Antioxidant substances such as carotenoids (β-carotene, lycopene, lutein), flavonoids (quercetin, catechins), coenzyme Q10 and antioxidant vitamins (mainly E, C) contribute to improving memory. In particular, they prevent the action of harmful free radicals that are created daily from various causes. Moreover, stress, which is more intense especially during exam periods, is a source of free radicals, preventing the body’s cells from performing their functions properly. Fruit and vegetable juices are a good choice of antioxidants (it is best to make them yourself with fresh fruit). However, the alternative of ready-made juices (juices enriched with vitamins, dietary fiber and other ingredients have recently been on the market) are a nutritious solution.
