We love Spark! I enjoy the mandarin orange, pomegranate, and mango strawberry. My husband prefers the watermelon, pink lemonade, and fruit punch. It was especially helpful when I was trying to concentrate to study for my board exams. In addition to energy, it is great for concentration! Yes, it can be expensive, but as distributors it is much more reasonable. Definitely cheaper than a trip by Starbucks!
