Amoxicillin

  • Trade Names :

    • Amoxil
    • Trimox
    • Wymox
  • Amoxicillin is a relative of the antibiotic penicillin, but has been modified to have a broader spectrum of effect.
  • Bromelain
    According to two studies, the supplement bromelain (from pineapple stems) may increase the absorption of amoxicillin. 1,2 This effect might help the antibiotic work better.
  • Vitamin K
    There are concerns that antibiotic treatment might reduce levels of vitamin K in the body. However, this effect seems to be slight, and only significant, if at all, in individuals who are already considerably deficient in vitamin K. 3–6
