What the evidence says

Mostly mechanism / observational

Most Uridine Monophosphate studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.

Most evidence is from medium-quality randomised trials published 2008–2017.

Across three RCTs, the uridine-monophosphate-containing medical food Souvenaid achieved small but clinically detectable memory effects in mild Alzheimer's, with no cognitive effect in mild-to-moderate disease.

Cummings J, Scheltens P, McKeith I, et al. · J Alzheimers Dis (2017)

Effect size ~0.20-0.21 on memory outcomes in mild AD (Souvenir I and II)
No effect on cognition in mild-to-moderate AD (S-Connect)
Effect is for the COMBINATION (uridine monophosphate + DHA + EPA + choline + phospholipids + B-vitamins), not standalone uridine

In memory-impaired rats, dietary uridine monophosphate or DHA improved water-maze performance, and combining the two enhanced it further while raising brain phospholipid levels.

Holguin S, Huang Y, Liu J, Wurtman R. · Behav Brain Res (2008)

Dietary UMP or gavaged DHA each improved hippocampal-dependent memory in impoverished rats (p < 0.05)
Co-administration of UMP + DHA further enhanced performance (p < 0.001)
UMP + DHA increased brain phosphatidylcholine and total phospholipid levels

Only the Fortasyn diet — fish oil plus uridine-monophosphate, choline, B-vitamins and cofactors — alleviated the spatial-learning deficit in Alzheimer-model mice.

Koivisto H, Grimm MO, Rothhaar TL, et al. · J Nutr Biochem (2014)

The Fortasyn combination (including uridine monophosphate) alleviated spatial-learning deficits where fish oil alone did not
Benefit was independent of brain amyloid reduction
Animal model only; tests the combination, not standalone uridine

Effect Size Analyses of Souvenaid in Patients with Alzheimer's Disease.

Chronic administration of DHA and UMP improves the impaired memory of environmentally impoverished rats.

Special lipid-based diets alleviate cognitive deficits in the APPswe/PS1dE9 transgenic mouse model of Alzheimer's disease independent of brain amyloid deposition.
