For the last month I have been taking uridine and alpha-GPC every morning and the results have been remarkably consistent. I take 250mg of uridine monophosphate from Jarrow Formulas and 300mg of alpha-GPC from NOW.
The stack reliably puts me into a focused and calm state with an added mild mood boost. I have struggled with mood swings, anxiety, depression, and memory problems for years, and this combination has pretty much resolved all of those symptoms.
I have tried a massive number of nootropics over the past six years, probably spending close to a thousand dollars in total, and this simple two-supplement stack gives me the most reliable results of anything I have found.
One important note: dosing matters more than you might expect. If I take more than one capsule of each, I start getting signs of what feels like excessive choline or dopamine. Jittery, slightly anxious, and overstimulated. The sweet spot for me is definitely one capsule of each.
I highly recommend this as a beginner stack for somebody looking to explore what nootropics can actually do. It is affordable, well-tolerated, and the effects are noticeable without being overwhelming.
