Can I Take zinc and magnesium Together?

SUMMARY:

Zinc and magnesium are generally safe to take, but they can interfere with each other’s intestinal absorption when taken together, so timing or dosing adjustments are sometimes recommended.

ADDITIONAL NOTES:

Both zinc and magnesium are divalent cations that can compete for absorption in the gut; taking large doses of both at the same time may reduce how well each is absorbed. For most people at typical dietary or supplement doses this is not dangerous, but separating doses by 1–2 hours can improve absorption. High doses of zinc can cause gastrointestinal upset and long-term high zinc can affect copper levels; high magnesium doses can cause diarrhea. Monitor for reduced effectiveness if using therapeutic doses and consult a provider for personalized dosing.
