Magnesium bisglycinate + citric acid = ?

Click For Summary
SUMMARY

Mixing magnesium bisglycinate with citric acid in a water solution results in the formation of magnesium citrate, which has laxative properties. Magnesium bisglycinate serves as a supplement for individuals with low serum magnesium levels and can act as an antacid. The interaction between these compounds leads to an equilibrium between glycine and magnesium citrate, but the magnesium ion (Mg2+) remains unchanged. Caution is advised when combining supplements, as this mixture can produce unintended laxative effects.

PREREQUISITES
  • Understanding of magnesium bisglycinate and its uses as a supplement.
  • Knowledge of citric acid and its role in chemical reactions.
  • Familiarity with chemical equilibria and acid-base reactions.
  • Basic chemistry concepts regarding ionic compounds and their behavior in solution.
NEXT STEPS
  • Research the properties and uses of magnesium citrate as a supplement.
  • Study the effects of combining different dietary supplements and potential interactions.
  • Learn about the chemistry of acid-base reactions and equilibrium in solutions.
  • Investigate the physiological effects of magnesium on human health.
USEFUL FOR

Individuals interested in nutritional supplements, healthcare professionals, and anyone exploring the interactions of dietary compounds and their effects on health.

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.
