Quercetin, Zinc, and Vitamin C have been the news as natural COVID treatments. What exactly is Quercetin and what does it do you might ask?
Quercetin is a plant pigment found in fruits and veggies such as kale and berries that helps keep the cell membrane stable. When a cell membrane isn't stable it is difficult to maintain proper nutrition inside the cell itself. The cell membrane is made of phospholipids. When quercetin is paired with a phospholipid it is better absorbed.
Quercetin is a also zinc ionophore which means that it helps zinc get into the cell by increasing the permeability of the cell membrane or binding to it. When taken with Vitamin C it reduces oxidative damage caused by free radicals, whether naturally occurring in the body or environmental.
It is important to remember that dietary supplements are regulated by the FDA as food, not as drugs. Supplements may also interact with medication so be mindful of reading labels when you are taking vitamins without guidance from a practitioner.
