There are tens of thousands of different dietary supplements sold in the USA, with more added each year, so it is not possible for us to make any general recommendations about adding Qualia Mind® to an existing supplement regimen.
We do not recommend giving Qualia Mind® to children or teenagers, because (1) some of the ingredients have only been studied in adults, and (2) a 6 capsule suggested serving size contains 100 mg of caffeine, which when added to the amount of caffeine many teens consume in sodas, coffee drinks, energy drinks, etc., would place them above the amount recommended by doctors (The American Academy of Pediatrics suggests limiting caffeine intake to 100 mg in adolescents ages 12 to 18 years old and has not designated a safe threshold for caffeine in children 11 years old and younger).*
Most ingredients have many different forms of varying quality and potency. In every case, we chose the absolute highest grade form of each ingredient for Qualia.
Several ingredients in Qualia Mind®—Rhodiola, Ginkgo, PQQ, Lutein, Phosphatidylserine, and Nutricog®, as examples—can be thought of as more akin to the tortoise than the hare from Aesop’s fable (i.e., “slow and steady wins the race”).
