Caffeine Active by Quadrat‑S Vitamir is a food supplement in tablet form, containing caffeine — one of the most studied natural stimulants of the central nervous system. The pack contains 25 tablets, providing a controlled, measured dose of caffeine without the need for coffee or energy drinks.
Caffeine temporarily blocks adenosine receptors in the brain. Adenosine accumulates during the day and signals tiredness; reducing its action makes a person feel more alert, focused and mentally awake. Caffeine also mildly increases the release of dopamine and noradrenaline, which many people notice as improved concentration, faster reaction time and a lift in mood. The onset of effect is typically 30–45 minutes, lasting several hours depending on metabolism.
The tablet form offers precise dosing and avoids the acidity of coffee, stomach irritation, tooth enamel impact, and extra calories from additives. It is suitable for:
Typical benefits include:
Athletes also value caffeine for its ability to reduce the perception of effort and delay fatigue during endurance activities.
The Vitamir brand from Quadrat‑S is known in the Baltic and Eastern European markets for affordable single‑ingredient supplements with a simple, transparent composition. This format appeals to consumers who want to know exactly what and how much they are taking, rather than using complex pre‑workout blends with many additional stimulants.
Caffeine is a stimulant and should be used sensibly. It is not recommended in the evening as it may disturb sleep, and should be avoided during pregnancy, breastfeeding, childhood, and by individuals with high blood pressure, heart rhythm disorders, anxiety or peptic ulcers. Count caffeine from other sources such as coffee, tea, cola, chocolate or pre‑workouts to keep total intake within reasonable limits. If you take medication or have a chronic condition, consult a doctor or pharmacist before starting. This is a food supplement and does not replace a varied diet or healthy sleep.
