I love Ganoderma coffee. I buy the 2 in 1 box, and enjoy every cup. I don't really care for regular coffee anymore after drinking the Ganoderma coffee. Besides the great flavor, I feel better when I drink it. There are no jittery side effects or energy drops from the caffeine, and yet, I feel like I have more energy and overall better health. My skin is also much more clear, and my stomach feels better when I drink the Ganoderma on a regular basis.
