I have been taking Wonder Coffee for a couple of months now and have definitely noticed a difference in my energy level and my ability to focus throughout the day.
As great as that is, it wouldn't really matter if it didn't taste good.
I have tried several other mushroom coffees and I just couldn't keep up with them because of the taste.
Sometimes I drink Wonder Coffee with my regular coffee in the morning, sometimes I drink it by itself.... Either way, it is enjoyable.
