Pre-built nootropic stacks ranked
#2: Onnit Alpha Brain ($34.95/45 servings, $1.55/day)

#3: NooCube Brain Productivity ($59.99/30 servings, $2.00/day)
Bacopa 250mg, L-Theanine 100mg, L-Tyrosine 250mg, choline bitartrate. Transparent dosing on most ingredients. No published study on finished product. Solid middle ground. Score: 7.2/10.
