Sunshine Juice Ebisu has a popular juice “Heartbeat” jointly developed with marathon Japanese record holder Suguru Osako. Special juice "Heartbeat" made with a blend of beets, guarana, ginger, apples, carrots and lemons at the request of Osako. The ingredient called nitrate contained in beets softens blood vessels, improves blood flow in the body, and is said to be effective in relieving fatigue, and is used by many athletes overseas. Osako boosted beet juice with guarana to add caffeine, which he especially wanted before running. Natural caffeine that is slowly absorbed into the body is recommended. Whether you're running or not, if you're feeling tired, let the heartbeat of this special juice help you recover.
