Quercitin has a great reputation lately. I found this product to have an attractive appearance and scent. Nowadays, it tends to sell out quickly. And you can find incidents of price gouging by people grabbing it up on iHerb and re-selling it on Amazon (at least in Japan.) So grab it when you can!

I asked the manufacturer and they replied “Natural Factors Quercetin is sourced from the budding flower of the Pagoda Tree (Sophora Japonica). Natural Factors Quercetin is not derived from onions or garlic.” Which is exactly what I am looking for! Also it is up to 10 times higher absorption than standard quercetin and has a unique, patent-pending LipoMicel technology provides enhanced bioavailability and stability. Recommended!

I've been taking this quercetin for a year now, along with vitamin D3 and zinc. Have not had a cold or flu the entire time, even while those around me have been quite sick. The soft gels are fairly large, so if you're not used to swallowing larger capsules it may take a couple tries to get used to it. Good natural way to bump up your immunity.

The unique technology in this supplement allows greater absorption and thus improving its effect on the so called "Senescent Cells" that refuse to die and take up space in the body; in particular your organs. They are part of the ageing process, and thus another health issue that needs addressing. Whether you want your body to function at the optimal level, all depends on what you want to do, to reduce the dysfunction of cells and toxic build up that occurs as we age. Administering Quercetin into your supplement regime, is proving to be a pivotal approach to achieving this.

This is one of the best products on the market. It is easy to take and digest. Quercetin can be found in apples and onions but to get the benefit that this product provides, you'd have to eat tons of apples and onions (not together!). It's really wonderful.

In combination with other supplements, this helped me overcome Covid-19 in a few days. Great quality ingredients and also benefits my allergies, so I’m continuing to take it every morning. The capsule size might be a problem for people that find it hard to swallow. No taste as it’s a capsule.

This product was delivered ASAP!!!! When I could not find it anywhere else iHerb had inventory. This brand of quercetin has helped me tremendously not only with my COPD but also with my post covid issues. The quality of this product has proven to be second to none. The ingredients, after research, are the best there is.

I buy antioxidants to help my body with aches and pains. I have inflammation and I feel they help with that. If I stop taking them I find it very hard to get up from my bed. Get around alot easier. Contains no artificial preservatives which is great. 10 x the absorbtion which is good too.
