I've been thinking about taking the weight loss drink mix called plexus slim. Is this a safe thing to do? They claim it's natural

Safe to try, however. Please be aware the term "natural" on a food label is meaningless- foods with gmo's ; toxic chemicals are often labelled natural! however, plexus slim is natural ; appears to be safe. However, there is little evidence it works- see http://supplement-geek.Com/plexus-slim-review-ingredients-side-effects/ the key to losing weight is never a supplement but diet ; exercise- see comment for my advice:.
