    Excellent product

    Posted by YURIiherb on Jul 16, 2012

    This product really works and seems no side effect. Finally I get night rest. 不眠症の為、あらゆるものを試しましたが私にはこれが一番合っていました。大瓶3本目ですが身体が慣れて効き目が弱まる事も今のところありません。寝る30分前に飲むだけなので助かってます。難点は湿気でカプセル同士がくっつきやすいのと、ヴァレリアン独特の臭いがキツイ事。

    I've tried many natural and prescription sleep aids over the years. This one works the best for me. Gets me to sleep quickly and doesn't give me that groggy feeling the next morning. I like that it has fish oil as well. Great price and fast shipping from iHerb, too.

    One of the most effective sleep aids

    Posted by Reviewer2654177 on Jan 11, 2012

    Very few things work for me. I have tried most of the ingredients separately, with varied results, but combined seem to work better. Doesn't work when taken every night though; better once every few nights when you know you are going to need better sleep.

    Finished a bottle already and just got 2 more bottles. This product works for me and it might be varied for others.

    Excellent Sleep Aid!!!

    Posted by Reviewer3202325 on Apr 22, 2016

    I found this product to be the most beneficial natural sleep aid I've ever tried. I recommend this to everyone I know that has sleep problems. It's worth every penny with no side effects. I take it every night as I start getting ready for bed. Thank you Irwin Natural's for an amazing product!! :-)

    I had used your previous sleep aid and was quite pleased with it. This product does not measure up to it. Using the dame dosage did not bring on sleep easily. I had to use more of the product. I would not recommend this product.
