One more thing, a friend who is positive and who works out regularly like I do, said his energy and general outlook has been greatly increased by an over the counter product, that body builders looking to loose fat use, called Hydroxycut. Since you've gotten some feedback on the first question - I will tackle the second. Body-building products are usually a combination of herbal extracts, vitamins, minerals, ect. Carnitine is an amino acid that the mitochondria uses to shuttle fatty acids - body builders like to use carnitine because it may promote lean body mass by increased utilization of fat in the mitochondria. Chromium picolinate is a trace element that increases insulin activity -again, body builders like this because it may promote lean body mass by increased utilization of glucose.
Citric acid is used by the mitochondria to generate energy.
Overall, Hydroxycut is probably not harmful unless you have a heart condition that is exacerbated by MaHuang.
