However, many dietary supplements contain ingredients that have strong biological effects that may conflict with a medication you are taking or with a medical condition you may have.

The FDA and the Federal Trade Commission may also take regulatory action against manufacturers who make unsubstantiated weight loss claims about their products. The FDA does not allow dietary supplements to contain pharmaceutical ingredients, and manufacturers cannot promote dietary supplements to diagnose, treat, cure or prevent any disease.
The FDA is the federal agency that oversees dietary supplements in the United States. Unlike over-the-counter and prescription drugs, which must be approved by the FDA before they can be sold, dietary supplements do not require review or approval by the FDA before they are placed on the market. In addition, manufacturers do not have to provide proof to the FDA that their products are safe or effective before selling them.

The interpretation of the results of these studies is complicated by the fact that bitter orange is almost always combined with other ingredients in supplements for weight loss. After 6 months, those in the treatment group lost significantly more weight (mean weight loss of 5.3 kg) than those in the placebo group (2.6 kg) and had a significantly greater reduction in body fat. In general, clinical trial results do not support a clear relationship between higher calcium intake and lower body weight, prevention of weight gain or weight loss.
