Our verdicts
Focus Mushroom Ground Coffee (formerly Think)
Focus is the easiest mushroom coffee to recommend if you simply want a good organic dark roast: it tastes like regular coffee and discloses its mushroom doses. Just don't expect the lion's mane or chaga to do much at 250 mg each, because the caffeine is doing the heavy lifting.

Energy & Focus Gum
Energy & Focus Gum is one of the few products in this category whose formula matches the evidence: a modest caffeine dose paired with L-theanine, clearly labeled. It won't transform your brain, but as a convenient, controllable caffeine hit it does what it says, provided the sugar alcohols and taste agree with you.
