Overview

L Theanine is an amino acid which can be found naturally in green tea. It has been shown to promote relaxation and a restful state without causing drowsiness or reducing alertness. It has been suggested that L Theanine can increase certain neurotransmitters and alpha waves produced by the brain which encourage a calming effect.

For many years people have consumed green tea due to its relaxing properties. L Theanine is the active ingredient within green tea that helps to promote this feeling of relaxation and calmness.

L Theanine has a number of beneficial effects including its ability to promote relaxation and a state of restfulness. Preliminary research suggests L Theanine can also; support cardiovascular function, improve the ability to concentrate, reduce nervous agitation and also potentially lower blood pressure. It is also suggested that L Theanine can promote relaxation and encourage deep sleep.

It is suggested the calming effects are produced by increasing levels of GABA (gamma-amino-butyric acid) an important inhibitory neurotransmitter in the brain. GABA has been shown to reduce the feeling of excitability, restlessness and insomnia. L Theanine may also increase levels of dopamine, another brain chemical which can enhance mood.

Although L Theanine is found in green tea it does not contain caffeine which is often associated with 'edgy' and 'jittery' side effects. L Theanine works to offset caffeine's hyper effect with a calming effect.

This chemical is brilliant especially in conjunction with caffeine. For me creates sharpness ,clarity of thinking and at the same time focus and tranquility. I recommend

Doesn't have any effect what so ever. Have tried double the amount recommended on the packet but is totally ineffective as a relaxant. I'm just holding on to the idea that it might actually be good for me.

Valium

Works a charm

I've been using L Theanine for several years now to help with my anxiety and sleeping problems. I first found out about Theanine because Japanese green teas like Gyokuro contain *a lot* of it - so much so that you can actually taste it. I drink a lot of speciality imported green tea which has always helped me to relax, so I thought I'd venture into Theanine. The taste is amazing, very much like Gyokuro but without the caffeine. Mixability is fine, I usually have 1/4 to 1/2 a MP small scoop (a lot!) which dissolves with a few shakes, or within moments of stirring into a hot drink. As for the effectiveness; I find that the larger the dose, the quicker the effects seem to appear - usually it takes about 30-40 mins for the effects to become noticeable, but it's not as if it hits you, you just realise that you've been really calm and focused for the last 10 minutess, etc. It seems to allow me to concentrate on things better, which helps with studying. It's also great before bed as it helps me get to sleep quicker and my quality of sleep seems to also improve. I once tried a mega dose of a heaped MP small scoop, which after 30 minutes gave me the same kind of headache you get from an Acetylcholine deficiency (for the Notropic users out there who'll understand) - a kind of headache that appears at the front of your forehead, feels kind of 'cold' and lasts for an hour or so. After that, I don't think i was ever so mellow and laid back in my life before. For anyone with anxiety issues, it definitely helps me, so I'd recommend trying it. I cap it and take a cap along with a strong cup of Japanese Kabusecha before meetings with clients or my boss, and the difference to the times I forget to do that is really noticable!

I've been using this L Theanine daily for 2 weeks now, I've taken it with caffeine pro on a few days and had amazing results. This Improved my concentration massively and I felt calm while working, rather than buzzing from caffeine like I used to. I can see why it's great for anxiety and sleep but it kept me feeling calm all day.

Caffeine Pro

I take L Theanine with my green tea extract, at a ratio of 2 green tea extract to 1 theanine. I have no problems at all with jitteryness from GTE, and it also doesn't affect my sleep. It's really good for stress and anxiety, too.

green tea extract

Best on an empty stomach

I use this L Theanine to help me with stress-related sleep problems. I take a teaspoon of it with 2 ZMA. I've tried pretty much everything from herbal remedies to prescription tranquilizers. This is the only thing that actually makes a noticeable difference without the side effects of tranquilisers. Give it a go before you visit your GP.

Goes Well With:

ZMA / Melatonin / 5HTP / Tryptophan / GABA.

my humble opinion

While browsing the net for a way to help me sleep better after giving up smoking, I came across some information that said green tea has a calming effect and may help to give me a more restful nights sleep. So upon further research I found that one of the key ingredients in it was L -Theanine, so being someone who has done weight training on and off over the last 25 years I took a wander through Myprotein's site to see if this amino was available in its neat form and found to my delight that it was. Hence I purchased some and started using it every day, in my opinion as far as the calming effects it is a winner. My sleep has become restful again and my training is now more focused and along with some other supplements I use from Myprotein my progress in the last three weeks has been noticeable. What more can I say other than I think it's great!

L- Glutamine and Creatine

"I have started using another supplement which is very high in caffeine. As I only get to do my workouts around 6pm I don't want to still be buzzing at bed time. The other supplement was giving me really bad jitters. However, the inclusion of a bit of this with the caffeine product, a bit in a drink after my workout and a bit before bed is really doing the trick. I am probably using about 300mg in total split 3 ways. Certainly seems to do the job and you can smuggle it into a drink without noticing it (apart from it floating a bit on the surface)."

"As the title says if you get agitated if you have caffeine then you need this, i used to get the jitters form only 50mg caffine without this now i can take up to 350mg caffine with 300mg of this and no jitters at all.\nVery calming when 300mg is taken 1 hour before bed, sleep is very good."
