Hi. Just a warning about diet supplements. I took Xenadrine for a month to lose a couple of pounds and happened to go for a physical and routine blood work. My liver function tests were significantly elevated. First, without ephedra these pills do nothing anyway, Second, after being off the Xenadrine for two weeks the liver functions returned to normal. This is not a side effect that the product speaks about. Many people take these supplements and drink alcohol at the same time which may be toxic to the liver. Just a FYI.
