Zazzee Extra Strength Citicoline (CDP-Choline) 500mg - Daily Choline Support for Focus and Memory (100 Vegan Capsules)
500 mg of citicoline in a plain two-ingredient capsule. The choline form we moved our own daily habit to once the Alpha-GPC safety data came out.
- 500 mg of citicoline per serving. Two capsules deliver the full clinically studied dose in one straightforward serving, not a fraction of it dressed up to look complete.
- CDP-choline, not Alpha-GPC. This is the choline source we default to for daily, ongoing use. The reasoning behind that choice is laid out honestly below, not just asserted.
- One active ingredient, three inert ones. The vegan capsule shell, a little rice powder, and a couple of standard flow agents. No proprietary blend, no filler stack to squint at.
- 100% vegan and free of the usual allergens. No gluten, wheat, corn, soy, milk, egg, fish, shellfish, or tree nut ingredients, and no artificial sweeteners or flavors either.
- Third-party tested, made in a GMP-certified U.S. facility. Independent verification behind the label claims, not just a promise printed on the bottle.
- A genuinely reasonable cost per serving. Around $0.70 a day at full price, less on subscription. We'd rather give you that number and let you compare it yourself than tell you it can't be beaten.

Choline was in John’s very first stack, and it has stayed in every version of it since. Most people fall short of it through diet alone, and a fair amount of everyday scattered focus and memory frustration traces back, at least in part, to not giving the acetylcholine system the raw material it needs. Citicoline is the choline source we default to now, after starting with Alpha-GPC years ago and moving away from it for daily use once the longer-term safety picture came into better focus. It’s the choline product we currently keep in our own cabinet.
Here’s the mechanism in plain terms. Citicoline splits into two useful pieces once it’s absorbed: choline itself, the direct precursor to acetylcholine, the neurotransmitter most closely tied to memory, learning, and sustained attention, and cytidine, which the body converts into uridine, a building block for the fatty membranes that make up brain cells.
That second piece is not something Alpha-GPC really offers, and it’s a meaningful part of why the two forms are not simply interchangeable. Worth being upfront about the evidence too: the strongest clinical results for citicoline come from older adults and people recovering from vascular or neurological injury, not healthy 25-year-olds.
A well-designed 2021 trial found 500 mg daily improved memory scores in adults aged 50 to 85 specifically. Evidence in younger, healthy adults exists but is thinner and more mixed. We think citicoline can help support daily focus and memory across a broader age range than that trial alone covers, but we’d rather point you to where the strongest data actually sits than let a label imply otherwise.
One correction worth making plainly, since it shows up in a lot of this category’s marketing: citicoline is not a more concentrated source of choline by weight than Alpha-GPC. It’s roughly the opposite, about 18% choline by weight here, versus roughly 40% for Alpha-GPC.
The advantage isn’t a bigger choline number. It’s the added cytidine and uridine component, plus the better long-term safety profile for daily use. That’s the advantage of Citicoline over Alpha-GPC.
This is also a generic form of citicoline rather than a trademarked, trial-branded raw material like Cognizin, which some competitors use. Citicoline is a single, well-defined molecule rather than a variable plant extract, so that distinction matters less here than it would for a botanical, but it’s still worth knowing before you buy.

Stack This With
Citicoline is a foundation piece, not a whole routine on its own. Here's where it fits alongside the other basics we carry, one from each adjacent category, chosen for the same reasons we picked this one.
Sports Research L-Theanine + Caffeine
for mornings when you want a calm, immediate lift layered on top of a slower-building choline foundation. Citicoline supports the raw material behind attention over the long run; theanine and caffeine change how the next few hours actually feel. No mechanism overlap between the two.
View product →Sports Research Magnesium L-Threonate
our other daily cognitive-adjacent basic, magnesium in a form with some evidence for reaching brain tissue more readily than other magnesium types. Different mineral, different pathway, genuinely complementary rather than redundant.
