Many of you may be concerned about how exercise affects your breast milk but studies show that moderate to even heavy forms of exercise and training does not affect supply or taste.

Does exercise make the milk taste sour?

  • No - this is not true.
  • When we exercise intensely our muscles produce lactic acid. Lactic acid does goes into breast milk, however it is harmless, tasteless and even when you are training really hard - it does not stay present for very long after exercise.
  • Moderate forms of exercise - like pilates- does not produce lactic acid.

Does exercise decrease the supply?
