If stress and belly fat are holding you back, the right supplements can make a difference. This guide highlights science-backed supplements to reduce cortisol and belly fat, helping you look leaner and feel calmer.
What Causes Cortisol-Driven Belly Fat?

Elevated cortisol—your stress hormone— drives fat storage in the abdomen. Chronic stress, poor sleep, and inflammation all contribute. Supplements to reduce cortisol and belly fat work by:
- Regulating the HPA (hypothalamic‑pituitary‑adrenal) axis
- Reducing inflammation
- Supporting adrenal and metabolic function
