5.0 out of 5 starscalm in the storm
By Living it up TOP 1000 REVIEWERVINE VOICE on April 30, 2012
Size: 60 Vine Customer Review of Free Product ( What's this? )
Got these for my husband after reading that theanine can help with stress. He works crazy long hours in a stressful industry and was really feeling ragged and having difficulty staying focused/motivated.
The theanine definitely helps take the edge off the tension, but most importantly is helping him stay focused. This is not a miracle pill that cures all your ills, but it definitely offered him measurable results.
Will post in a couple of months as to the long term results he sees and/or any side effects that may come up.

UPDATE: Have changed from 4star to 5star. My husband has been on this supplement long enough now to really see a change. He is definitely more focused, less distracted, more present. I've also noticed he has cut back (without my nagging!) on coffee consumption and junk food fixes. I'm guessing this is a result of simply feeling so much better and so much less scattered and stressed.

While I don't think this is a "miracle" pill, I do know it has been life-changing for our family and I'm grateful for that!

UPDATE 2 (July 2015): I have been taking this theanine during periods of stress and so has my son. That makes three people in our family who are having good success with no negative side affects using the Jarrow L-Theanine. We all take one per day. If under extreme stress we have all added second dose before bed with no negative effects.

5.0 out of 5 starsL-Theanine Amino Acid for Calm Alertness--Helps My ADD
By Amazon Enthusiast TOP 500 REVIEWER on July 15, 2012
Size: 60 Vine Customer Review of Free Product ( What's this? )
WHAT IT IS: L-Theanine is an amino acid (a constituent of protein) found in green tea. "Suntheanine" is a brand name of L-Theanine produced by a Japanese company, Taiyo International, esteemed for its purity.

WHAT IT DOES: So, what does L-Theanine do, exactly? Well, like all supplements, its effects on your individual biochemistry may vary slightly, so I'll tell you what it does for me.

I drink quite a bit of green tea on a daily basis (averaging a minimum of 4 cups a day), so I'm getting a bit of L-theanine throughout the day, every day. I'm a writer and I find that l-theanine gives me a mental edge: a relaxed concentration that makes it much easier for me to do my job (which involves a lot of research and editing).

HELP FOR ADD: I have very mild Attention Deficit Disorder and I find it noticeably easier to concentrate when I take L-theanine, hence my green tea habit. If I find myself getting impatient or frustrated with a project, it's L-theanine to the rescue--it takes the "edge" off in about 10 minutes. I also feel more relaxed, but with a significant amount of calm, focused energy. It doesn't make me sleepy, but I have experimented with it at bedtime & found that my dreams were more intense. I, however, prefer to take it during the day. Your mileage may vary.

OTHER BENEFITS: The research I initially did on this supplement (before I started taking it years ago) stated that l-theanine works to improve concentration by actually altering brain waves, enhancing the alpha wave phase. It also raises dopamine and serotonin levels (both are feel-good neurotransmitters). Personally, I don't take the supplement daily (remember, I drink TONS of green tea).Read more ›

4.0 out of 5 starsThere are contraindications for Theanine
By Colinda VINE VOICE on March 22, 2012
Size: 60
Before taking this product you should know the drug interactions. I found them on the web.

1. Taking theanine along with medications for high blood pressure might cause your blood pressure to go too low.

2. Taking theanine along with stimulant medications might decrease the effectiveness of those medications.

So if you are on blood pressure meds or need stimulants, you should only try theanine under your doctor's supervision.

Otherwise, I did not find any side effects so I think this is a safe supplement for most people.

5.0 out of 5 starsLet's rock the Alpha Waves
By Thor the Viking on June 13, 2013
Size: 60 Verified Purchase
Our brain emits and resonate specific modes of brain waves such as Alpha, Beta, Delta, and Theta to name a few.

Alpha is the state which is induced during deep meditation - an alert yet relaxed state.

L-Theanine, which is found in abundance in Green Tea, works on Alpha Brain Waves.

This may explain who The Japanese Tea Ceremony involves drinking Matcha Green Tea as a means through which to induce a blissful and deep meditation state, that is both awake yet relaxed.

This supplement strives to reproduce this blissful state that frequent drinkers of Green Tea experience on a regular basis as they sip their Green Tea.

This supplement does not compare to drinking a dandy cup of Ceremonial grade Matcha Green Tea, but it does deliver a calmness that is both blissful and awake.

Please do not take this and expect to fall asleep - this is a specific state which again is a combination of Calm & Alert.

I love L-Theanine, and prefer to get with through drinking Matcha Green Tea (see reviews), but this is a great alternative if you are after an Alpha Brain Wave state.

Always good to stick with natural food sources of "nutraceuticals" such as L-Theanine, rather than the isolated and extracted pharmacological version - which is what this is.

Try Ceremonial Matcha - and compare it to this.

There is no comparison - but again - this comes in a pill for those who want a taste of Green Tea Bliss without the Green.

Worth a try for sure!
