good value

I've tried many different quercetin products. This one seems to provide the best value, and it is the one I am purchasing the most now. Quercetin has several benefits. I used it as a good anti-oxidant, for better histamine levels to battle allergies, and for its immune support and how it works in tandem with zinc. I like that the bottle contains 120 capsules at 500 mg each, and so I don't have to reorder as often.

Powerful Supplement

Quercetin is a plant pigment or flavanoid found in onions, apples, berries, grapes, and red wine. It’s a powerful antioxidant/anti-inflammatory that boosts your immune system and increases the mitochondria (the powerhouse of the cell) in your muscles and brain. This is one of the recommended supplement during the Covid lockdown and it sure helped us not getting Covid -

I like it

The capsules are a little large, but I can get them down. I like to take them when I do a "fisetin cleanse". I don't know if I'm actually getting benefits. I hope I am.

Low migraine frequency

I have a couple chronic illnesses stemmed from inflammation so I chose this to reduce the amount of flares that I had. A wonderful side effect is a reduction in my migraine frequency. I’m over 17 migraines a month but this has halved my flares
