text: does herbalife products causes any side effects especially the shapeworks?thank you?   this really depends on the person.  you may be lactose intolerant, then try mixing the shake with soy milk.  if you feel nauseous after taking the supplements, try "herbal aloe drink".  consult with your distributor, or print out the product label for the products and show the ingredient list to your physician.  herbalife products are dietary supplements and are not medicine (not intended to cure or treat any disease).
