are always reminded by our parents to consume enough fruits and vegetables regularly. But did you know why?

Because fruits and vegetables are part of a healthy, balanced diet that would help us be in our optimal physical condition. 

They are a good source of vitamins, minerals, and antioxidants that help boost immune function and avoid a health problem.

So what is an antioxidant?

Like the vitamins and minerals needed for physiological functions, Antioxidants, also known as phytonutrients are a plant-based substance that plays an essential role in maintaining health and preventing diseases.

However, according to the World Health Organization, about 8 out of 10 individuals are not getting the recommended amount of fruits and vegetables daily.

Luckily, supplements have been available in the market to ensure that we have an alternative source where we can get additional nutrients for added health benefits. 

Here, we will provide you an in-depth review of a plant-based dietary supplement manufactured by the life extension brand, their optimized quercetin. 

If you’re interested to know more about its benefits and function, keep reading.

What Do People Say About It?


Life extension optimized quercetin has garnered quite a high customer rating on Amazon. 

A customer from the United States has expressed her satisfaction with the product and has written:

 “Love these, they are really helping me and such a great value!”

Another feedback from a verified purchaser from the United States:

“I’m kind of a supplement junkie. This one has become one of my staples. This is a super supplement in my mind. It’s a superior antioxidant that attacks those darn free radicals, thus helping with inflammatory responses. Because my skin is on the pink side, and my gut is out of whack, I get flushed a lot. After taking Quecetain for a while (I take 2 a day for a total 500mg dose), I find that I’m nowhere near as red as I have been in the past. There are 60 pills in a bottle, so you need at least a bottle a month, but your health is worth it. You should get some.”


Here is a short video clip from Life Extension about the benefits you’ll be getting with optimized quercetin capsules.

The Verdict: Should You Buy It?

Supplementation can be a great way where we could obtain nutrients when we struggle to get enough from our diet.

Since we are amid Covid 19 pandemic, I think it is important to be extra vigilant and careful about our health. 

What’s good about life extension optimized quercetin is that it is Non-GMO, safe for vegetarian and gluten-sensitive people. It may also help lower chances against certain cancers, cardiovascular diseases, and other health concerns. It could provide extra protection against viruses and diseases by boosting immune functions. 

However, aside from supplements, we should always remember to practice these things: Proper eating habits – consuming everything in Moderation, Variation, and Balance. Regular exercise, having enough sleep at least 7-9 hrs, and avoiding stress as these are the key for optimal health. 

Please keep in mind the importance of safety precautions when taking a supplement. Always consult your health care provider before taking any products.
