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:
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.

Caffeine & L-theanine combo is my go-to product for daily use. The combination is a great way to start the day and a great way to re-boost mid-day. It provides a good amount of energy without the jitteriness. There is a reason why so many people recommends this combo. Unknown on 22nd Oct 2017
My chess elo climbed more than 300 in a week after taking this thing (1445 to 1765)

try it Unknown on 30th Aug 2017
Since I mostly use it in conjunction with other substances I can't really be sure about the concentration part.
The only downfall is that due to me being a fast caffeine metabolizer I would prefer if it was 200mg/200mg.
Overall, good morning starter pill. Neurious on 24th Aug 2017
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
