The verdict

Alpha Brain uses proprietary "Focus" and "Flow" blends that legally hide each ingredient's dose. The amounts we can see fall below clinical thresholds, and the hidden ones can't be verified at all. You're paying $1.95/serving for underdosed nootropics — the same ingredients run about $0.48/serving in bulk.
