Hi, is the Magnesium L-Threonate in a glass bottle and what other ingredients?

The bottle is dark amber plastic. 48mg magnesium, 670mg Magtein (Mag L Threonate). Other ingredients: Cellulose (vegtable capsule), brown rice flour, may contain one or both of the following - magnesium stearate, silica.

Does it have any ingredients from China

I am assuming because it has pending patents in the US stated as follows: Magtein (Magnesium L-threonate) is a trademark of Magceutics, Inc. and is distributed exclusively by AIDP, Inc. Magtein is covered by U.S. patents #8,178,118 and #8,142,803 and patents pending." that the ingredients are from the U.S. but I don't know that for a fact.

Why does the recent batch "A 243187" have a distinct toxic hydrocarbon chemical smell? What is the product contaminated with?

I have batch # C 249348 and they smell rancid???

Is this Vegan and Non-GMO?

It is not indicated on label. You would have to ask Swanson Vitamin Co directly.
