## 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.

It definitely helps boosting my mood and making me calm. I would say effects last around 4-5 hours. Effects are very instant for me. I can feel it working within 1-3 minutes. It comes in a powder form and serving spoon is very tiny that measures at 200mg (with top being flat after filling) which is more than enough for me. Great value with 500 servings compared to pills. I would recommend to not take more than 2 servings, as long term research has not been done yet on this form of amino acid.
