Good, easy way to take this supplement.
I order this type of Quercetin Liquid because I have issues with the large tablets. I like it, but it is a bit smaller than my previous choice. It has a nice mild taste and so far seems like a fine product.

Gave me hot flashes
I was really looking forward to using this but I had to discontinue after a week. It messes with your hormones and gave me hot flashes. It can also mess with your thyroid.

Great!
My partner and I both have severe allergies and this stuff has been really helpful! Did what allergy meds couldn’t, already on our second bottle.
