The NIH database records one serving a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.

The Tolerable Upper Intake Level is the most of a nutrient per day, from food, water and supplements together, that is likely to pose no risk for almost all adults (Institute of Medicine, 2011). It does not apply under medical supervision. This page compares labels; it is not medical advice.

Directions
Directions: Add two heaping scoops of Serious Mass to a blender filled with 24 oz. of water. Blend for 45-60 seconds. Then add a few ice cubes and, if desired, other calorie-contributing ingredients (see “Supercharge Your Serious Mass” on the back of the bag) and blend for an additional 30-45 seconds. Tips: Mixing two scoops of Serious Mass with 24 oz. of nonfat or low fat milk instead of water will give you a thicker, creamier, higher-calorie shake. New users may find it beneficial to begin with 1/2 of a serving daily for the first week and then gradually increase to 1 or more full servings several times a day.
Between Meals: Drink 1/2 -1 serving of Serious Mass between meals to maintain positive nitrogen balance and support a high-calorie diet. Post-Workout: Begin drinking 1/2 -1 serving of Serious Mass 30-45 minutes following exercise to support maximum recovery. Before Bed: Drink 1/2 -1 serving of Serious Mass about 45-60 minutes before bed to provide nutrients to recovering muscle throughout the night. Note: For best results use Serious Mass combined with intense weight training (3-5 times per week) and a sensible whole foods diet. Also, keep in mind that sufficient recovery between workouts impacts your ability to gain lean mass. Allowing at least 48 hours between workouts involving the same body parts is recommended.
Supercharge your serious mass by adding one or more of these foods to your shake. Serving Size Calories 1/2 cup Granola 250 1/4 cup Chocolate Chips 198 2 tbsp. Peanut Butter 190 1 oz.
