Appropriate amount of caffeine can also reduce muscle fatigue and promote digestive juice secretion. Because it promotes kidney function, it is diuretic and helps the body to expel excess sodium ions from the body. Caffeine accelerates metabolism, promotes digestion and improves constipation. From the point of view of these functions, it can also help improve the roughness of the skin.
