Customer Reviews
Rated 4 out of 5 by from Misleading! I find that the product is very helpful. The one problem I have is the label. It should say 100 mg, which each capsule is. It's easy to misinterpret the label.

Rated 1 out of 5 by from Did Nothing I didn't feel any effects from this brand, and I've found other brands of l-theanine to be very effective. I was very disappointed

Rated 3 out of 5 by from Still Waiting For Results I've been taking this for about 2 weeks now and have not seen a change. I've heard all kinds of good things from Dr Oz on the product, not this one in particular but the actual vitamin. I guess maybe after some time I will see a difference.

Rated 5 out of 5 by from Interesting stuff. If the effect was just a little stronger, this stuff would probably be illegal.

Rated 1 out of 5 by from don't seem to see the results this product offered The label states that this product offers "Supports a Calm, Relaxed Mood". I have not found this to be the case. It does not support a calm relaxed mood.

Rated 3 out of 5 by from Good product, but not really $ saver This product is advertised as 200mg in the search, but it is really 100mg per pill (200mg per serving). You must read carefully. Same price as you can find elsewhere. Otherwise, quick shipment and convenient.

Rated 5 out of 5 by from Give to my cats I can't judge quality since I'm no scientist, etc. I buy this product to give to some of my rescued cats. I do have to divide the capsules for the cats and that's a big inconvenience but the savings over the veterinarian's product makes up for the trouble. I have increased the number of cats on this product and am reordering. Being an animal rescuer means that I have to find a great product for the lowest price and I am very happy with Puritan Pride's L-Theanine.

Rated 4 out of 5 by from Good product but not as potent as Solaray I have been using this product for months now. I have found that Solaray is more potent of a product but for the value this product is great. Almost as good as solaray brand. Over all I am very happy with this product and I will keep using it.

Rated 5 out of 5 by from Wonderful product This is a wonderful product and it really works. I had a chance to use other products from different stores and they really didn't work as good. This particular product does exactly what it is suppose to do. I really appreciate it.

Rated 3 out of 5 by from too many ingredients for a single amino acid Why so many 'other' ingredients in a single amino acid ingredient - please check the label.

Rated 2 out of 5 by from Not what I expected The product will make you sleepy. I bought it to use as a stress reliever. If you take it at bedtime it might help you sleep. I couldn't take it in the daytime. Need to do some more research on it.

Rated 5 out of 5 by from L-Theanine replaces a product I take because I can no longer get what I had taken for 5 years. I had tried L-Theanine to replace the calm tabs I took for 5 years. To my surprise & joy,it worked for me in 20 minutes. I just take an extra capsule whenever I need the extra but otherwise I am thrilled that I do not need to do the trial & error. That stress is gone. I also sleep much better especially if I take one 20 minutes before going to bed.. I take 2-3 a day & sometimes 4. I know that all things like this work differently for every one.Some takes a few days or weeks & some does not work for some.

Rated 5 out of 5 by from Really works I run as a high tempered person, easily set off. After taking this supplement I was able to keep my cool much easier. I didn't take it for a couple of days because I was lazy, those couple of days my husband kept saying "whats wrong baby". Lol i guess it helps much more then I thought!!!

Rated 5 out of 5 by from More People Should Know About This I currently take it at my job because working at a casino gets very stressful. If I take between 100-200mg, it seems to make a difference. For example, today I felt that "if chaos would have broken out in the place, I would have remained completely calm" ...that sort of feeling. I'm also a musician and it relaxes me before band practice. Awesome!

Rated 5 out of 5 by from It works! This product is amazing. It works almost immediately. It calms/de-stresses me. It is unbelievable.
