Uridine Monophosphate

Nootropicoral · inferred

Pyrimidine nucleotide involved in RNA synthesis and phospholipid membrane production. Synergistic with DHA and choline for synaptogenesis. Converted to UTP/CTP in the brain, promoting phosphatidylcholine synthesis. Short half-life (~2-2.5h) means plasma levels return to baseline by 8 hours. Also enhances dopamine release.

Projected serum levels — 250 mg, once daily

Research behind this entry

  1. Dietary uridine enhances the improvement in learning and memory produced by administering DHA to gerbils Holguin S et al. · FASEB Journal, 2008 DOI

    Co-administration of uridine with DHA and choline synergistically improved performance on radial arm, T-maze, and Y-maze tests beyond DHA alone, demonstrating synaptogenic synergy.

  2. Dietary uridine-5'-monophosphate supplementation increases potassium-evoked dopamine release and promotes neurite outgrowth in aged rats Wang L et al. · Journal of Molecular Neuroscience, 2005 DOI

    UMP supplementation in aged rats significantly increased striatal dopamine release and enhanced NGF-induced neurite outgrowth, supporting its role in synaptic plasticity and dopaminergic function.

  3. Open-label uridine for treatment of depressed adolescents with bipolar disorder Kondo DG et al. · Journal of Child and Adolescent Psychopharmacology, 2011 DOI

    Pilot open-label trial in 7 depressed bipolar adolescents showed uridine (500 mg BID for 6 weeks) significantly improved depressive symptoms as measured by CDRS-R scores.
