Why it works
Renergy® combines the clinical nootropic COGNIZIN® with Rhodiola rosea, ALA and Resveratrol to activate the AMPK and SIRT1 pathways of mitochondrial metabolism. Sustained release guarana with apigenin modulates stimulation without overactivating the nervous system. Real cellular energy, without the collapse of conventional stimulants.

The most important things about Renergy®
Take 3 capsules a day, preferably in the morning or before the most physically or mentally demanding day. The combination of sustained release guarana with apigenin is designed for progressive activation without sudden peaks or subsequent decline.
To avoid interference with sleep, it is recommended not to take Renergy® after 5 p.m. Consistency is key: the effects on sustained energy and cognitive endurance accumulate and consolidate with continued use.
Renergy® is formulated for people who need to perform at their best throughout the day and have found that conventional stimulants are no longer enough. You could especially benefit if you identify with any of these situations:
- Low performance in the middle of the afternoon: maximum demand at the time when the body no longer has fuel.
- Your brain does not start at the pace you demand: body and mind do not go at the same pace and that has a cost.
- Stimulating yourself no longer works: coffee or energy drinks activate you for a moment and leave you worse than
- You lose focus when you need it most: concentration slips just at critical moments.
- Sustained high mental load: intense intellectual work, creativity under pressure or continuous decision making.
- High demanding physical load: performance training or physical activity that requires real energy, not artificial stimulation.
Food supplements should not be used as a substitute for a varied and balanced diet or of a healthy lifestyle. If you have questions, you can contact our team at [email protected]
Results may vary depending on the person, although the key is consistency. Renergy® acts on three simultaneous fronts — nootropic activation, mitochondrial efficiency and adaptogenic resistance — and its effect accumulates over time.
First week
Sustained release guarana and L-tyrosine offer mental activation without sudden peaks from the first days. COGNIZIN® increases the availability of brain acetylcholine for greater clarity and processing speed. Energy is perceived as more stable and the morning burst improves immediately.
Three to four weeks
Rhodiola rosea and ALA improve mitochondrial efficiency and resistance to sustained physical and mental stress. The mid-afternoon slump is significantly reduced and recovery after exertion is noticeably faster. Dopamine and norepinephrine are maintained at levels that sustain focus and motivation.
First month
COGNIZIN® together with active B vitamins and selenium optimize neuronal function in a sustained manner. Concentration and mood remain stable throughout the day, without the need for additional stimulants to reach the end of the day.
Three months onwards
With continued use, energy stability and cognitive resilience are consolidated. The body produces energy more efficiently from within each cell and performance is sustained naturally without relying on external triggers.
Yes. Renergy® is suitable for:
- Vegans
- Celiacs
- Lactose intolerant
- Gluten-free diets
Each daily dose of Renergy® (2 capsules) combines proprietary nootropics, mitochondrial activators and precision adaptogens to cover all fronts of energetic and cognitive performance. All active ingredients are present in doses with clinical support, not in symbolic quantities.
Its formula includes:
- COGNIZIN®: registered citicoline that increases the production of acetylcholine and improves the availability of neuronal energy for focus and working memory
- Sustained release guarana: natural source of progressive release caffeine that prevents sudden peaks and subsequent collapse energetic
- Apigenin and chamomile: modulate the stimulation of guarana for a state of calm alertness without overactivation of the nervous system
- L-tyrosine: direct precursor of dopamine and norepinephrine, replenishes the neurotransmitters of focus and motivation that sustained stress consumes
- Rhodiola rosea: adaptogen that modulates the HPA axis to improve resistance to physical stress and sustained mental health without depleting neurotransmitters
- ALA and Resveratrol: activate AMPK and SIRT1 to optimize mitochondrial metabolism and neuronal ATP production
- Active vitamins B5 and B12: contribute to normal energy metabolism and the functioning of the nervous system with solid EFSA claims
- Selenium: antioxidant that protects cells from oxidative stress generated by effort intense cognitive and physical

Frequently asked questions
Because the fatigue you describe isn't from lack of stimulation: it's from system exhaustion. Caffeine temporarily activates the nervous system, but it doesn't repair mitochondrial energy production, doesn't regulate the response to accumulated stress, and doesn't replenish the neurotransmitters that sustain mental focus. When those systems are below their optimal level, no stimulant can recover them. Sustained cognitive performance has three simultaneous origins: neurotransmitter availability — dopamine, acetylcholine, noradrenaline —, mitochondrial efficiency to produce neuronal ATP, and stress resistance that exhausts both systems. A single stimulant attacks the first front and leaves the other two unresolved. Performing better isn't a slogan. It's the goal. And RENERGY® is the nutritional architecture we work on every day to bring you closer to it.
