Psychobiotic Lactobacillus plantarumJYLP-326

   Tingtao Chen's team: Lactobacillus plantarum JYLP-326, a psychotropic probiotic, can alleviate test anxiety, depression and insomnia in university students by regulating the intestinal flora and its metabolic profile.

    Test anxiety is an emotional state of nervousness and anxiety displayed by candidates before and during a test. Test anxiety can cause physical and mental sequential adverse reactions, such as dizziness and sweating, rapid heartbeat, slow reaction time, nervousness and lack of concentration, which can seriously harm students' physical and mental health and lives. Therefore, how to effectively respond to or alleviate test anxiety has become a social concern of great significance. Studies have shown that dysbiosis of intestinal flora and alteration of its metabolic profile are involved in the onset and development of a variety of mood disorders (e.g., anxiety and depression, etc.), implying that intervening in or manipulating intestinal flora and its metabolism in some way may provide a new idea for the prevention and alleviation of test anxiety. 

       Probiotics are "active microorganisms that, when consumed in sufficient amounts, produce health benefits for the host" (defined by the World Health Organisation), which have both nutritional and therapeutic properties; and with the deepening of scientific research, the relationship between probiotics and gut flora and their role in maintaining the health of the host has become more and more important. and their functional role in maintaining the host's life and health have been gradually resolved with the deepening of scientific research.
