Problems with memory and concentration can be caused by many different factors, such as stress and fatigue, inadequate diet, noise, some diseases or aging of the body. Preparations supporting the efficiency of the mind can be intended both for young people, e.g. during education, as well as for older people who have cognitive impairment with age. Ingredients that support memory and concentration include, m.in, ashwagandha, ginkgo biloba, omega-3 fatty acids, lecithin, cytocolline, Rhodiola rosea or ginseng.
