Focus on your best – nothing less

Whether you're training, doing physical work, going through stressful times at work or studying - sometimes you just need that extra spark of focus to get the best out of a situation. And that's exactly why we developed Caffeine + L-Theanine Caps.

Use synergies, unleash your potential

In order to benefit from positive synergy effects, many people swear by the 1:1 ratio of caffeine and L-theanine. What can otherwise only be achieved with many cups of green tea and depends on many other factors, the Caffeine + L-Theanine capsules enable you to achieve quickly, easily and effectively.

Caffeine for the anti-fatigue effect

One serving (one capsule) provides you with 100 mg of caffeine and thus provides an anti-fatigue effect. In terms of structure, caffeine is similar to adenosine.

Keep in mind:Adenosine causes tiredness and relaxation in the human body when it docks onto its receptors. Due to the similar structure, caffeine temporarily binds to the adenosine receptors, leaving little to no room for adenosine. This suppresses your tiredness.

L-Theanine for the perfect synergy

One serving (one capsule) provides you with 100 mg of L-theanine from green tea extract, the same amount as caffeine, ensuring a 1:1 ratio. L-theanine acts as a synergist with caffeine and provides the effects you know from consuming 3 to 4 cups of perfectly prepared green tea - just without all the hassle and side effects like increased urination.

Anytime, anywhere, for everyone

Depending on your needs, you can take up to two servings (two capsules) daily - anytime, anywhere. Since we used a vegan capsule shell, the Caffeine + L-Theanine Caps are also suitable for vegans.
