What is L-Theanine?
For many people who find it difficult to promote relaxation or unwind at the end of a long day, L-Theanine supplementation is an excellent method to help you relax and worry less. It is similar in structure and has many of the same effects as Glutamate, a neurotransmitter in the brain that is involved in learning and memory.* 
Benefits of L-Theanine
L-Theanine provides many benefits to those who choose to add it to their dietary supplementation. At normal doses, L-Theanine has also been shown to promote cognition, alertness, and attention.* 
There is further evidence suggesting that L-Theanine may have cellular health benefits, although this is still being studied. [3, 4] Lastly, many individuals choose to supplement L-Theanine with a form of Caffeine, as this combination has been shown to supplement cognitive speed and accuracy and promote healthy attention while switching tasks.* 
The typical dosage for L-Theanine is one 200mg capsule once daily
“I really enjoy the mental boost of clarity and focus I get with L-Theanine and caffeine capsules, and the Theanine-only capsules really helps take the rough edge off of caffeine. I enjoy coffee, and since I don’t want to double-stack caffeine ingestion, the L-Theanine capsules are convenient to take 1-2 with coffee. It works well for me, though it’s more effective overall when I take it in conjunction with caffeine. No surprises there. This is my third order of L-Theanine caps, and I’ll continue to order it from Powder City.”– Trevor P
“I’ve made this part of my night and morning stacks. In conjunction with: 500 mg Magnesium Citrate 300mg Alpha GPC It has provided me the best sleep I’ve had in forever. Normally I wake up intermittently throughout the night, but with these I pretty much always sleep all the way through and wake up relatively refreshed. In the morning, I take it with a few other things, including bacopa, noopept, and coffee-based caffeine. It contributes pretty well, I think. I don’t experience any of the jitters I normally do from the coffee.”– Joshua B
