Both options occur in practice, and the choice depends on what your working rhythm looks like. If the intellectual load is spread evenly — studying, a busy work schedule, regular deadlines — it is convenient to take the supplement as a course of 1 serving (3 capsules) a day, for no longer than 4 weeks in a row. If the load comes in waves, it is chosen occasionally: before an exam, an important project or a long drive.
The formula combines fast-acting components and those whose effect builds up gradually. Guarana and L-theanine work relatively quickly: guarana, as a source of caffeine, helps you get into your tasks, and L-theanine balances this effect without causing excessive excitement. Bacopa monnieri and the adaptogens — ashwagandha, rhodiola rosea and ginseng — are traditionally used in courses, since their effect appears with regular use.
It is important to bear in mind that, because of the caffeine content (via the guarana extract), the product is best taken in the first half of the day so as not to affect the quality of your sleep. Sleep is one of the key factors in mental performance, and the supplement does not replace it.
If you are sensitive to caffeine or take other products containing it (coffee, tea, pre-workout complexes), consider your total intake. The product is intended for adults only and is not used in children, pregnant or breastfeeding women; in case of chronic diseases or when taking medicines, consult a specialist first. It may contain traces of milk (including lactose), soy, peanuts, nuts, sesame, oats, eggs, fish and crustaceans.
