    Caffeine and L-Theanine Capsules

    Caffeine is a common compound associated with coffee and colas, while L-theanine is a natural amino acid found in tea leaves and mushrooms. Combining the two compounds in a nootropic stack or taking caffeine + l-theanine capsules has become more popular, offering a variety of potential benefits to your physical health and mental abilities.

    How Caffeine and L-Theanine Capsules Work

    Caffeine is commonly used to temporarily increase alertness and overall performance and efficiency. While it doesn’t technically qualify as a nootropic, caffeine has still been shown in certain studies to improve your brain’s functions and your own mental performance. Unfortunately, caffeine can come with some severe drawbacks, namely jitteriness, sleep problems, and the inevitable crash when its effects wear off.

    L-theanine is a natural compound. It is an effective nootropic that can stimulate the production of neurotransmitters while interfacing with other neuroreceptors. In smaller doses, L-theanine has been found to improve mental focus, while higher doses of it may create a significant calming effect.

    Stacking L-theanine with caffeine can balance out some of those drawbacks while boosting the effects of both. This combination wasn’t just a manmade discovery either. Caffeine and L-theanine naturally appear together in green tea leaves, which have been brewed and enjoyed for providing relaxation and clear focus all at once.

    Caffeine and L-Theanine Uses and Benefits

    Combining caffeine and L-theanine can amplify and refine the effects of the two compounds to bring out the best of both. L-theanine’s inhibitory presence prevents the hyperactivity and restlessness associated with using caffeine. Studies show that the stack’s results on cognition are significant.

    L-theanine on its own has been shown to promote GABA production. GABA, or gama-aminobutyric acid, is a neurotransmitter that acts as the main inhibitor in the human central nervous system. GABA can block stress messages, reduce neuronal excitability, and generate alpha waves. Alpha waves are associated with a state of extreme calm and relaxation.

    Preliminary studies suggest that caffeine provides certain neuroprotective properties. Research suggests that caffeine may also be an effective alternative for headaches and as a general mood booster.

    L-Theanine and Caffeine Synergy

    Caffeine + L-theanine benefits become amplified when combined as a stack. Studies have shown a variety of beneficial results, including:

    • Improved reaction times
    • Greater dexterity
    • Increased visual acuity
    • Increased mental focus
    • Greater sense of alertness
    • Improved memory recall
    • Greater natural attention span

    Caffeine L Theanine Dosage

    As a dietary supplement, take one Caffeine L-Theanine capsule 1-2 times daily.

    1. Great

      Really great.
      Only bad thing is you can't take it too often if you really want to feel it.

    2. Whoa

      I am writing this on my own accord (not being influenced with freebies or anything) and it's safe to say, this is by far my favorite product from Nootropics Depot. I'm actually coming back to order more and thought I'd drop a review while I was at it.

      I take two in the morning with my coffee and plant-based vitamin. Sometimes I'll take it on an empty stomach but the only downside to that is my already terrible writing gets worse but I REALLY love the other effects (who needs writing anyway?). If I take it with food the effects are, of course, not as strong but still amazing.

      Two caps last me all the way until I got to bed - so over 12 hours - and I'm finally proactive at my job instead of farting around all day. I seriously thought about trying to get a script for it but I definitely don't need it now thanks to this product. I still get side tracked some, but at least I'm super focused on it!

    3. never Gonna give you up, never gonna let me down

      I got more energy, and it’s smoth. Broke my coffee habit, and helped to make me an effective prep cook at my job. on 7th Mar 2019

    4. Great combo

      A bit of caffeine, yet the L-Theanine levels out the jittery feeling some experience after their morning cup 'o Joe.

      And as always, 5 plus Stars for client service, shipping speed, quality, and overall reliability.

      (I'm a repeat client, yet I really need to give kudos to NootropicsDepot -- as I am a bit lazy when it comes to reviews.)

    5. quick energy

      I did love the product I did give me energy but it did give me a side effect that I cannot ignore, and cannot use it, as much as I would love to. on 26th Dec 2018

    6. Don't feel it.

      I get more effect from a bottle of coke, 58mg of caffeine approximately than 2 capsules at once. I don't know what is wrong with it, and it seems I am not the only one with a few people having the same issues.

      ND Admin: The version you bought contains 100mg caffeine and 200mg L-theanine. That L-theanine dose seems to be a bit high for some people, causing them to either feel nothing or a bit tired. We've known this for a while, and have been working on a second option for people that need a bit more push and a little less L-theanine. So we are about to offer a flipped ratio option. This will have 100mg L-theanine and 200mg caffeine. That's going to be a better option for those that feel nothing or get tired from the higher theanine/lower caffeine option we have always sold.

    7. Subtle yet powerfull

      I find the balance to be exactly right. The caffeine is present but the buzz is not. This is the first Nootropic i have tried and it seems a bit strange that i am getting the benefits of caffeine without any jitters whatsoever.

      But, it's also a trap. You might think that this stuff is not working, just because you expect the anxiety to hit you as well. Just be mindful of your body and your mind. Don't go overboard and have too many pills or add a regular coffee from day one.

      That said, after about one week of taking one of these every day, i tried adding some regular (strong) coffee. The result was a very strong case of energy and very strong jitters. The accumulating effect is not to be taken lightly.

      Note that i am very sensitive to caffeine and always was.

    8. Seems better than just caffeine.

      I'm used to drinking a lot of coffee or tea throughout the work day, but thats not always convenient or possible. This is a closer approximation to what I'm used to than just caffeine. on 10th Sep 2018

    9. definite wake up

      So I used to be very big on drinking coffee but because of all the sugar and creamer and whatnot that I'd put into it I needed an alternative. So I had read about combining caffeine and l-theanine and some of the benefits that they bring. Well I can definitely say this stuff works after about 30 to 45 minutes of taking one. I feel my heart rate increase and I feel much more energy and woken up, word of caution if you have any heart issues be careful cuz like I say it will it increase your heart rate but nothing crazy. Again shipping was fast and honestly came before scheduled. As soon as I run out I'm definitely ordering more as it's now part of my daily stack. on 1st Aug 2018

    10. In the zone

      Aniracetam and Caffeine L theanine are my go to nootropic for productivity, especially in a high pressure environment. Aniracetam gives me warm fuzzy feeling in my stomach meanwhile Caffeine+L theanine gives me a smooth laser focus without any jittery. Double thumbs up for ND. on 10th Jul 2018
