Because weight loss supplements are not usually reviewed by the FDA, you must use caution when taking these. They are not subject to the standards that other medications must pass. Only if they are deemed by the FDA as not being suitable for human consumption would these supplements be discontinued from being sold.

Ephedra has been banned as a weight loss dietary supplement and in its place, some are promoting bitter orange. However, bitter orange has recently been shown to possibly produce similar effects on the body as ephedra, making it an ineffective and possibly dangerous weight loss dietary supplement. So far, bitter orange is still available for purchase, but it may not be available for too much longer.

Guar gum and chitosan have been shown to be two very common but ineffective weight loss dietary supplements. Ingestion of these two dietary supplements for weight loss is not encouraged anymore. Their long term effects on the body are not known since neither of them has been studied or tested for that in particular. However, it has been shown that they do not contribute or help dieters to reduce appetite or lose weight.

St. John's Wart and green tea are reportedly helpful in weight loss. When used together with diet and exercise both of these have proven to be effective weight loss dietary supplements. Green Tea can come as pills and patches if you would like a change from the traditional tea form.
