I believe (don’t quote me here) but even an rx drug like metformin it’s hard to go hypo with cause your body will shuttle glucose from the liver if it gets too low
That doesn’t mean it’s not working
A better indicator would be eat a Normal carb meal let’s say your pre wo meal wait 20/30 min test blood sugar
Then do the same thing the next day with either berberine or metformin or what ever
It should be significantly lower but not hypo
Ie 160 without 105 with
At least this is my understanding
Never intentionally make your self hypo especially alone
You will go into a coma or die
yes that is very true and never have read this on metformin either. And I more so mean the sensation or perceived feeling. Don’t think these supps are strong enough to induce an insulin like hypo event .
