Triacetyluridine (TAU) is a prodrug of uridine, a naturally occurring nucleoside involved in numerous cellular processes, including RNA synthesis. Scientific research has investigated the role of uridine and its derivatives in supporting brain function and neurotransmitter systems. Several preclinical and clinical studies have demonstrated that uridine can enhance synaptic membrane formation, increase levels of certain neurotransmitters (such as dopamine), and support neuroplasticity. Specifically, uridine is a precursor for the synthesis of phosphatidylcholine, a key phospholipid in neuronal membranes, which is critical for synapse formation and function.

In animal models, oral administration of uridine or triacetyluridine has been shown to increase brain uridine levels and positively impact neurotransmitter systems, including supporting dopamine release and receptor sensitivity. Some small clinical studies and case reports have explored the use of triacetyluridine as an adjunct in psychiatric and neurological conditions, such as bipolar disorder and depression, with some positive findings, though large-scale, well-controlled trials are lacking. Therefore, while there is a plausible scientific rationale and some supportive evidence for the use of triacetyluridine to support specific neurotransmitter systems, particularly in the context of synaptic function and neuroplasticity, the overall level of evidence is moderate and still emerging.
