BEN GREENFIELD SAYS
"Been using Four Sigmatic for awhile now. I’m impressed by the efficacies of their mushroom products."
"They have helped me to lower stress and improve my sports performance. The most impressive part is still the flavour, which is much better than the name “mushroom drink” initially implies."

“8 Best Instant Coffee Brands, Tested by Food Network Kitchen”
The coffee is full-bodied and smooth, with no mushroom flavor, and a packet has about half the caffeine of a regular cup, so you get all of the enjoyment with no jitters or crash.
