Oz's website lists 1 cup grapefruit juice (100% juice not grapefruit juice cocktail or any pineapple alternative) and 2 TBSP (tablespoons not teaspoons!!) apple cider vinegar. The 1 tsp of honey is optional and added only if it's too tart for you. It's suggested to drink before every meal. For more info and to see the benefits of this drink, see Swimsuit Slim Down Plan tip #1 on the Dr Oz website link on this page.
