ADVOCARE- 24 Day Challenge AdvoCare is a premier health and wellness company offering world-class energy, weight-loss, nutrition, and sports performance products. I'm so glad I took that first step with the 24 Day Challenge. In my first 24 days, I lost 14 pounds and 16 1/2 inches! I know how hard brides work to look their best on their wedding day and I would LOVE to help you ladies reach your goals! Please let me know if you have any questions!
