I only watched this as I was researching Ashwagahnda, and your video of that brought me here……………….. and now I have subscribed. Wow, you certainly know your stuff………………….. this is fascinating, I,ll be getting some L-Theanine, your info rang bells for me! Thank you so much Zach!….PS I am very “sensitive” to caffeine and other stimulants. I bought Ginseng a while back but had to stop taking it as I was hyper and noticed I was talking to folk like I was on Cocaine or such LOL.
What is the dosage for a 52 yr old man who weights 215 lbs for anxiety?
Im amazed! You give information in a concise way. I am so excited about this.I just recently went to my psychiatrist I’m struggling with depression and anxiety and I am on 5 different drugs to try and help with these issues. I recently started taking this…I live on cokes so it should REALLY work! Thank you so much for all your work and information. ��
Hey everyone! I’m not a guys even in a guise. I am a woman. I realize “guys” is a Germanic slang origin for people, overall, & also realize the antonym for the word is girl. Are there other non-slang words to address people with that you like?
Amazing! I have been taking 250 mg of LTheanine every day with Starbucks Doubleshot energy. It’s working wonders for my ADHD. Also, Panax Ginseng has a similar effect too. So I take ginseng in the evening.
I’m glad you mentioned glutamate because I suspect I have too much. What’s the best way to measure these?
My son claims GABA with little B6 works wonders for sleeping.
Strangely has the same benefits as no fapping.. crude but true
I have Blood pressure issue and im taking maintenance. Is it safe to take l theanine?
Thank you very much for your video. I had read the study that I-Theanine lower down a blood pressure, but if my blood pressure already low, how it’s will works? Thank you.
Another fabulous investigation, as always you have intrigued and elucidated me on a worthy topic. I’m not always excited by ‘side effects’ buy these possibilities are worth exploring.
Hi, I ve just subscribed, your chanel is very interesting. Thank you for all the information you provide, very interesting ropics. Could you please talk about 5-htp. Thanks
Life expectancy by taking L Theanine does make sense. Asian countries are the largest consumers of green tea which, as mentioned, is the only dietary source of it. Hong Kong & Japan are currently the top 2 countries in life expectancy.
I tried it this week and told my parnet about it and he loves It. I have social anxiety and it’s helping so muchhhh. These are the things doctors never tell you
Love this video. I enjoy mot being taught something like I’m an idiot. You do am amazing job getting not to deep and not to dumb downed
I missed the part where you talk about the best time to take L-Theanine, also how fast does it act in your system. If you could comment that would be great. Thanks!
Found this video because I found L-theanine on the ingredients list of the Brain Force Plus I just got in the mail from infowarsstore.com thanks for teaching me about l-theanine
Excellent presentation, clear and concise. I use powdered theanine primarily, BulkSupplements is great. 200 mg really does nothing for me, my sweet spot seems to be 600-800 mg. Great for general relaxation, as a nootropic stack with caffeine (as you explained so well), and as a sleep aid. As this seems to work for me, not sure there’d be any benefit to trying the patented form (Suntheanine). It’s also significantly pricier than the stardard powders and capsules.
So if Theanine is helpful for sleep, yet makes the brain more alert, would it be helpful to take it at night as a potential sleep aid or not?
So refreshing to hear someone citing their sources in an easy to understand way instead of a click bait “3 week review!” style vid. Good stuff man(:
Thanks you so much. I’m getting very bad panic attack when I’m driving. I hope this helps
Is their a tolerance limit known for l theanine? Also I found this study interesting.
https://www.ncbi.nlm.nih.gov/pubmed/23324588
Thanks
what does l theanine do to your sex drive? i have performance anxiety and almost no libido.
Hope for answer!

If I just take L theanine with out caffeine is the still beneficial or is it preferred with caffeine
Is this the honors class? Feels like I should be following along in with a text book.
Will our body develop any tolerance to this amino acid if taking 500 mg of it per day?
What if you dont drink coffee or caffeine in the mornings. Can you still take the L-Theanine?
I have GABA but have never felt any help from it. Too bad I have this big box of gaba.
To how many grams of green tea leaves does this 200 mg translate?
Hello! Great video, very informative! Question could L-Theanine possibly have a crash or hangover-like outcome the next day? I get that with caffeine, even a medium size coffee, I’ll have a noticable lack of energy the next day. Which is why I don’t consume coffee regularly (and hence it is a nice treat when I do!) and stick with tea. Yesterday, I received good matcha tea and today I have had two cups of it (4 tsps). I believe matcha contains L-Theanine in a near 1:1 ratio, with a bit more caffeine (17mg:25mg per tsps). I certainly feel more relaxed and definitely feel the caffeine kick, too. It’s definitely a more relaxed ‘up’, comparable to utilizing CBD. My question and concern is, to be determined tomorrow if I will feel a crash. Perhaps I will just because of the caffeine, so, I suppose I’d need to try with L-theanine alone only to see by myself. I’d love to hear your thoughts!
reading about keto supplements, saw L-Theanine, found this vid.. deffo buying it now! thanks!
How many grams of Matcha do I have to drink to have 200mg of L-Theanine?
Does it matter if it is suntheanine or not? I’m having problems with sleep and take half an hour before bed 150mg suntheanine without cafeïne, but it doesn’t make me sleepy?
I took a drink with this and I swear it was like I was high on drugs. Tired. Thinking deeply but full of daydreams. A weird sense of peace.
It’s such a shame as l-theanine did reduce my anxiety and stress markedly but also caused my PVC’s to become multifocal and even PVC couplets which is dangerous. Since stopping they have gone back to unifocal PVCs.
Fantastic video! I know l-theanine is considered super safe but do you think there is a max limit in a day? I get 100mg daily from Mind Lab Pro, 400mg as a supplement along with 200mg caffeine (mainly this much due to caffeine capsules being 200mg/capsule) and in the evening 500mg as a sleep aid (along with other stuff like Valerian Root in the mix).
HUH? SAY WHAT??? ok..I think I got it, but I have anxiety! Lol. But to be kind, thanks!��
I take GABA and it works, but wy Brain-Blood Barrier is broken and my brain is messed up.
Nobody is sure about any of this, I read that L-glutamine can reduce intestinal spasms, how can this be if it is a stimulant??
