The shakes have approximately 21 servings so 1 tub will last you around 2 weeks if you're replacing 2 meals a day! The PDM has 42 servings if you use 1 scoop to add to your shake. The tea and the aloe both have approximately 30 servings for an adequate daily fluid intake so it's all down to personal preference on how many teas you have a day and if you add the aloe to your water throughout the day!
