When I first heard about NoStranger's mushroom coffee I instantly freaked out, but thankfully when I found out more about it like the benefits it comes with I gave it a try. What caught my attention is that the coffee beans were sourced from South America, so I knewww it had to be quality stuff because it reminded me of my coffee tour that I took in Costa Rica. Long story short, caffeine usually has a quick effect on me and makes me jittery but after drinking this coffee for a couple of months now, I have noticed it does not make me anxious or anything like that, and I love that because I can get through my day smoothly while still having COFFEE. Can't wait to order my next batch!
