After having my son, I was drained and lacked energy. I tried this product and fell in love with it. I buy the canister which gives you more bang for your buck. You can get about 42 servings which makes it about 1 or so a drink. I love the scooper they now have because it makes it convenient to pour in a water bottle. Blue Raspberry and Fruit Punch are my favorite. I use half a scoop and I have tons of energy (good energy, not jittery energy) and can get through work with ease.
