(CNN) — If you’ve spent time on TikTok or Instagram lately, chances are the “cortisol cocktail” trending as the latest wellness hack has appeared in your feed. This colorful, nonalcoholic drink typically contains a mix of coconut water, citrus juice and certain salts. Also called an “adrenal cocktail,” it has amassed millions of views, with influencers claiming it can lower stress hormones, boost energy and balance your body’s adrenal function.

Almost half of Americans (49%) report frequent bouts of stress, and the number of people in the United States who are feeling stressed has been rising for the past two decades, according to a 2024 Gallup survey. In these uncertain times, a stress-relieving tonic feels just right as a soothing balm, but does it actually live up to the health claims?

What is cortisol and its relationship to stress? What nutrients are in these drinks and how are they purported to influence cortisol? Do they work? Who should be wary of trying this concoction?

To guide us through these questions, I spoke with CNN wellness expert Dr. Leana Wen. Wen is an emergency physician and adjunct associate professor at George Washington University. She previously was Baltimore’s health commissioner.
