September and the Focus Challenge
Returning after summer always means a change in pace: new projects at work, children’s learning processes, intensive meetings, and deadlines.
It’s no surprise that in September, nutraceuticals that help focus, reduce fatigue, and increase productivity are most in demand.
At Vitafoods Europe 2025, one of the key trends was products for cognitive endurance: adaptogens in new delivery systems, caffeine gummies, L-theanine combinations with natural stimulants, and innovative formats for office workers and students.
Caffeine in New Forms: Controlled Energy
Classic energy drinks are gradually giving way to gummy formats and functional beverages.
-
Caffeine gummies provide a mild effect, a controlled dose (25–50 mg), without overdose.
-
They are convenient to use in the office or during study sessions.
-
The exhibition featured products combining caffeine and adaptogens for a longer-lasting effect.
L-theanine: Balance and Focus
L-theanine is an amino acid from green tea.
-
Synergy with caffeine: reduces tremors and anxiety, leaving a feeling of mental clarity.
-
Used in gummy and capsule formats.
-
Studies show that combining L-theanine with caffeine improves reaction time and task accuracy, which is especially important in stressful work conditions (Giesbrecht et al., 2010).
Rhodiola and Adaptogens: Stress Resilience
Rhodiola rosea is an adaptogen traditionally used to enhance endurance and reduce fatigue.
-
Modern products combine Rhodiola with B vitamins and magnesium.
-
New delivery systems at Vitafoods: chewable pillows, microcapsules, and adaptogen beverages, designed for daily intake.
-
Studies confirm reduced cortisol levels and improved concentration (Panossian et al., 2010).
Table: Nutraceuticals for Focus and Energy
| Ingredient | Mechanism of Action | Main Effect | Evidence |
|---|---|---|---|
| Caffeine (gummies) | Adenosine receptor blockade | Increased attention and energy | [Smith, 2002] |
| L-theanine | Modulation of alpha waves in the brain | Focus without anxiety | [Giesbrecht, 2010] |
| Rhodiola | Adaptogen, cortisol modulation | Fatigue reduction, anti-stress | [Panossian, 2010] |
| Adaptogenic complexes | Synergy of plants + micronutrients | Cognitive endurance | Vitafoods 2025 reports |
Practical Recommendations
-
For office workers: caffeine gummies + L-theanine in the afternoon.
-
For students: adaptogenic complexes in capsule or functional beverage formats.
-
For people 40+: Rhodiola + omega-3 for anti-stress and memory support.
Conclusion
September is a time when our body particularly needs help restoring focus and productivity.
Modern nutraceuticals offer new delivery systems and scientifically validated ingredient combinations that can become daily allies for work and study.
