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, increased anxiety, 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:

Does its job I suppose. I think I would see better results if my tolerance wasn't so high. Shipping was fast Isaac on 3rd Aug 2017
Works amazingly well. Great concentration, without the jitters Ahil on 20th Jul 2017
When I take one of these in place of regular coffee, I feel about as awake as I would have with the coffee. Beyond that, not much to notice. (I like regular coffee and it doesn't make me jittery.)
At some point I could try taking two of these and maybe I'd notice more--but I never have. Unknown on 4th Jun 2017
Gives a good amount of caffeine to get the day going, with L-theanine to balance out the negative effects from caffeine. Jeff on 20th May 2017
I've been taking these tablets for about a month now, and I really don't notice anything after taking them. Unknown on 19th May 2017
This combo has been working great so far. It provides a sense of clarity and ability to focus on tasks better. Unknown on 9th May 2017
Realy nice energy i like it Dancho on 3rd May 2017
These pills are the best! Love this L-Theanine / Caffeine ratio, it's like caffeine but without the side effects from caffeine.
And NootropicsDepot always delivers great products, super fast! Unknown on 12th Apr 2017
I have tried a few different racetams and had quite disappointing results. They're quite inconsistent, one day they may work the next they don't. Or you have to take them for 3-4 weeks before you notice any effects. So I was very happy when I tried these caffeine & l-theanine capsules. They work great...every time! They give me a nice boost in focus and motivation but with the calming effects of the l-theanine. I don't get the anxiety or edgy feeling as I would when drinking coffee. Its a nice relaxed buzz.

I am really happy with the pills i bought. They keep me very focussed at work. Also when I come home i'm much more productive and less lazy. I can read my books in the evening without getting distracted by tv or my smartphone all the time.
I ordered a bunch of boxes of 180 pills to reduce the shippingcosts to Belgium. The only thing is that i can't find an expiration date on the containers. Do they expire or at one point become less effective by time?
**ND Admin- Both caffeine and L-theanine are very stable. As long as they are stored properly away from moisture and sunlight, they should be potent for many years. You can find the production date of your bottle. The last digits on the end of the lot number are the production date. Unknown on 5th Mar 2017
