L-Theanine by Natural Factors

Posted by Reviewer1860238 on Aug 05, 2008

This is an awesome product...I have turned my friends on to this. It really works and you don't have to worry about side effects. If one doesn't work take another. One of my hyper friends couldn't believe how mellow and relaxed she felt after taking two...everyone has said the same! Thanks for all the reviews! They really help!

Like these

I get these for my 12 year old. She loves them. She likes the taste and says they help her relax to go to sleep. Studies show that they are good for boosting brain power in teenagers!

Very Soothing

Posted by Reviewer1752904 on Dec 12, 2009

This product is fabulous! It's a natural anti-anxiety supplement that doesn't make me tired, jittery, or spaced-out. I only need half of a tablet each morning, and if my day is particularly stressful, I can take the other half. I love the absense of nasty side effects. In my opinion, this works better than other natural (Valerian) or prescription (Xanax) products. Highly recommend this!

Taste great and helps sleeping for my 5 year old!

My son is almost 6 and has always been a restless sleeper with occasional bad dreams. He loves to take these and they have really made a difference 1 month into the bottle. He sometimes sleeps with us too and the difference is sooo noticeable. No more kicking and moving around and no more bad dreams!

Great product

This product gently helps me fall asleep more quickly and sleep more soundly. The tablets taste great...like candy. I have not noticed any side effects.

Worked for me

I had to give it a few days, but it really helped calm my anxiety due to ongoing trauma.

Excellent product!

If you are worried about the effects of other L-Theanine products that contain green tea because of the caffeine, and taking the product on an empty stomach, well, this is the product that you should be taking! I can take this on an empty stomach, it's extremely calming and it doesn't make me feel dizzy.

I initially bought tried this product after purchasing smoothies with an enhancer called "stress relief." I loved the calmness that I received after consuming these smoothies and I inquired as to what the product was that they used and it was L-theanine. I researched the product and found iHerb. I've been using the product for over a year now and its gotten me through some stressful times and reduced my consumption of other herbs that my doctor told me to stop using St. John's Wort, etc. Not to mention, I've given this to my daughter (just one tablet), in the mornings with her vitamin, and its helped her be less nervous and anxious in school. She says she is able to focus better and relax. I think its great and it is now a household staple in my household. I highly recommend it to children with ADHD, Asbergers', or adults with bouts of anxiety, and stress. It is expensive, but it's definitely worth it.

Suntheanine L-Theanine chewables

Great products for helping get control of escalating anxiety. Will help take the edge off so you can get a grip on things and put them in perspective. Works well too if you have had too much coffee. Will help with the "coffee jitters".

I give my kids one of these every night and it really does help them to calm down and sleep better. You really notice the difference especially when you run out and they haven't taken them.
