 Well, the powder is just super easy to store and transport. It mixes really well with the frother that we send you free, and it also has no flavor at all. So it basically just dissipates into the water when you mix it up. So it's like drinking a glass of water at bedtime. A lot of people who already have several medications that they're taking at bedtime, or maybe you just have trouble swallowing capsules, that powder is a really awesome option.
