Its core roles and effects include: Neuroprotection and Antioxidant Properties: It possesses significant neuroprotective properties, capable of reducing the accumulation of reactive oxygen species (ROS) within brain cells, lowering oxidative stress and free radical damage to neurons, and preventing apoptosis. Cognitive and Memory Improvement: Studies show it helps support the function of brain tissue cells, positively impacting the enhancement of learning ability, memory, attention, and concentration. Sleep and Circadian Rhythm Regulation: It can act on the pineal gland and related neural pathways, helping to regulate the body's circadian rhythm (sleep-wake cycle), improve sleep quality, and alleviate stress-induced neurological disorders. Gene Expression and Cellular Repair: As a short peptide bioregulator, it can cross the blood-brain barrier and directly interact with intracellular DNA or related regulatory factors, promoting protein synthesis and the natural repair process of nerve cells.
