L-taurine is an amino sulfonic acid found abundantly in the brain and other tissues. Its use for supporting memory and brain function is primarily justified by scientific investigation, though the evidence in humans is still preliminary. Animal studies show that taurine plays important neuroprotective roles; it modulates neurotransmission, reduces neuroinflammation, and acts as an antioxidant. Some research in rodents suggests that taurine supplementation can improve memory and learning, especially in models of neurodegeneration or cognitive impairment. For example, taurine has been shown to enhance long-term potentiation (LTP)—a process essential for memory formation—and to protect neurons from glutamate-induced excitotoxicity.

In humans, clinical evidence is limited. Some small studies and reviews suggest potential benefits for cognitive function, particularly in elderly populations or those with neurodegenerative diseases, but these findings are not yet robust or widely replicated. Taurine is also a component of many energy drinks, which claim to boost mental alertness, but the cognitive effects of taurine alone (as opposed to in combination with caffeine and other ingredients) remain unclear.

Overall, while there are plausible biological mechanisms and promising animal data, clinical trials in humans are sparse. Therefore, the evidence for taurine’s effectiveness in supporting memory and brain function is rated as low to moderate (2/5), pending further research.
