Quercetin – nature’s helper in times of allergies and viruses
In recent years, a large number of biologically active substances of quercetin have been discovered, therefore the interest in its potential benefits on human health has grown significantly.
During the pandemic years, research has focused even more on this herbal ingredient to take advantage of its exceptional properties for immune system health. Quercetin, or as it is also called, the “king of flavonoids”, shows strong effects on several biological processes: on blood circulation, immunity, protection against exposure to viruses, metabolism and reduction of inflammation.
Unfortunately, like many other botanical extracts, it is hardly absorbed in its natural form.
Thanks to the unique Phytosome ® Quercefit ® technology from the flower buds of the Japanese sophora tree, by mixing this beneficial botanical ingredient with something that already exists in the human body – phospholipids , 20 times more bioavailable quercetin was obtained than unformulated quercetin.
Differences between phytosomes and liposomes

According to the study of 3 groups of participants (between 18 and 50 years old) who were orally administered a single dose of 500 mg of regular (unformulated) quercetin, 250 mg of Quercefit ® and 500 mg of Quercefit ® , it was confirmed that Quercefit ® maintains significantly higher plasma quercetin levels .
Quercetin offers an impressive array of potential health benefits, as it supports:
- Natural defense of the body during seasonal viruses
- Lung and bronchial tract health
- A healthy, normal immune response
- Normal histamine levels
- Alleviation of inflammatory processes
- Protection of cells from free radical damage
- Creation of new mitochondria in the brain and muscles
- Faster recovery of athletes after physical stress
- Healthy cell aging
- Protection against lipid peroxidation
- Metabolic health

How is Quercetin from Global Healing different from other supplements?
Global Healing’s priority is to provide the purest nutritional supplements that work and bring nourishment to every cell in the body.
They cooperate with small farms that grow wild and organic herbs with love and care. They select and test only the highest quality and purest ingredients, in order to obtain the most valuable from nature.
The strict production technologies they use are unknown in the supplement industry, such as triple distillation of water and the use of a cold extraction process, so that the heat does not damage the delicate ingredients of the plants. Raw essences from plant ingredients are obtained with the patented Raw Herbal Extract™ technology, leading in the industry, which preserves all the antioxidant values of the plant.
Their ingredients and packaging are always sustainable, recycled and have a minimal impact on the environment.
There are many dietary supplements on the market that contain synthetic quercetin. It cannot offer anywhere near as high a level of absorption and protection as Quercefit ® .
With phytosome technology using sunflower phospholipid lecithin, only active bioavailable ingredients are delivered to the cell, supporting the body’s natural response to oxidative stress.
Tips for taking Quercetin
It can be taken 1-2 capsules per day or as recommended by a health advisor
With food or on its own
Quercetin is gentle on the stomach and can be taken with or without food. For a better synergistic effect, it is often combined with Zinc, Vitamin C and Vitamin D3
Quercetin increases zinc concentration
Quercetin is known as an ionophore (carrier) of zinc. This means that it binds and enables easier passage through the cell membrane. Then zinc, which has an antiviral role, can stop virus replication more quickly.
Support during the virus
The synergy of organic zinc and quercetin provides strong immune support during viral infections , as well as in all types of inflammation.
