Concentration

Concentration is the ability to maintain attention on a single subject or task for an extended period. The capacity for concentration is influenced by the health of the nervous system. When the transmission of stimuli is functioning well, it becomes easier to stay focused, to store information in memory, and to recall it when necessary.

However, concentration can be adversely affected by various factors, such as lack of sleep, insufficient physical activity, and unhealthy nutrition. Conversely, concentration can be enhanced by ensuring a good night's sleep, engaging in regular exercise (which improves circulation and thus the blood flow to the brain), and consuming a diet rich in essential nutrients.

The following nutrients are known to play a significant role in brain function:

Magnesium, vitamin C, vitamin B1 (thiamine), B3 (niacin), B6 (pyridoxine), biotin, folic acid, and B12.

A varied diet provides all these nutrients. However, in some cases, supplementation in the form of a multivitamin may be desirable. For example, children and teenagers can benefit from the Multi for Children or Teenagers.

The omega-3 fatty acid DHA (found in eggs, fish, krill, and certain algae) is also important for maintaining normal brain function. In our bodies, DHA is primarily found in the brain, the nervous system, and the retina of the eye. For children, DHA is available as flavoured liquid oil, and in the form of chewable capsules. The health claim "contributes to the maintenance of normal brain function" is only permitted by the EFSA for supplements that provide at least 250 mg of DHA per daily dosage.

Other Aids

Caffeine is not an essential nutrient, but it does have the ability to temporarily enhance concentration. Well-known sources of caffeine include coffee, tea, guarana, yerba mate, and gotu kola.

Lecithin, found in egg yolks, sunflower seeds, and soybeans, contains the components phosphatidylcholine and phosphatidylserine. These phospholipids play an important role in the functioning of our brains, but our bodies typically produce enough lecithin on their own and also receive ample amounts from food. Lecithin as a dietary supplement is particularly recommended for seniors. For younger individuals, taking additional lecithin is of little benefit.

Additionally, there are various herbs that can be used to support blood circulation (for example, Ginkgo biloba). Good blood circulation promotes an adequate oxygen supply to the brain, resulting in improved functioning.

Calming herbs can also sometimes help, especially since excessive tension can disrupt sleep. Moreover, stress ("stage fright") during situations such as exams can hinder cognitive abilities. Herbs like valerian can be used for non-sedative relaxation.
