If you have a healthy organism, a diet rich in fiber and protein and you will never have intestinal or digestive problems. It is very likely that you never feel the contraindications of the water kefir. You will probably enjoy its benefits without any symptoms. However, if you already have problems, mainly at the intestinal level, including constipation or a recurrent bloating sensation, it is possible that with the continuous consumption you will have more problems.


The most common adverse symptoms when taking water kefir are the following:

  • Abdominal pain
  • Abdominal inflammation

These symptoms will decrease as the body adapts to the administration of new live microorganisms. This lasts for 2 to 4 days maximum. When in contact with these symptoms you should take only half of what you had previously taken.

During the first few times, the body and especially the intestine will have to adapt and accommodate to the presence of probiotics from water kefir. While there is a reduction of harmful bacteria inside, during the first days, this readaptation to a new, healthier reality tends to create uncomfortable symptoms that will disappear within a few days. If the adverse symptoms of the water kefir do not disappear with days, it would be better to stop consuming it. Consult a doctor to make sure that everything is fine.

It may seem a bit contradictory that food that helps to improve and strengthen the digestive and intestinal system ends up worsening or increasing the frequency of these symptoms. The reason is simple, our organism is reacting to a change.
