Lysophosphatidylcholine (LPC) is a derivative of phosphatidylcholine, a major component of cell membranes. The interest in LPC for memory and brain function is largely due to its role as a transporter of choline and docosahexaenoic acid (DHA) across the blood-brain barrier, both of which are vital for neuronal health and cognitive processes. Preclinical studies, especially in rodent models, have shown that LPC can enhance the delivery of DHA to the brain, which is associated with improved synaptic function and neuroprotection. Some research also suggests that LPC may support neurogenesis and modulate inflammation in the central nervous system. However, direct clinical evidence in humans that LPC supplementation improves memory or brain function is limited. Most human studies focus on related compounds (such as citicoline or phosphatidylcholine), and the specific benefits of LPC itself in the context of cognitive enhancement have not been robustly demonstrated. Thus, while there is a mechanistic rationale and promising preclinical data, the evidence base is not yet strong enough to firmly support its use for treating or supporting memory and brain function in humans. Therefore, the evidence is rated as 2 out of 5, reflecting limited but emerging scientific support, primarily from animal and in vitro studies.
