How does quercetin work?
Research shows that anti-inflammatory foods containing quercetin may treat conditions associated with heart and blood vessel disease, allergies, infections, chronic fatigue and symptoms associated with autoimmune disorders such as arthritis. Can flavonoids like quercetin really be beneficial to the human body?
All its beneficial properties as an antioxidant come down to the ability to “devour free radicals.”
As a major bioflavonoid in our diet, quercetin (a type of "polyphenolic antioxidant") slows down the aging process because it reduces oxidative stress in the body. ()
These processes occur in every body, but the associated negative effects increase in the presence of factors such as poor diet, high stress levels, lack of sleep, and exposure to chemical toxins.
Overdose
Bioflavonoid, obtained from food, even in large quantities, is not capable of harming the body. However, tablets taken in high doses (over 4 g daily) can cause an excess of the substance.
Attention! There is not yet enough information about the consequences of an overdose. It is assumed that the symptoms of excess manifest themselves in the form of adverse reactions, only in an intensified form.

Reviews about the application
