You can use your favorite brand of shake to get your morning boost of caffeine. I like to use Premiere because they have about 30 grams of protein in one shake. If following low carb diets, it also only has 6 carbs! When counting macros or for weight loss, check your brand of shake for amount of grams of protein, calories, and other nutritional values that are in the shakes you're using to make sure you are getting a good amount of extra protein boost.
