What supplement has replaced ephedra after it was banned?

Bitter orange is considered to have replaced ephedra as a popular ingredient in weight loss supplements following the ban of ephedra due to safety concerns. Ephedra was known for its stimulant effects and was often included in products aimed at weight management, but it was associated with serious health risks, leading to its prohibition.

Bitter orange contains synephrine, which is structurally similar to ephedra and is thought to have some stimulant effects that can aid in weight loss. However, it is important to note that while it may mimic some of ephedra's effects, it is generally regarded as having a different safety profile. This has made bitter orange a common substitute in many formulations targeting weight loss.

The other options, while they have different intended uses, don't serve the same role as a direct substitute for ephedra in weight loss products. Sibutramine and orlistat are primarily prescription medications used for obesity management and weight loss, with distinct mechanisms of action and regulatory statuses. Ginseng is known for its general health benefits and energy-enhancing properties but does not have the specific weight loss focus associated with bitter orange. Thus, bitter orange has become the favored alternative in the market after the restriction on ephedra.
