Magnesium bisglycinate + citric acid = ?

[ivannovak]

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,

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.