View product →Viva Naturals Triple-Strength Omega-3
the brain-lipid side of the equation citicoline doesn't cover by itself. DHA is a structural fat in neuronal membranes; citicoline's uridine component supports building those membranes in the first place. Two different, complementary parts of the same system.
View product →How to use them while stacking
- Morning, with food: citicoline (2 capsules) and omega-3 (2 softgels) together at breakfast is a simple daily anchor for both.
- Magnesium: most people we've worked with prefer it in the evening for the wind-down effect, though there's no strict requirement to time it that way for the cognitive angle specifically. Splitting the dose across the day works too.
- Theanine + caffeine, only if you want it: take it earlier in the day, morning or early afternoon, if you want an added, faster-acting lift. Skip it entirely on days you don't need a stimulant; citicoline, magnesium, and omega-3 don't depend on it being there.
- You don't need to start all four at once. If you're new to stacking, add one piece at a time so you can actually tell what each one is doing for you.

What citicoline actually is
Citicoline, also called CDP-choline (cytidine 5'-diphosphocholine), is a compound your body already produces in small amounts as part of normal cell metabolism. As a supplement it's typically manufactured through a fermentation-based process that yields the same molecule found naturally in the body, not an extract pulled from a plant or animal source.
How it works, in plain terms
Once absorbed, citicoline splits into two pieces your body puts to different use:
- Choline becomes the direct raw material for acetylcholine, the neurotransmitter most closely tied to memory formation, learning, and sustained attention. More available choline can help support that system doing what it's meant to do.
- Cytidine gets converted into uridine, which feeds into the Kennedy pathway, the cell's process for building the phospholipid membranes that make up cell walls, neurons included. This is the part Alpha-GPC, a different and more concentrated choline source, doesn't really provide.
Why citicoline over Alpha-GPC for daily use
We leaned on Alpha-GPC in the early days of building our own stacks, and we still think it has a place for an occasional, short-term focus push. But a large 2021 observational study tracking more than 12 million adults aged 50 and older found long-term Alpha-GPC users had a meaningfully higher rate of stroke over a 10-year period.
It's an observational study, not proof that Alpha-GPC directly caused those strokes, and the researchers were careful to say as much. It was still enough for us to move our own daily choline habit over to citicoline, which carries no comparable safety signal in the research, and to stop recommending Alpha-GPC for anything beyond occasional, short-term use.
What the evidence actually shows
The best-established research on citicoline comes from older adults and people recovering from strokes or other vascular brain injuries, where it has a genuinely long track record. A 2021 randomized controlled trial found that 500 mg of citicoline daily improved episodic memory scores specifically in adults between 50 and 85, which is the study most directly relevant to this product's dose.
Evidence in healthy adults on the younger end of that range is real but thinner and more mixed than the older-adult data. If you're in your twenties or thirties without any specific memory concerns, we'd rather tell you plainly that citicoline's effects for you may be more subtle, and slower to notice, than the older-adult research alone would suggest. This is a foundation-building ingredient, not a fast-acting one.
The choline gap most people don't think about
National dietary surveys have repeatedly found that most adults don't reach the Institute of Medicine's Adequate Intake level for choline through food alone. Egg yolks, liver, and certain fish are the main dietary sources, and a lot of typical diets are light on all three. A modest daily citicoline serving can help support closing part of that gap, not just function as a nootropic add-on layered on top of an already-sufficient diet.
Who it tends to suit
- Anyone building a long-term, daily cognitive foundation rather than chasing an acute effect.
- People moving away from Alpha-GPC for daily use who still want a choline source in their stack.
- Adults 40 and up, where the existing evidence base is deepest.
- Anyone whose diet is genuinely light on eggs, liver, and fish, the main dietary choline sources.
Who it is probably not for
- Anyone expecting an immediate, caffeine-like effect. Citicoline builds gradually; there's no acute kick to notice.
