## 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.
