The absorption of some antibiotics and thus their efficacy is reduced by the co-administration of many minerals, calcium, magnesium, iron and zinc, or calcium-rich foods such as milk.

This applies to two main families of antibiotics:

  • tetracyclines – oxytetracycline, doxycycline and minocycline
  • quinolones - ciprofloxacin, ofloxacin and related antibiotics. 

The effectiveness of such antibiotics can be reduced markedly unless mineral preparations are taken two hours away from them in order to prevent any interaction.
