What verified buyers say.
“I find it helps with memory and I appreciate the simple ingredients, without additives.”
“I have only been taking this supplement for two weeks - no side effects and better able to focus.”
“I feel great when I take Eudopa. I don't always remember to take it everyday, but on days that I do, I feel energetic and a mental clarity that helps with my work.”
“Someone finally did it — a focus and memory product that doesn't rely on stimulants. eudopa™ uses simple, science-backed ingredients.”
Three ingredients.
Nothing hidden.
Citicoline
Why it’s here: the raw-material supply for the neurotransmitters behind focus and memory.*
How it works
Provides choline and cytidine — building blocks that support neurotransmitter production and healthy cell membrane structure.*
Your brain uses choline to produce acetylcholine — a neurotransmitter involved in focus, learning, and memory. Citicoline provides both choline and cytidine, which your body converts to uridine — a nutrient involved in cell membrane synthesis.*
This is the supply side of the formula. Citicoline provides the raw materials your brain uses to build and maintain the membranes where communication between neurons takes place.*
Wild Blueberry
Why it’s here: antioxidant support for the cell membranes the other two ingredients build and maintain.*
How it works
The deep purple pigment of wild blueberries comes from anthocyanins — plant compounds studied for their antioxidant activity.*
Anthocyanins are the compounds that give blueberries their deep colour. They're studied for their antioxidant activity and their role as part of an anthocyanin-rich diet.*
Brain cell membranes — the ones citicoline builds and phosphatidylserine supports — are lipid-rich environments where oxidative processes naturally occur. Blueberry anthocyanins complement the formula by contributing antioxidant activity alongside citicoline and PS.*
Phosphatidylserine
Why it’s here: keeps cell membranes fluid — the surface where brain-cell communication actually happens.*
How it works
A structural phospholipid that helps maintain the fluidity of brain cell membranes.*
This dose sits at the lower end of the 100–300 mg/day range studied in systematic reviews of PS supplementation in older adults. PS is a phospholipid abundant in your brain's cell membranes, playing a structural role in keeping those membranes fluid and functional — which matters for how signals pass between neurons.*
Citicoline supplies the building blocks. Blueberry contributes antioxidant activity. PS supports the structural integrity of the membranes — the surface where communication happens.*
How one supplement can support so many things.
It starts with the foundation.
If someone told you one thing could make your apps load faster, fix your video call lag, and make all your streaming work better — you'd probably be skeptical. But if that thing was just a faster internet connection, it makes perfect sense.
Your brain works on the same principle. Focus, memory, clarity under pressure — these aren't separate systems with separate fixes. They share a single foundation: how well your brain cells communicate with each other. eudopa™ works at that layer — research-backed nutrients chosen to support healthy cellular communication.
The routine.
- Two capsules, once a day — with breakfast, or alongside your morning coffee.
- No cycling, no loading. Just consistency.
- Most published research on these ingredients runs 6–12 weeks of daily use. Give it 60 days — the money-back guarantee covers every one of them.

What does “100 mg active PS” mean — and why is it on the label?
The dose that actually matters
Phosphatidylserine is sold to manufacturers as an extract — typically 50%, 70%, or higher concentrations of PS suspended in carrier material. Most brands list the total weight of the extract on their label (e.g. “200 mg phosphatidylserine”) without disclosing the percentage of active PS inside. That's how two different supplements can both claim “200 mg PS” and deliver anywhere from 50 mg to 200 mg of the actual active compound.
eudopa™ uses 200 mg of a 50% soy-derived PS extract, which delivers 100 mg of active phosphatidylserine — the dose used in the published research we cite. We list the active amount on our label because it's the only number that matters for the effect.
Do I still need to eat blueberries if I take eudopa?
Yes — whole-food blueberries complement the formula
Yes — and we'd encourage you to. The blueberry extract in eudopa™ provides a supportive amount of anthocyanins (around 22 mg per dose) that works alongside citicoline and phosphatidylserine as part of the formula. It's a meaningful contribution, but it's not a substitute for the whole-food dose of anthocyanins you'd get from actually eating blueberries regularly.
Published studies on blueberries and cognition have generally used anthocyanin intakes several times higher than what any two-capsule serving can reasonably contain. We designed eudopa™ around a two-capsule daily serving because that's the limit most people will take consistently, and the capsule size we use is the largest most people will swallow without complaint. Between 500 mg of citicoline, 200 mg of soy-derived PS extract (delivering 100 mg active PS), and 250 mg of blueberry extract, we're already close to the physical limit of what two capsules can hold. Blueberry extract contributes what it can within that constraint. A cup of fresh or frozen wild blueberries a few times a week fills in the rest — and tastes better than any capsule.*
