I remember those! They were called Beer Neutralizer. If it's the ones I'm thinking of, a 30ct bottle with a cheesy label and the dose was like 3-6 caps.
It was just a carb cheat formula but geared specifically for alcohol. It had Chromium, Activated Charcoal, Kidney Bean extract, stuff like that. Basically an insulinomimetic, an amylase inhibitor, vitamins and a toxin adsorbent. Think I still have half a bottle in the kitchen somewhere.
