Magnesium bisglycinate + citric acid = ?

In summary, magnesium bisglycinate and citric acid can interact in a water solution, forming an equilibrium between glycine and magnesium citrate. However, magnesium does not change form and should not be mixed with other chemicals without caution as it can have unintended consequences.

Hello,
I have a question or two that I need help with:
What happens when you put magnesium bisglycinate and citric acid into water solution?
Does magnesium change form here?

Kind regards,
IN

You can get magnesium citrate (citrate of magnesia, a laxative)
Magnesium bisglynate is used as a supplement for patients with low serum magnesium levels, and sometimes as an antacid to treat acid burps for example.

The reason I mention this is that you should not fool around with mixing supplements and other chemicals because they can interact. This example turns a supplement into a laxative. Not a good idea.

Well technically, magnesium citrate is also a supplement with laxative side effects

Magnesium bisglycinate is presumably a weak base (pKa similar to other carboxylates). So in solution, you would get an equilibrium between glycine (conjugate acid of glycinate) and magnesium citrate.

Magnesium exists as Mg2+ and it wouldn't change. Even in the presence of a strong acid such as H2SO4, you would just get a full conversion of magnesium bisglycinate to glycine and MgSO4.
