First off, each serving comes in a cute, single serve pouch of its own. It was very easy to use, you just pour one packet into a 16 oz bottle of water and it's ready to go! It really did keep me hydrated and I noticed I had more energy as well. The only downside (for me) was the taste. It was too strong for me. Other than that, I think it did what it said it would do! It was effective, and because of that I would recommend this product!
