Complain
Caused me stomach pain
This upset my stomach for the days I took it
I discontinued it as it was making my stomach more sensitive
Very expensive
While it is more expensive than other brands on the market
What a waste of money
I have histamine intolerance
recently had 2 insect bites on my legs which were very inflamed and extremely itchy
prone to eczema
This upset my stomach for the days I took it
No effect
on average only around 2%-20% of it gets absorbed
Quercitin is very hard to absorb
It's either not from Sophora Japonica or it is a less absorbable form of quercetin
