Dietary supplements are regulated by the FDA as food, not drugs. 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. Products containing hidden drugs are also sometimes falsely marketed as dietary supplements, putting consumers at even greater risk. For these reasons, it is important to consult with a healthcare professional before using any dietary supplement.

The FDA has developed these questions and answers (Q & A) to help consumers, health professionals and the general public understand FDA's actions regarding weight-loss products contaminated with various prescription drugs and chemicals.

Unfortunately, the FDA cannot test and identify all weight-loss products on the market that have potentially harmful contaminants to ensure their safety.
Compliance actions and consumer warnings for unapproved products only cover a small fraction of potentially dangerous weight-loss products marketed to consumers on the Internet and in some retail locations. The Food and Drug Administration (FDA) regulates dietary supplements, including those promoted for weight loss. Like other dietary supplements, weight-loss supplements differ from over-the-counter or prescription drugs in that the FDA does not classify them as drugs. Unlike drugs, dietary supplements do not require pre-market review or FDA approval.
Supplement manufacturers are responsible for determining that their products are safe and that the claims on their labels are truthful and not misleading. If the FDA considers that a supplement is unsafe, it can take enforcement action to recall the product from the market or ask the manufacturer to recall the product. 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 product, called Plenity and developed by Gelesis, has been approved for overweight or obese adults with a body mass index of at least 25, even if they have no other health problems.

However, when the authors analyzed the six studies that were conducted outside Japan (where the study methodologies were less heterogeneous than in the Japanese studies), they did not find statistically significant differences in the weight loss of green tea compared to placebo.
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.

Lorcaserin (Belviq brand), a previously approved weight-loss drug, has recently been withdrawn from the U.
