Alpha Brain is Onnit's flagship nootropic supplement designed to support cognitive functions like memory, mental clarity, and focus—all without any caffeine.
The formula includes ingredients like L-Tyrosine (for stress-related focus), L-Theanine (for calm alertness), and Oat Straw Extract to fuel brain activity. It's designed to help you achieve "flow state"—that mental zone where you're completely dialed in and productive.
Popular with everyone from busy professionals to Joe Rogan podcast fans, Alpha Brain works best when taken consistently over time. Some people notice effects quickly, others need a few weeks to feel the difference.
Not a magic pill, but genuinely helpful if you're looking to support mental performance without adding more caffeine to your life. Available in capsule or instant drink mix form.
