Advocare Spark has changed my life! In February 2014 i was drinking 2-4 20 oz bottles of dr pepper a day. I had originally drank diet but switched to regular due to side effects. I put on several pounds with regular soda and then a friend introduced me to Spark. Within 2 weeks i had stopped drinking soda all together. Spark has the energy boost of caffeine without the sugar crash of soda. It give sustained energy and the B vitamins provide a mental focus that I just love. Although Mandarin Orange is the one listed here i actually love Fruit punch the best, and then grape, Mandarin Orange, Green Apple, Mango Strawberry, Pink Lemonade and Cherry in that order. I am a forever lover of Spark and as a by product of the stopping soda--- i lost those last 15 pounds that had been alluding me. Interested in Spark for yourself? seek me out.
