A cup of red onion has a little over 100 grams. However, the quercetin in natural foods is more bioavailable than in supplements, so you don't need as much.
How much quercetin do we need a day? Not for Covid. I read it’s around 18-24mg? Isn’t 500mg a lot more than we need? Or is that only when you have Covid?

I eat apples, onions, blueberries, broccoli, bell peppers, tomatoes, and pistachios regularly. All of those foods contain quercetin.
I occasionally take a supplement but not on a daily basis.
What makes you decide to take supplements?
Days I don't eat enough veggies for whatever reason.
