For anyone who’s ever bitten into a hot chili pepper and immediately reached for a glass of milk, capsaicin is the reason your mouth felt like it was on fire. This naturally occurring compound is what gives chili peppers their signature heat. But beyond the burn, capsaicin has been gaining attention for its remarkable health benefits, from pain relief to metabolic boosts. In this guide, we’ll dive deep into everything you need to know about capsaicin—what it is, how it works, its nutrition, benefits, side effects, supplements, and even who should and shouldn’t be taking it.
What is Capsaicin?
Capsaicin is an active compound found in chili peppers, particularly those from the Capsicum genus. It’s a colorless, odorless substance that binds to pain receptors in the mouth and other tissues, creating the sensation of heat or burning.
Interestingly, capsaicin evolved as a defense mechanism in peppers to discourage animals from eating them. But for humans, that fiery feeling has become something of a culinary and medicinal asset. Capsaicin is used both topically and orally, and is the primary ingredient in many over-the-counter pain relief creams, dietary supplements, and even weight-loss aids.
