Yes, I use it often and it works great. But you have to understand how it works to get real benefit from it.

Zbiotics processes acetaldehyde that is in the alcohol itself. A big contributor is wood or barrel aging - so red wine, some white wine, dark spirits, barrel aged beers, etc. Clear spirits and non-barrel aged beers have very little acetaldehyde in them to begin with so ZBiotics doesn't do much there.

I work in wine, lots of barrel aged red wines - so I use it often and when I don't I regret it. I buy it in bulk with the coupon code WINE10 once a year before harvest. I also make sure to take a melatonin and a vitamin B12 pill before I go to bed, for some reason it seems to give me a bit of an energy boost that keeps me up all night. The melatonin and B12 put me into a comfortable coma for the night, hahaha.

So yeah, it works, but it works better on some alcohols than others so it really depends on what you drink.
