I'm not sure that the use of Taurine is directly related to weight loss. Also, it retains water in your muscle, which means that it draws water into your muscles, so it would not be effective in draining water from your body. I have used taurine before for weight lifting. I experienced higher levels in energy and higher gains in muscle mass. So it definately helped me to have more energy and build more muscle. It is used in the nervous system for functioning. Are you drinking enough water? Believe it or not, sometimes, the cure for relieving bloating and water retention is drinking a lot more water. It sounds like you may be dehydrated, and I won't go into too much detail, but I would suggest drinking more water. I have a couple hubs on weight loss and health if you are interested. I know a pretty good amount of information on weight loss and fitness as it is one of my expertise. If you would like me to write a hub on something specific then message me and I would be happy to help.
