How much caffeine is there in Mastermind?
Caffeine is not a main ingredient in Mastermind. However, note that traces are naturally present in guarana, black tea extract, and green tea extract. These contribute only 10-11 mg caffeine in each capsule, or roughly 60 mg caffeine in a daily serving of Mastermind (6 capsules). This equates to approximately 1 cup of black tea or less than a cup of coffee, and is below the limit of 400 mg caffeine per day, as suggested by Health Canada.
Studies have also shown that the jitteriness from caffeine intake is reduced with the presence of l-theanine, which is another active ingredient in Mastermind. If caffeine side effects are a concern, consider taking Mastermind with a meal.
