Caffeine smart*: designed for your study sessions
Caffeine smart* from EssentialSeries is a plant-based capsule dietary supplement that combines natural anhydrous caffeine from coffee beans, L-theanine, pantothenic acid, vitamin B6 and zinc.
Caffeine helps to increase alertness and improve concentration, two aspects especially interesting during exam periods, exam prep, demanding projects or long mental-work days.
Its name also reflects the presence of pantothenic acid, which contributes to normal intellectual performance. Vitamin B6 helps to reduce tiredness and fatigue, while zinc helps to support normal cognitive function.
CaffXtend™: the difference is in how it releases
Not all caffeine follows the same release pattern. For this formula we chose CaffXtend™, a branded raw material, made with natural caffeine microencapsulated in a matrix designed to release gradually over up to 12 hours.
Compared to immediate-release caffeine, which quickly reaches its maximum concentration, CaffXtend™ offers a more progressive profile. In a comparative study conducted with healthy volunteers, prolonged-release caffeine took more than four times longer to reach its maximum blood concentration, keeping total caffeine exposure similar (Thanawala et al., 2024).
When the study session stretches, both caffeine and how it’s released matter.
This pattern makes CaffXtend™ especially suitable for routines requiring continuity: full mornings of study, prep of extensive syllabi, classes, practicals, projects or long work days.
A combination created for mental work
Caffeine is the star, but it isn’t alone. The formula includes L-theanine, a naturally occurring amino acid in tea leaves, along with a selection of vitamins and minerals designed to complete the product.
A well‑rounded formula: natural prolonged-release caffeine CaffXtend™, L-theanine, pantothenic acid, vitamin B6 and zinc in practical plant-based capsules.
Besides using a branded raw material with a studied release profile, we’ve opted for a clean label formulation, suitable for vegans and made without artificial colors, preservatives or genetically modified organisms.
Is this product for you?
It’s especially designed for university students, examinees and people going through periods of high mental demand. It may also fit professionals with long days, shifts or tasks requiring alertness and focus.
Its capsule format allows easy incorporation at the start of the day or before a study block. Since it contains prolonged-release caffeine, leave ample time before bedtime and always follow the directions on the packaging.
How to complete your routine without adding more caffeine
If you want to extend your routine, you can choose products that don’t add another source of caffeine:
- Brain Care*: a broader formula with plant extracts, citicoline, phosphatidylserine, vitamins and minerals for days when you prefer a caffeine-free routine.
- Evobrain: stimulant-free formula with ALCAR, citicoline, plant extracts, pantothenic acid and zinc, designed to accompany periods of high intellectual demand.
Frequently asked questions about Cafeína inteligente*
Why is it called “inteligente”?
Because it combines prolonged-release caffeine with ingredients related to intellectual performance. Caffeine helps to increase alertness and improve concentration, while pantothenic acid contributes to normal intellectual performance.
What sets CaffXtend™ apart from conventional caffeine?
CaffXtend™ is microencapsulated to release caffeine gradually for up to 12 hours. Its maximum blood concentration is reached later than with immediate-release caffeine, resulting in a more progressive profile.
When is it recommended to take?
It fits especially at the start of the day or before a long study or work session. Because of its prolonged release, it’s best to avoid taking it close to your usual rest time.
Can I combine it with coffee or pre-workout products?
It already provides caffeine, so it’s usually not necessary to add coffee, energy drinks, pre-workout products or other caffeine-containing supplements. If you use several sources, you’ll need to account for the total amount consumed.
Does it taste like coffee?
No. Although caffeine comes from coffee beans, it’s in capsules and doesn’t deliver the characteristic taste of this drink.
Is it only for students?
No. It can also fit adults with long professional days, shifts or tasks that require attention and focus.
