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.
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.
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.
Caffeine + L-theanine benefits become amplified when combined as a stack. Studies have shown a variety of beneficial results, including:
As a dietary supplement, take one Caffeine L-Theanine capsule 1-2 times daily.
Nootropics Depot offers 60ct. or 180ct. jars of high quality Caffeine and L Theanine capsules. Nootropics Depot's Caffeine and L Theanine has been lab-tested and verified for both product purity and identity.

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. Unknown on 1st Aug 2018
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. Biohacking wizard on 10th Jul 2018
I'm a proud, habitual caffeine consumer. Only once prior have I opted for caffeine pills, a blue label thing from Vitamin Shoppe. I chunked 'em in a week; too much punch, too jagged, and I'd really rather just drink my caffeine. Nevertheless, these have been really nice. I bought this bottle to round out an order of racetam's with free shipping, just on the off chance that they would be good to have on hand. Tbh, I really like these. Now, it's not a rush like a Red Bull with sugar or a Five Hour Energy, but these are just so much smoother. The Theanine is the kicker because it completely smooths out the caffeine withdrawal. The pep just leaves and you're still clear. I've never taken more than two in a four hour period so take this for what it's worth, but I like to workout or write on these, it's a great little pep. Very clean. Great to have in a pinch or for the commute/before lunch. Most of all, another excellent testament to ND's quality. Chris on 2nd Jul 2018
I take one of these at breakfast, and one of them at lunch, five days a week. No noticeable flavour beyond the half a second it takes me to swallow it (perfectly easy to swallow).
Ingredients are basically the 300mg of active stuff, harmless filler to make it capsule-sized, and a vegetable gelatin capsule wrapped around it all. No problems there.
If you are looking for a pill that makes you want to climb a mountain, these aren't it, but that's not the feeling I'm looking for on a weekday morning in the office, haha.
They don't give you a buzz, pop one and within about two minutes you have the mental state of "alright, let's get some stuff done". And then I do.
Planning on ordering more once this bottle runs out. Recommended. Stephen Smith on 20th May 2018
I was originally turned on to Caffeine+L-Theanine through the product "Soylent". Despite enjoying coffee, I try to avoid it and use it like a utility, only when needed. When switching from standard coffee to "Soylent Cafe" I had a noticeable productivity boost, without the typical detriments (easily distracted, jittery, withdraw symptoms), investigating it led me to L-Theanine.
Soylent is marketed towards those that are too busy to sit down for breakfast and coffee. Sometimes, I'm too busy for even a coffee alone, but I hope to never be too busy to swallow a single capsule. Not only are they convenient, but they're an order of magnitude stronger as well. In addition, they don't agitate my stomach, where with coffee it's a 50/50 chance that i'm going to start the day by spending 20 minutes traveling to and from the restroom.
While I don't take these everyday, I'd never want to be without them. They are a solid backup for when things are rough but you need to keep going. It may be too much for some people but if you can handle/improve your focus, these things can be a huge aid.
I've held off on this review to try and think of some negatives, haven't had any yet. "Works for me" seal of approval. Unknown on 17th May 2018
100mg of clean and quality caffenine hits me like a truck.
wish i could split these in half tbh
sell 50mg! Unknown on 8th Apr 2018
Fast shipping and great product. Gives a boost of energy without the negative effects of caffeine such as jitters or anxiousness. Which is a must for me as I have anxiety issues anyway. I can take one tablet and I am focused and motivated for hours. Thanks nootropic Depot for another great product. Josh s on 8th Apr 2018
Serves a necessary purpose as a mood boost for me; it works and I’m thankful it’s available and that I am able to purchase this without having to go through the bs-procedures of obtaining a monthly prescription from a physician lori ann on 5th Apr 2018
Works quite well. 100mg of caffeine is a bit small in my opinion so I personally recommend you take it with a cup of coffee Unknown on 25th Mar 2018
You must try it Unknown on 11th Mar 2018