- Anyone already taking Alpha-GPC or another choline source daily. Stacking multiple choline sources has no real evidence of added benefit and mostly just raises the odds of mild cholinergic side effects like headache or stomach upset.
- Anyone on Parkinson's medication (levodopa) or another drug acting on the cholinergic system, without talking to their doctor first (more under Ingredients).
How To Use
Take 2 capsules daily, ideally with food. That's the full studied serving, providing 500 mg of citicoline.
Morning or early afternoon is a sensible default. Some people notice mild alertness from citicoline, a much gentler version of what caffeine does, and taking it too late in the day can occasionally show up as trouble winding down. This isn't universal, but it's common enough to flag.
Give it real time before judging it. This isn't a same-day ingredient. The research behind it generally used weeks of consistent daily use before measuring any outcomes. Give it at least 4 to 6 weeks of daily use before deciding whether it's doing anything for you.
How to dose it
- 2 capsules (500 mg) is the full studied serving behind most of the research on this ingredient. There's no evidence that more improves outcomes further.
- Some people split it, 1 capsule in the morning and 1 at midday, though there's no requirement to do it that way.
How to stack it
- Fits cleanly alongside our magnesium, omega-3, and theanine + caffeine basics, no mechanism overlap (see Stack This With above).
- Don't add Alpha-GPC or another choline source on top of this one. There's no evidence of added benefit, only added side-effect risk.
- No cycling required. This is meant to be a steady, ongoing daily foundation, not something you take breaks from.
What to avoid
- Taking it late at night if you notice it affects your sleep.
- Combining it with Parkinson's medication (levodopa) without your doctor's input, since citicoline can enhance levodopa's effects.
- Assuming faster is better. Two capsules once a day is the studied amount; there's no data suggesting a bigger dose works faster or works better.
Third Party Lab Testing
- Third-party tested for purity and potency, per the manufacturer's label claim, independent verification rather than an in-house promise alone.
- Manufactured in the USA in a GMP-certified facility (Good Manufacturing Practice), the standard quality-system certification for supplement production.
- Non-GMO and vegan, stated plainly on the label, with no animal-derived ingredients anywhere in the capsule.
- A generic, non-trademarked form of citicoline. Worth being direct about: this isn't a branded ingredient like Cognizin, which carries its own dedicated research and documentation trail. Citicoline is a single, well-characterized molecule rather than a variable botanical extract, so the practical difference is smaller here than it would be elsewhere, but it's a distinction we'd rather flag than gloss over.
As with any supplement, the strongest form of proof is a batch-specific Certificate of Analysis (COA) tied to the lot number printed on your bottle. If verifying a specific batch matters to you, note the lot number and request the COA from the manufacturer. If a brand can't produce one, that tells you something.

Customer Reviews
I was dealing with pretty bad brain fog for a while and started looking into what seemed to help the most. Oddly enough, I realized I always felt sharper after eating eggs or having a 5-hour Energy. After doing some digging, I found that citicoline was something they had in common, so I gave this supplement a try. I'm really glad I did because it made a noticeable difference. My mind feels clear again, I'm thinking faster, and I honestly feel like I'm back to normal. This has worked better than I expected.
I had been using some bulk citicoline that a friend gave me, so I already knew how well it worked for me. Once I ran out, I decided to try this brand because it claimed to be high quality without costing a fortune. Thankfully, it delivers. I still take it every morning along with my coffee, and I've noticed I don't lose my train of thought or struggle to find the right words nearly as often. It's become part of my daily routine, and I have no plans to stop taking it.
I spent quite a bit of time comparing different choline supplements before buying this. I looked into Alpha GPC, CDP Choline, choline bitartrate, and a bunch of brands. A lot of them either had unnecessary fillers, gelatin capsules, questionable ingredients, or were just overpriced. This one stood out because it's clean, uses veggie capsules, and doesn't load up on junk. After a couple of weeks, I noticed better focus and much clearer thinking than I ever got from similar supplements. The value is also hard to beat since you get more capsules for the price than most competing brands.
