NutricostL-Theanine 200mg, 120 Capsules, Double Strength - Non-GMO, Gluten Free

Q: Are Nutricost's product tested by an Independent Lab?

Yes they are. Every batch gets submitted for 3rd party testing before distribution.

Q: Does this product's "other ingredients" include Magnesium Stearate?

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?

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?

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 works

Good value and I found it helpful for sleep. Perfect to buy in 200mg. You can take a maximum of 10000mg in 24hrs. I rarely take more than 2. It works for me. I also take one occasionally if I have had too much coffee.

Defective and non returnable.

The supplement has no impact what so ever. It does nothing. No effect at all. You will feel the same way you felt before taking them. You can't return the product for being defective either. A total waste of money. Do not bother.This is the second time I have tried to buy a supplement from Amazon and found it to be completely ineffective. The first time I ordered a supplement that had worked for me in the past, so was very surprised it didn't. At least I was able to return that one.Nutricost or Amazon will not allow a return for this. Do not waste your money. It will not help you sleep, it will not improve your focus. It also has ingredients that are not shown in the product image (rice flour).I remain tired, stressed, and now extremely disappointed.
