    The combined effects of L-theanine and caffeine on cognitive performance and mood. Nutritional Neuroscience, 11(4), 193–198. DOI: 10.1179/147683008X301513

    Owen et al. (2008) examined the effects of 50 mg caffeine with and without 100 mg L-theanine on cognitive performance and mood in healthy volunteers. They found that caffeine alone improved subjective alertness and accuracy on an attention-switching task, while the combination with L-theanine improved both the speed and accuracy of performance on cognitively demanding tasks and reduced susceptibility to distracting information. This suggests that L-theanine and caffeine together are beneficial for enhancing cognitive performance.

    Study 2:

    The Cognitive-Enhancing Outcomes of Caffeine and L-theanine: A Systematic Review. Cureus, 14(1). DOI: 10.7759/cureus.20828

    Sohail et al. conducted a systematic review investigating the cognitive-enhancing effects of caffeine and L-theanine, individually and combined, particularly focusing on ADHD. They highlighted L-theanine's mechanisms, such as acting as a glutamate reuptake inhibitor and a competitive low-affinity glutamate receptor antagonist, and caffeine's role in inhibiting adenosine receptors to enhance cognitive function. This review suggests that these compounds, especially when combined, may improve attention and cognitive deficits associated with ADHD.

"I find that I'll take it and get busy and all of a sudden I think: Hey. I feel better.

And that's a nice way for a "pick me up" type of supplement to work. You don't keep feeling like you're dragging, but you also don't feel like someone plugged you into a electrical socket. Just - you feel better and are thinking more clearly, and are getting some more stuff done."

Cool Caff is a specially formulated health supplement designed to enhance focus and energy. Each serving contains a balanced combination of 100mg of caffeine and 200mg of L-theanine.

Cool Caff's effectiveness comes from its two primary ingredients: caffeine, known for its energy-boosting properties, and L-theanine, an amino acid known to promote relaxation without drowsiness, which can counteract the jittery effects of caffeine.

Cool Caff is suitable for adults looking for a balanced energy boost and enhanced focus. It is ideal for individuals leading an active lifestyle, students, professionals, and anyone needing a mental lift. However, it's advised that pregnant or nursing mothers, those with medical conditions, or those taking medications should consult a healthcare professional before use.

Cool Caff is versatile—it's great for improving concentration during work, enhancing endurance and focus at the gym, aiding in socializing by helping you stay alert and relaxed, or simply giving you all-purpose energy throughout the day.

While coffee is a well-loved energy source, Cool Caff offers jitterless energy without the crash often associated with caffeine alone, thanks to the synergistic effects of caffeine and L-theanine. Additionally, it provides a consistent amount of caffeine in each serving, unlike coffee, which can vary.

When used responsibly and as directed, Cool Caff can be a component of a long-term wellness routine. However, it's important to monitor your body's response and consult with a healthcare professional if you have any concerns.

Most users feel the effects of Cool Caff within about 20 to 30 minutes after ingestion, experiencing increased alertness, focus, and energy that can last for several hours.

Cool Caff is designed to minimize common side effects associated with caffeine consumption, such as jitters or a crash. However, those sensitive to caffeine may still experience discomfort. Side effects can include restlessness, nervousness, insomnia, and increased heart rate.

Cool Caff can only be purchased through our official website, or on Amazon!
