The Science

Cortisol is a steroid hormone that is released by the adrenal gland in response to stress or low blood glucose. It is responsible for controlling the body’s blood sugar levels, regulating metabolism, acting as an anti-inflammatory, influencing memory formation, controlling salt and water balance, influencing blood pressure and helping the development of a fetus in pregnant women.
