Identity and form
Ephedra refers to Ephedra botanical material; FDA banned dietary supplements containing ephedrine alkaloids in the United States in 2004.
The label should identify the source, form, preparation, and active or marker amount when those details determine comparability.
What the evidence can answer
Human research has examined Ephedra in relation to exercise performance and recovery, cellular energy metabolism. The amount, source, preparation, population, comparator, and measured outcome determine whether a result applies to a finished product.
Current WQ evidence label: Insufficient human evidence. This label describes the present evidence context, not a promise of benefit.
Safety and decision context
Regulatory / restricted context. U.S. dietary-supplement status or permitted-use conditions require current regulatory review. Total stimulant exposure, cardiovascular history, and interacting medicines matter.
Review medicines, pregnancy or breastfeeding, allergies, medical history, and the complete finished label with a qualified professional when relevant.
