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.
Full review
Alpha BRAIN
Alpha BRAIN is widely used and professionally made, but it is hard to justify on the evidence: key doses are hidden in proprietary blends, the disclosed amounts are below studied levels, and trial results are modest. A single well-dosed ingredient such as L-theanine costs far less.
