ENP104: Hidden Ingredients in Supplements

October 15, 2025·11 min·1 clip

Guarana is a native Amazonian fruit used for centuries as a traditional medicine and stimulant, and in Brazil it's added to energy drinks to boost sexual function.

Host Aaron Lohr interviews endocrine specialist Dr. Meghana Padipati about a case where a 26-year-old man experienced severe hypoglycemia and elevated testosterone, which was eventually traced to hidden ingredients—specifically guarana—in a vitamin drink he was consuming. The episode explores the lack of FDA regulation for supplements, defines 'hidden ingredients,' and discusses the importance of reading labels for healthcare providers and patients.
