A friend introduced me to Verma-Plus when we lived in SE Asia (where contracting parasites from the food supply is a given!). I have used it consistently since then because it is effective in eliminating the "unwanted guests" and keeping my "innards" functioning consistently. The only downside is that the taste is less than pleasant (but it grows on you...like the little bugs inside!). I'm not a juice drinker, but adding it to something sweet and fruity may help mask the strong flavor. It is a bit expensive (especially with the shipping cost factored in), but a few drops each day goes a long way.
