Hey SoulfulYin,
Thanks for the update,
Just a couple of things, reading through your messages

1. Pepper is fine. It helps aid digestion. This doesn't need to be avoided.

2. I take Magnesium Threonate, however I don't recommend it for you. One its very expensive and if your mom is magnesium deficient she will readily absorb any kind of magnesium.

I would go for Magnesium Oxide. This what I started off with. There are many types of magnesium because magnesium can't be by itself as a molecule it needs to be bound to something else to make it stable.

A Mg supplement is best absorbed on an empty stomach, but if she has any side effects (unlikely) take it with a meal.

Hope this helps, keep up the good work.

Magnesium oxide tends to be less readily absorbed into bodily tissues than other forms--it tends to get dumped into the intestines much faster, and therefore can have quite the laxative effect. Of course, some people use it precisely for that reason.

In terms of getting magnesium into the nervous system, it likely better to have it compounded it a more complex molecule, such as a malate or chelate, that is absorbed more slowly. These still may tend to have a laxative effect, but not as much (and these also tend to be a little more expensive than oxide).
