Ephedra contains ephedrine alkaloids that can increase metabolism but also raise cardiovascular risk. The FDA banned ephedra in dietary supplements in 2004 after reports of heart attacks, strokes and seizures. Ephedra is not recommended for weight loss. Safer approaches include calorie control, exercise and, when needed, prescription medications prescribed and monitored by a clinician.

What ephedra is

Ephedra (also called ma huang) is a plant that contains ephedrine alkaloids. In the late 1990s and early 2000s, supplements made from ephedra were widely marketed as weight-loss aids because they can increase heart rate and metabolic rate.

Why it fell out of favor

Although ephedra could produce short-term weight loss, regulators and researchers found serious safety problems. In the United States the Food and Drug Administration banned dietary supplements containing ephedrine alkaloids in 2004 after reports linked them to high blood pressure, heart attack, stroke and seizures. For that reason, ephedra is no longer a legal ingredient in over-the-counter dietary supplements in the U.S.

Note that the ban applied to dietary supplements; some ephedrine-containing drugs still exist under medical supervision for specific uses, but those are prescription products and not weight-loss supplements.

Health risks to know

Ephedra products raise cardiovascular strain. People with heart disease, high blood pressure, thyroid disorders, diabetes, or anxiety are at particular risk. Reported adverse effects included rapid heartbeat, elevated blood pressure, palpitations, and in rare cases heart attack or stroke. Because of these risks, mainstream medical guidance does not endorse ephedra for weight loss.

If you encounter ephedra products today

You may still see supplements or teas marketed online or sold in some countries that claim to contain ephedra or ephedrine. These products can be illegal or adulterated. If you are offered an ephedra product, avoid it and consult a healthcare professional. Report adverse events or suspicious products to your local regulatory authority.

Safer, evidence-based alternatives

Sustainable weight loss depends on diet and activity. Calorie control, increased physical activity, and behavior changes remain the foundation of safe weight management. When additional help is needed, clinicians can prescribe FDA-approved medications for chronic weight management; examples include orlistat, phentermine-containing combinations, and newer agents such as glucagon-like peptide-1 (GLP-1) receptor agonists (for example, semaglutide) or other prescription options. These medicines are used under medical supervision because they have their own benefits and risks.

Bottom line

Ephedra supplements were once popular but are no longer considered a safe or acceptable way to lose weight in the U.S. because the risks outweigh the modest weight-loss effects. If you are trying to lose weight, prioritize diet, exercise, and a consultation with a healthcare provider to discuss safe, evidence-based options.
