Thanks to brands like Four Sigmatic selling pre-made mushroom coffee mixes, this has quickly become a lasting trend.  All else equal, mushroom coffee is healthier than normal coffee for most people. Depending on the mushrooms used, it contains a plethora of powerful health-benefiting bioactive substances. Sadly, however, all else is rarely equal. Some brands use low-quality coffee beans and the addition of mushrooms helps mask the taste of inferior coffee.
