## Questions & Answers

**Q: Are Nutricost's product tested by an Independent Lab?**
A: Yes they are.  Every batch gets submitted for 3rd party testing before distribution.

**Q: Does this product's "other ingredients" include Magnesium Stearate?**
A: It actually contains gelatin, Rice flour, magnesium stearate, mixrocrystalline cellulose, and silicon dioxide. The picture they have up only shows gelatin and rice flower which is not just misleading/lying but incredibly dangerous.

**Q: what country is this sourced from? China?**
A: Honestly, I do not try to discern the source country for every product i use ... I make purchase decisions on a variety of factors, and country of origin just isn't among the top few. I use for my hyperactive dog and it seems to work nicely.

**Q: The label on the box says 1g per serving and the description here says 200mg per scoop with the little spoon that comes with it. What is correct?**
A: 1g per serving of L-Theanine is definitely not correct. 200mg is the correct serving size. The included spoon (leveled off) will amount to approximately 200mg.

### ⭐⭐⭐⭐⭐ Review
*by D***Y on 4 January 2026*

【知っておくべきこと】 ①睡眠導入効果はない 本製品を摂取しても眠くなることはありません。よく言われる「寝つきが良くなる」という効果は、個人的にはないと考えます。 そもそもなかなか眠れなくて困っている人は、本製品の効果を実感できることはないでしょう。 ②本製品を摂取した上で十分な睡眠時間が必要 深い睡眠で、睡眠時間の短さを補うことはできません。サプリに頼る前に、まずは生活習慣の改善から。 もちろんカフェインの摂取管理や、寝る直前のスマホ使用制限なども重要です。 ③劇的な効果ではなく「地味」な改善 最初の1回は鮮烈な目覚めの良さを実感できるかもしれませんが、その後は至って普通な目覚めかたになります。私の場合はあまりにも深く眠ってしまうせいで、かえって目覚めが悪く感じることすらあります。「これを飲めば目覚めスッキリ！疲れもバッチリ取れる！」という製品ではありません。 【実際の効果】 Apple Watchで睡眠状況の測定をしているのですが、効果は一目瞭然です(画像を参照)。自覚はありませんが、まさに泥のように眠っているようです。 日中の眠気もあまり感じなくなり、生活の質は確実に改善されています。 【総括】 「もともとある程度良好な睡眠習慣を続けている人が、特権的にバフを得ることができるサプリ」と言えるのではないでしょうか。万人におすすめできる製品とは言えませんが、私は良い製品だと確信しています。 睡眠に関して深刻な問題を抱えている方には、残念ながら効果は(おそらく)ありません。他の方も言う通り、医師に相談しましょう。
