Does this product have any ingredients sourced from China?

Since there is an increasing number of shills paid to answer "no" to "made in" or "ingredients sourced from" questions, how about an agent of Magtein responding here.

How much elemental magnesium and how much L-threonate is included with each capsule?

I suggest you read the most helpful review by RWM dated 10/05/2014. The questions you ask are well defined in that post. I chose Magtein manufactured b Magceutics because the recommended dose is 2 capsules daily. Other brands specify 3 capsules daily, and that is inconvenient and impractical for me. I decided to pay a little more for the original magL-threonate for that reason. This original brand contains 73.5 mg per capsule of Magnesium (from 2042 mg of Magnesium L-Threonate). My choice was one of dosage convenience (2 caps per day). I am still quite pleased with MgT. My physician also approves MgT. I hope all goes well for you!

Does anyone know if the contents of these capsules are tasteless? My mom has issues with pill swallowing so I have to open the pills in her food.

I am using this product for a family member who is recovering from brain trauma after an accident. He can't swallow the pills, so I put the powder into orange juice for him. He says he can't taste it at all. If I add two pills to about 4 ounces of juice, he says it's chalky.

Where can I get a copy of the pre-clinical studies cited?

Here's a couple: I haven't actually read these articles. And, I'm not qualified to comment on them in any case. That said, the compound continues to work for me. https://www.cell.com/neuron/fulltext/S0896-6273(09)01044-7 http://file.scirp.org/pdf/Health_2016052715242163.pdf
