Semper Dråber
Drops with 1 strain, L. reuteri DSM 17938, for full-term babies from birth
In short: Drops with 1 strain, L. reuteri DSM 17938, 100 million CFU in 5 drops. That is the strain and dose used in the trials in babies with colic. The drops contain no vitamin D, so the baby still needs ordinary vitamin D drops.
