Focus & Cognition
Three different routes people take toward sharper focus, so you can pick the one that fits rather than buy all three: a multi-herb Bacopa formula, a high-DHA omega-3 and single-ingredient creatine.
One of them, MetaFocus, carries a little caffeine; the other two do not. Sleep and nutrition still do most of the work for how clearly you think, so treat these as support rather than a substitute. Our Focus and Cognition guide covers what each ingredient has and has not been shown to do.
