Description

Thorne Quercetin PhytosomeWhen people tell you to eat dark leafy greens and purple vegetables, this is because of the flavonoids they contain (antioxidant pigments giving color to plants). Quercetin is the most abundant flavonoid found in plants, nuts and other naturally occurring food sources, such as honey. It is not often recommended by health care professionals as a key supplement because of its low absorption levels when taken by itself. However, Thornes Quercetin

When people tell you to eat dark leafy greens and purple vegetables, this is because of the flavonoids they contain (antioxidant pigments giving color to plants). Quercetin is the most abundant flavonoid found in plants, nuts and other naturally occurring food sources, such as honey.

It is not often recommended by health care professionals as a key supplement because of its low absorption levels when taken by itself. However, Thorne’s Quercetin Phytosome is combined with sunflower-sourced phospholipids to create a phytosome complex that can easily cross the gut barrier. Taking quercetin will boost antioxidant powers in your body from all angles, including reducing damage to fats, boosting glutathione levels, increasing antioxidant blood levels, blocking histamine (allergic reactions) and stabilizing mast cells (immunity).

With these capacities and more, quercetin is effective in protecting brain and gut cells, aiding in digestion and cardiovascular health, and is known to be a highly sought after anti-aging supplement.

Do it mayne
Size: 9.5" x 10.9" x 2.1"
Good quality and fit but find it funny that the instructions with the air flow are on the side. I assume that would be facing out and was annoyed when I tried to close and it didn’t fit. Probably should have read the directions. Still would recommend

Save money by installing yourself
Size: 9.5" x 10.9" x 2.1"
Good price and easy to install in a 2019 Honda CRV. Instructions can be found on YouTube. Much less expensive than having a service center install them.

Always fits and is easy to install
Size: 9.5" x 10.9" x 2.1"
We've bought these for years and they always fit and are easy to install. Easy to see when they are dirty and need to throw away. Embarrassed that we let the car dealership do it for so long. We set on six-month subscribe and save so that we know when to replace it - change it whenever it shows up!
