Focus Factor is dosed more like a multivitamin than a traditional nootropic. In the original formula, there’s only 640mg of nootropics altogether. However, Focus Factor still recommends taking this supplement with food, which is a dead giveaway that it could be hard on your digestive system. Be doubly sure to take it with food if you have a sensitive stomach. However, based on its ingredients and our testing, it’s not as intense (and, therefore, not as hard on your body) as many other nootropic supplements.
