Caffeine + L-theanine is a two-component dietary supplement that combines a strong dose of caffeine with the non-essential amino acid L-theanine. You will appreciate caffeine, especially thanks to its connection with increased alertness and improved concentration. L-theanine from green tea functionally complements the whole mixture. It is thus an ideal choice for students, managers, and athletes.
Caffeine + L-theanine – a functional combination with caffeine that improves focus and alertness
Caffeine + L-theanine is a functional dietary supplement that offers a proven combination of two substances sought after in the world of fitness and biohacking. The base consists of anhydrous caffeine in an effective dose of 200 mg. It is the world's most popular stimulant, which helps increase alertness and wakefulness while also improving focus and concentration. This makes it an indispensable aid during demanding work, studying for exams, or long drives.
You will also appreciate the effects of caffeine in sports. When consuming 3 mg per kg of body weight approximately an hour before activity, it contributes to increased endurance performance and capacity. It is, therefore, a great partner for runners, cyclists, and even crossfitters, helping them maintain maximum concentration on each repetition and training effort.
The whole mix is harmoniously complemented by L-theanine in the amount of 100 mg. This amino acid is commonly found in green tea leaves (Camellia sinensis). It is thus an ideal choice before demanding mental or physical performance. It comes in the form of practical capsules and, thanks to its purely plant-based composition, is suitable for vegans. Moreover, it contains no gluten, lactose, or GMOs.
Other benefits include the mutual synergy of these substances. L-theanine is often used in this duo to harmonise the overall effect. This combination is especially popular among those who prefer a smoother onset of effect and seek a more stable course without sharp fluctuations that can sometimes accompany the use of standalone stimulants. Give yourself the right boost and get closer to better results.

Caffeine + L-theanine - GymBeam

The product contains 200 mg of caffeine and only 100 mg of L-theanine. This 2:1 ratio is exactly the reverse of the scientifically recommended ideal ratio for focus (which would be 1:2 in favor of L-theanine). Due to the excessive amount of caffeine and the insufficient amount of L-theanine, the effect is identical to that of a standard caffeine tablet: it causes a rapid heartbeat and "nervous" energy, rather than the calm, clear focus for which this combination is taken. It may suffice as a pre-workout stimulant, but for those seeking assistance for mental work or studying, I do not recommend it, as it is more likely to fragment your attention than to improve it.Was this review helpful to you?Peter Klapko

You should simply be mindful of the total daily caffeine intake, as the tablet contains a significant amount of caffeine. Primarily, do not combine it with coffee at the same time; instead, maintain a gap of 6–8 hours.Was this review helpful to you?S. U.
