How caffeine works

Caffeine stimulates the metabolism, heart function and respiration. The consumption of caffeine narrows the blood vessels in the brain, thereby reducing fatigue. But caffeine is more than just a stimulant; researchers have discovered additional positive properties. Caffeine can also protect against adult-onset diabetes and cancer of the liver, and it promotes insulin sensitivity and controls hunger.

Another effect of caffeine ‒ although caffeine itself is not a hormone, it binds to the sexual hormone binding globulin (SHBG), which is an important factor for hormonal activity in metabolism. It can also have a positive effect on breast cancer and can contribute to reducing the risk of one form of skin cancer (basal cell carcinoma).
