What’s inside
Plus the vegan capsule, and nothing else. No proprietary blends, no caffeine.
How to use
Who’s it for
Those who find it especially useful:•Students and working professionals: those who demand a lot from their brain through long days of studying, work and decision-making, and want daily support for cognitive health and brain function.•Health-conscious adults: those who want to look after their brain the same way they already look after their heart, as one simple habit they can keep for the decades ahead.Do not use if you are pregnant or breastfeeding. Consult a health care practitioner prior to use if you are taking blood thinners. Ask a health care practitioner before use if you are taking dopaminergic or cholinergic drugs. If you are suffering from hypertonia of the parasympathetic nervous system, consult a health care practitioner prior to use. Occasional restlessness and excitability, digestive intolerance, and headache have been known to occur.

Brain health is for everyone.
Made in CanadaYour brain has many different abilities. But they all have something in common.
Focus. Memory. Learning. Problem-solving. Self-control.
These are just a few of the many cognitive abilities your brain gives you. They may do very different things, but underneath, they all depend on the same foundation: networks of brain cells functioning and communicating together.
Brain cells function and communicate
Brain cells send and receive signals from one another. This communication allows information to move between cells throughout the brain, and it depends on each cell doing its own job well.
Those cells form networks
Brain cells work together in connected networks, with different networks supporting different cognitive functions.
Those networks make cognitive abilities possible
The coordinated activity of these networks gives rise to abilities like focus, memory, learning, problem-solving and self-control.
That’s the foundation eudopa was designed around.
Instead of designing eudopa around one cognitive ability like memory or focus, its three ingredients were selected to support different processes involved in brain-cell function and communication that many cognitive abilities depend on.
3 clinically studied ingredients. No proprietary blends.
Memory16–19. Recall and memory performance.
Cognitive Performance18–21. Performance across selected memory and executive-function tasks.
Vascular Function16,19,21,22. Blood-flow and endothelial-function measures.
At NeuroVesa, the brain is our only focus.
We don’t make protein powders, beauty supplements, or joint formulas. We specialize in the brain, and only the brain.
That focus allows us to go deeper into the science, be more selective about what we formulate, and hold every product we create to a higher standard.
eudopa is the first product we built around that philosophy.
“I have only been taking this supplement for two weeks - no side effects and better able to focus.”
Wendy D.Verified buyer
“Great product. Mental clarity and energy was astounding. Would absolutely recommend this product.”
DylanVerified buyer
“I’ve been using eudopa for about two years- I’ve seen a great increase in focus, memory and mood.”
Christine S.Verified buyer
“I’ve found eudopa helps me feel noticeably more focused without relying on stimulants for short-term energy. What interested me about the formula is that its ingredients support processes involved in brain-cell function and communication, which are important to many aspects of cognitive performance.”

NeuroVesa brand partnerEvery batch of eudopa is independently tested for quality, purity, and identity.
Every batch is tested two ways: the finished product is screened for contaminants, and an independent laboratory verifies the active ingredients are exactly what the label says. We publish both reports in full below.
The best investment you can make is in your brain.
Frequently asked questions.
What makes eudopa different from other brain supplements?
eudopa is the only brain supplement that combines citicoline, phosphatidylserine, and wild blueberry extract. Each ingredient was selected to support a different process involved in how brain cells function and communicate.
Essentially all cognitive abilities, from focus and memory to learning, problem-solving, and creativity, depend on brain cells working together. Instead of focusing on one ability alone, eudopa was designed to support the foundation they all share.
How long does it take to notice benefits?
The research behind eudopa’s ingredients reflects outcomes measured with consistent daily use. eudopa is designed to work gradually over time, not produce overnight changes. Taking it consistently each day, ideally around the same time, is the most reliable way to experience its full benefits.
That said, some people may begin noticing changes within 1–2 weeks of consistent use, with more noticeable effects potentially developing over 4–6 weeks. Results vary from person to person.
How and when should I take eudopa?
Adults should take two capsules daily, preferably in the morning. eudopa can be taken with or without food, although taking it with a meal may be more comfortable if you have a sensitive stomach.
You can take both capsules together or split the serving by taking one in the morning and one in the early afternoon. eudopa is not a stimulant, but some people may feel more alert or focused after taking it, so we recommend avoiding it close to bedtime.
Is eudopa vegan, and does it contain any allergens?
Yes. eudopa is made without animal-derived ingredients and is suitable for vegans.
It does contain soy because its phosphatidylserine is derived from soy lecithin. Anyone with a soy allergy should avoid taking eudopa.
Can I take eudopa with caffeine?
Yes, eudopa is caffeine-free and contains no stimulants.
Can I take eudopa alongside prescription medications?
We recommend consulting your healthcare provider before adding any supplement to your routine if you are currently taking prescription medications. This is particularly important if you:
- Take blood thinners
- Take dopaminergic or cholinergic drugs
- Have hypertonia of the parasympathetic nervous system
Your healthcare provider is the right resource for guidance specific to your health situation.
Does eudopa have any side effects?
The ingredients in eudopa are generally well tolerated when taken as directed. However, some people may experience side effects such as headaches or digestive discomfort.
Taking eudopa with food may help if you have a sensitive stomach. If side effects persist or you experience an allergic reaction, stop use and consult your healthcare provider.
What if eudopa isn’t right for me?
eudopa is backed by our 60-day money-back guarantee. This gives you time to take it consistently and decide whether it is right for you.
If you are not satisfied, email us at support@neurovesa.com within 60 days of your purchase and we will issue a refund. No questions asked, and no need to send the bottle back.
