Since Skinny Up! is all-natural and hormone-free, there really aren’t any side effects. However, since candida is being killed at a high rate and fat cells are being cleaned out of the toxicity they hold, a person can experience flu-like symptoms in the first week of the Reduce Phase. Other candida die-off symptoms can include mild headaches and mild fatigue.It is also important to know that between the Skinny Up! products and the Skinny Up! protocol,  major detox happens, especially during the first week. For years, the body packs away not only stored nutrition, but also toxicity from foods you consume, medications used, old hormones, and remnants of toxicity that entered the body through breathing or through other means. During the Skinny Up! process, all of that... the good, the bad, and the ugly, have to be sorted out (primarily by the liver) and either consumed as energy, or sent out of the body for good. This is typically a healthy thing, even though it can be uncomfortable for some during that first week or so.As always, we at Skinny Up! highly encourage and recommend that you speak with your primary care physician before starting Skinny Up!. You can view all of the ingredients for the Skinny Up! products by clicking here.
