I was intrigued by the number and quality of ingredients in Flow. Most mental performance supplements are gimmicks, but the makers of Flow did their due diligence in selecting only the very best, research backed ingredients. As a chemist, this is important to me. While some individual ingredients might be found above or below the dosing used in some of the cited literature, the cumulative effect of the supplement is real, consistent, and as advertised. I enjoyed pairing it most with exercise, musical performance, reading, and writing. As long as it's an activity where a "flow state" is readily achievable, Flow will help get you there and keep you there for longer.
