There is nothing unsafe abput Uridine, in my opinion. In terms of unsafe reports, I think you would find way more for many other things. It's normally safe, with tendency to being very healthy.
An other example of "potentially unsafe": EGCG (green tea extract). It's super-healthy, but can potentially impact liver health negatively. Uridine is similar, with the difference that it's actually healthy for the liver in 90% of cases... (So what applies to EGCG all the time, without making it really unsafe at all, applies almost not at all to Uridine or is actually reversed.)
There is another one with a similar profile: Acetylcysteine is SUPER-healthy for the liver -except when you are recovering right now from alcohol-intake: therefore you have to take it before or when sober (not while drunk or detoxifying).
That's basically what you're dealing with, but I have no idea what else you might be referring to, and in the case of Uridine, this is nothing.
My two cents, as far as I'm concerned this should just be a side-note.
And to talk about something else: maybe consider Magnesium Threonate for NMDA-antagonism/upregulation and overall brain health. (There is a huge old thread speculating about Magnesium Threonate being different from any other Magnesium, and I can confirm it definitely is. Its psychological effect is about 500% stronger than Mg-Citrate.)
Also Zinc with Histidine (common combo) as a a NMDA antagonist and overall physical health.
